UK: Absurd new Covid rules that prove the Left just love to boss everyone else around

Like many, I am delighted that the Government has decided not to impose further Covid restrictions — at least until next year.

This welcome late Christmas present not only means that people in England can enjoy New Year's Eve, it also means that many restaurants, pubs, theatres and shops will now be saved from closure.

But not everyone shares my relief. Instead, arguing furiously for ever-tougher restrictions — even in the face of the demonstrably milder threat from the Omicron variant — are Scotland's first minister Nicola Sturgeon and her Welsh counterpart Mark Drakeford.

They continue to display breathtaking political opportunism and a shocking refusal to prioritise people's livelihoods. Meanwhile, their allies indulge in endless handwringing, fury, virtue-signalling and political point-scoring. I've had enough of it all.

As a former Labour MP who was a member of the party for 34 years, it pains me to say this, but parts of the Left love bossing everyone else around.

Gloomy

Restricting personal freedom is the itch the Left loves to scratch whenever it can. Lockdowns and the baffling array of contradictory rules and guidelines have provided the perfect pretext for this.

Yes, the state has a role to play in life. But there is a vast and widening gulf between sensible citizens with jobs, businesses and responsibilities, who willingly accept restrictions while longing for the day when they are lifted — and those who constantly demand further curbs, howling with self-righteous fury and predicting disaster when they are loosened.

In England, these Leftist doom-mongers, including Corbynista Labour MPs, party activists and a ragbag of socialists, vent their spleen online and in some cases in the broadcast media. But in Scotland and Wales, Sturgeon and Drakeford's Left-wing governments (respectively SNP and Labour) actually wield the power to act on their urges.

So despite the encouraging data on Omicron, they have once again been trying to make political capital by upending people's lives more disruptively than Westminster, bringing in draconian new restrictions and decimating livelihoods.

In Scotland, large public events have been cancelled, one-metre social distancing has been imposed in pubs, restaurants, gyms, theatres and museums, and table service is now mandated anywhere alcohol is served. Nightclubs are closed and the New Year's party is effectively cancelled.

I live in Glasgow South, in the constituency I represented for Labour. The streets around me are gloomy and empty as they have been for so much of the past two years. Restaurant and business-owners are facing a second bleak midwinter.

This is not because Scotland's Covid cases are higher than in England — in fact, they are lower — but because of Sturgeon's relentless virtue-signalling which plays a huge role in all her decisions.

With impeccable political cynicism, she always insists on imposing tougher Covid restrictions than the Prime Minister is prepared to inflict.

During much of the pandemic, her press conferences were scheduled slightly before Boris Johnson's, making it seem as if she was acting against Covid with greater urgency. Now, in contrast, she is on the back foot as the Prime Minister appears to have been vindicated by his own policy decisions.

Wales's Labour government, under Drakeford, is similarly cynical. The latest rules in Wales are truly absurd. In a policy decision reminiscent of a Monty Python sketch, Welsh people are currently permitted to go to the pub — but can be fined £60 for going to work.

Like most of the hard Left, Drakeford — a self-professed acolyte of Jeremy Corbyn — is an instinctive authoritarian who clearly enjoys wielding the power to restrict ordinary people's freedoms.

So why does the Left have this sinister authoritarian urge? Part of the answer rests in how they see the role of the state.

Most on the Left believe the state should play an extensive role in people's lives. Many are also convinced it should own and run key industries and services — and take a lot of your income in taxes to do so.

Traditional liberals, in contrast, believe that the state should step back wherever possible and allow people to live their lives as much as possible without intrusion.

Rage

Covid has crystallised this distinction. The role of the individual has been shrunk, the role of the state expanded.

But history offers ample proof of why this is a dangerous move — and the trend takes no account of individual agency.

As John Bell, regius professor of medicine at Oxford University, noted this week, the English have in fact been 'pretty responsible' in their response to the spread of the Omicron variant, regardless of the lack of restrictions.

Yet on social media in particular, prominent Left-wing voices are furious at the Government's 'recklessness'.

And what precisely sparks this rage? It is the belief that they are better people, that they care more, and if you don't subscribe to their view then you are just some 'evil Tory'.

Famously, Harold Wilson once said: 'The Labour Party is a moral crusade or it is nothing.' But that was a dangerously simplistic judgment.

Labour, like any serious political party, should leave the crusading to the Middle Ages and instead dedicate itself to taking practical steps to improve people's lives.

But many on the Left believe in this dangerously messianic vision, and that they are thus better people than those on the centre-right.

The pandemic has given them the perfect outlet to demonstrate this goodness. Their alleged 'fears' about the impact of loosening restrictions or their noisily expressed anger about people not wearing masks both work to bolster their self-importance.

Heroic

Anyone who fails to demand tougher rules is, in contrast, heartless and uncaring. And because the arguments against further lockdowns and restrictions often rest on the grievous effects on the economy, Labour claims that the Tories only care about profits and money.

But who suffers when businesses collapse and jobs are lost? Ordinary workers. The Labour Party too often forgets this because its power base is in the public sector — funded, of course, by the taxpayer's ever-expanding largesse.

Aside from the heroic NHS staff, many public sector employees have worked at home on full pay for much of Covid. It's hardly surprising that so many of them are in favour of further lockdowns.

The Labour Party seems to have forgotten that the public accounts are not some bottomless resource. Instead, when the economy declines, so do the tax revenues that keep public services going.

The Left must learn to abandon the ludicrous idea that people can't be trusted to make their own judgments about how to live their lives.

Two years into this pandemic, Sturgeon and Drakeford should be giving their citizens the facts and figures, and then trusting them to behave sensibly. It is now time British people were allowed to think for themselves.

FDA approves first pill to treat COVID after Pfizer's oral medication reduced hospitalizations by 88%

U.S. health regulators on Wednesday authorized the first pill against COVID-19, a Pfizer drug that Americans will be able to take at home to head off the worst effects of the virus.

The Food and Drug Administration issued emergency authorization for Pfizer's Paxlovid, a pill that is available by prescription only and should be initiated as soon as possible after diagnosis of COVID-19 and within five days of symptom onset.

The long-awaited milestone comes as U.S. cases, hospitalizations and deaths are all rising and health officials warn of a tsunami of new infections from the Omicron variant that could overwhelm hospitals.

'Today's authorization introduces the first treatment for COVID-19 that is in the form of a pill that is taken orally — a major step forward in the fight against this global pandemic,' said Dr. Patrizia Cavazzoni director of the FDA's Center for Drug Evaluation and Research in a statement.

'This authorization provides a new tool to combat COVID-19 at a crucial time in the pandemic as new variants emerge and promises to make antiviral treatment more accessible to patients who are at high risk for progression to severe COVID-19.'

The drug, Paxlovid, is a faster, cheaper way to treat early COVID-19 infections, though initial supplies will be extremely limited. All of the previously authorized drugs against the disease require an IV or an injection.

An antiviral pill from Merck also is expected to soon win authorization. But Pfizer's drug is all but certain to be the preferred option because of its mild side effects and superior effectiveness, including a nearly 90 percent reduction in hospitalizations and deaths among patients most likely to get severe disease.

'The efficacy is high, the side effects are low and it's oral. It checks all the boxes,' said Dr. Gregory Poland of the Mayo Clinic. 'You´re looking at a 90 percent decreased risk of hospitalization and death in a high-risk group - that´s stunning.'

The Food and Drug Administration authorized Pfizer's drug for adults and children ages 12 and older with a positive COVID-19 test and early symptoms who face the highest risks of hospitalization.

That includes older people and those with conditions like obesity and heart disease. Children eligible for the drug must weigh at least 88 pounds.

The pills from both Pfizer and Merck are expected to be effective against omicron because they don´t target the spike protein where most of the variant´s worrisome mutations reside.

Pfizer currently has 180,000 treatment courses available worldwide, with roughly 60,000 to 70,000 allocated to the U.S. Federal health officials are expected to ration early shipments to the hardest hit parts of the country. Pfizer said the small supply is due to the manufacturing time - currently about nine months. The company says it can halve production time next year.

The U.S. government has agreed to purchase enough Paxlovid to treat 10 million people. Pfizer says it's on track to produce 80 million courses globally next year, under contracts with the U.K., Australia and other nations.

Health experts agree that vaccination remains the best way to protect against COVID-19. But with roughly 40 million American adults still unvaccinated, effective drugs will be critical to blunting the current and future waves of infection.

The U.S. is now reporting more than 140,000 new infections daily and federal officials warn that the omicron variant could send case counts soaring. Omicron has already whipped across the country to become the dominant strain, federal officials confirmed earlier this week.

Against that backdrop, experts warn that Paxlovid's initial impact could be limited.

For more than a year, biotech-engineered antibody drugs have been the go-to treatments for COVID-19. But they are expensive, hard to produce and require an injection or infusion, typically given at a hospital or clinic. Also, laboratory testing suggests the two leading antibody drugs used in the U.S. aren't effective against Omicron.

Pfizer´s pill comes with its own challenges.

Patients will need a positive COVID-19 test to get a prescription. And Paxlovid has only proven effective if given within five days of symptoms appearing. With testing supplies stretched, experts worry it may be unrealistic for patients to self-diagnose, get tested, see a physician and pick up a prescription within that narrow window.

'If you go outside that window of time I fully expect the effectiveness of this drug is going to fall,' said Andrew Pekosz, a Johns Hopkins University virologist.

The FDA based its decision on company results from a 2,250-patient trial that showed the pill cut hospitalizations and deaths by 89 percent when given to people with mild-to-moderate COVID-19 within three days of symptoms.

Less than 1 percent of patients taking the drug were hospitalized and none died at the end of the 30-day study period, compared with 6.5 percent of patients hospitalized in the group getting a dummy pill, which included nine deaths.

Pfizer´s drug is part of a decades-old family of antiviral drugs known as protease inhibitors, which revolutionized the treatment of HIV and hepatitis C. The drugs block a key enzyme which viruses need to multiply in the human body.

The U.S. will pay about $500 for each course of Pfizer's treatment, which consists of three pills taken twice a day for five days. Two of the pills are Paxlovid and the third is a different antiviral that helps boost levels of the main drug in the body.

Decisive use of AstraZeneca vaccine may have spared UK from Omicron crisis hitting Europe

Immunity for AstraZenica "can last for life in some cases.”

Britain’s relatively low recent death toll from Covid compared to Europe may be a result of earlier use of the Oxford/AstraZeneca jab to vaccinate the most vulnerable, according to the nation’s former vaccine tsar.

Dr Clive Dix, former chairman of the Vaccine Task Force, told The Telegraph that he believed the AstraZeneca jabs offered more robust, long-term protection against severe disease and death than RNA-based alternatives made by Pfizer and Moderna.

Britain’s Covid death rate has been relatively flat for several months, and there has not been a noticeable surge in Covid deaths due to omicron.

However, many European countries have recently seen steadily increasing death rates and have more Covid deaths on a like-for-like basis than the UK.

Figures from Our World in Data, a website run by the University of Oxford, shows the UK has 1.7 daily deaths from Covid per million people. In comparison, the EU as a whole has almost four.

“If you look across Europe, with the rise in cases, there's also a corresponding lagged rise in deaths, but not in the UK, and we have to understand that,” said Dr Dix.

“I personally believe that's because most of our vulnerable people were given the AstraZeneca vaccine,” Dr Dix said.

The key, he says, is that although the RNA jabs produce a more obvious and rapid jump in antibody levels in lab tests, other vaccines may be better at priming another part of the immune system: cellular immunity.

Cellular immunity includes various forms of T cells, including those that destroy infected cells, and also memory cells, ensuring a person can fight off an infection several years after they are first exposed to it. They are slower to react than antibodies and do not prevent infection, but do halt the pathogen in its tracks, making it harder for the virus to cause damage.

“We’ve seen early data that the Oxford jab produces a very durable cellular response and if you’ve got a durable cellular immunity response then they can last for a long time. It can last for life in some cases.” he said.

The only notable difference, he said, between the UK and Europe’s vaccine rollout was the approach to the AstraZeneca jab.

While Britain used its ample stock to rapidly inoculate the oldest and most vulnerable people, officials on the continent besmirched the vaccine’s reputation and dragged their heels on its approval, opting instead to wait for the Pfizer vaccine.

MRNA vaccines like those made by Pfizer are based solely on the spike protein of SARS-CoV-2, the virus that causes Covid-19, and produce highly specific antibodies. But AstraZeneca, and other jabs like those made by Novavax and Valneva, used a more well-rounded approach, said Dr Dix.

“We know that with adenoviral vector vaccines and adjuvanted proteins you get a much broader cellular response and I think we need to look at all that data across all the vaccines,” said Dr Dix.

He added that there was “nothing wrong” with using Pfizer or Moderna as a booster, but alternative vaccines may be a better alternative in the long-term.

Lab results 'don't always translate to the real world'
The decision to move away from giving a primary dose with AstraZeneca and to only use Pfizer or Moderna for boosters was based on various data, including a major study that showed Pfizer and Moderna to be the most effective. But how these lab results translate into real-world effectiveness remains to be seen.

“I think we're getting a little bit ahead of ourselves by just measuring antibodies and neutralising antibody responses in the lab as that doesn't follow through for serious disease and death,” said Dr Dix.

“If you look at all the data, there isn't a great correlation between neutralising antibody lab results and protection from severe illness and death, they don't seem to correlate.

“And that's almost certainly because the cellular immune response is the important thing to stopping serious illness and death.”

The lab-based studies had also thus far failed to suitably measure T cell levels over time, something Dr Dix says needs to be urgently addressed if we are to establish the best jabs for annual boosters, which he thinks will be needed for the over-50s and the vulnerable, much like they are for flu.

“[The T cell analysis method used in most studies] just tells you that there are some T cells in the blood that do recognise antigens in the virus.

“It doesn't tell you very much about the quantity or the quality of the responses and it doesn't differentiate between the different T cell classes very easily.

“I do think we've lost the battle with transmission. There's no vaccine that is going to change that. I think we should focus on the cellular immune response, and it may just get us out of the woods.”

UK: Covid hospital admissions are down more than 50% on this time last year despite record-breaking surge in case numbers - giving new hope Omicron is a less severe disease

The number of people in hospital with Covid in England is less than half the same time last year – despite cases being three times higher, official figures show.

In a further sign that the Omicron variant appears to result in less severe disease, there were 8,474 patients in hospital with Covid yesterday compared with 19,277 on the same day last year.

It represents a day-on-day increase of nearly 1,000 and is the highest since March 5. But health bosses say there have been no reports of large numbers of patients requiring ventilators like during last winter’s peak.

The most up-to-date figures reveal there were 842 Covid patients in intensive care on ventilators – the lowest level in two months.

Covid case numbers – which were updated for the first time since Christmas Eve – reveal 98,515 people in England tested positive yesterday.

This is nearly four times higher than the 25,619 people who tested positive on the same day last year and is a considerable decrease on the 113,628 cases reported in England on Christmas Day.

It is also lower than the 103,558 cases reported on Boxing Day. The promising figures highlight the vaccine’s protective effects against severe illness, as well as the mounting evidence that Omicron is a milder strain.

A further 143 people in England died after testing positive for Covid yesterday – down 42 per cent on the 246 people who were reported to have died the same day last year.

And yesterday’s figure could be skewed by a recording lag, which saw no fatalities registered on Christmas Day and just three on Boxing Day.

Meanwhile data for London – which No10 has been watching closely – reveals there were 364 Covid hospital admissions across the capital on Christmas Day.

While this was a rise on the 278 hospitalisations reported on Christmas Eve, it is still lower than the 400 admissions per day thought to be the Government’s trigger point for imposing new restrictions.

Last night, the UK Health Security Agency (UKHSA) said there had been 45,307 additional confirmed cases of the Omicron variant reported across the UK.

This brings the total confirmed cases of the variant in the UK to 159,932, but does not include any new information for Scotland and Northern Ireland which have not reported data since December 23.

The number of deaths in England of people with the Omicron variant has risen to 39, while hospital admissions for people with confirmed or suspected Omicron rose to 407.

Why you might hear Omicron before you feel it as first symptom revealed

Omicron symptoms are coming on faster than Delta, it appears.

There are a few telltale signs that you might have the mutant strain – but you may be able hear the first symptom before you feel ill.

If people are commenting on the fact that your voice sounds croaky, and you haven’t been shouting and singing, it might be time to take a lateral flow, The Sun reports.

You might even notice that you sound a little huskier and deeper than usual.

This could be because you are experiencing a scratchy throat – one of the first symptoms of Omicron, according to experts.

Doctors have said patients don’t seem to be suffering with sore throats, as Delta sometimes presents with, but scratchy throats.

During a briefing last week, Chief executive of Discovery Health, South Africa’s largest private health insurer, Ryan Roach, said it was the most common symptom Omicron patients experience.

This is usually followed by nasal congestion, he said, with other common symptoms including a dry cough and pain in the lower back.

A string of hugely positive studies show Omicron IS milder than other strains, with the first official UK report revealing the risk of hospitalisation is 50 to 70 per cent lower than with Delta.

A booster shot is the best protection against Omicron, with early data suggesting it pushes efficacy back up to 75 per cent.

Dr Jenny Harries, UKHSA Chief Executive said: “Once again, we urge everyone who is able to get a booster jab to come forward and do so. It is the best defence we have against this highly transmissible new variant.”

Both lower back pain and a scratchy throat haven’t been reported as symptoms with other variants.

Going by reports from cases in the UK, South Africa and US, these are the most common early warning signs of Omicron:

•Runny nose/congestion

•Headache

•Fatigue

•Sneezing

•Night sweats

•Body aches

While the UK’s National Health Service (NHS) states a new persistent cough, a high temperature and a loss of taste and smell are signs of Covid, many patients have also experienced a sore throat.

The ZOE Covid Symptom Study app has shown that a sore throat is among the most frequently reported symptoms, in both vaccinated and unvaccinated people.

Tim Spector, the leading researcher on the study, presented a YouTube video in which he asked viewers to report exactly how their sore throat feels.

He said: “We are getting a messages that the sore throat people are getting with Covid is a bit unusual, it’s not like they’ve seen it before.

“Maybe in a different place, or it feels differently.

“We might be doing some more research on that to see if we can distinguish these Covid type symptoms from the ones of a normal cold virus.”

Some experts say if you feel unwell, regardless of the symptoms, it is worth getting tested.

If you have a positive (rapid) test, the NHS says “get a PCR test to confirm your result as soon as possible”.

But some experts are saying that at the moment, even if your (rapid test) is negative, it’s worth isolating if you have symptoms.

Prediction Omicron will soon be ‘pretty much gone’ in nation where it was discovered

Experts predict Omicron will have fizzled out in South Africa, where it was initially discovered, within weeks in a huge boost to morale for the rest of the world.

Infections have spiralled in the past week and admissions failed to reach expected levels, as hospitals “never reached capacity”, The Sun reports.

A string of hugely positive studies show Omicron is milder than other strains, with the first official UK report revealing the risk of hospitalisation is 50 to 70 per cent lower than with Delta.

Covid booster jabs protect against Omicron and offer the best chance to get through the pandemic, health officials have repeatedly said.

South African scientists are confident the Omicron outbreak there is receding and may last a total of just a couple of months.

There was a sudden steep rise in cases from close to zero in mid-November to an average of 10,000 daily cases early in December, after the variant was first detected there.

That then fell sharply to around 5000 per day on average.

Francois Venter, a medical professor at the University of the Witwatersrand in Johannesburg, predicted that at the current rate of decline, Omicron would “be pretty much gone” from all of South Africa by the end of January, The Times reports.

Professor Salim Abdool Karim, who leads the country’s pandemic response, said he expected “almost every other (country) to follow the same trajectory”.

He told The Washington Post: “If previous variants caused waves shaped like Kilimanjaro, Omicron’s is more like we were scaling the north face of Everest.”

But John Nkengasong, director of the Africa Centres for Disease Control, said to “be careful not to extrapolate what we are seeing in South Africa across the continent, or across the world”.

Dr Waasila Jassat, of the National Institute for Communicable Diseases (NICD), said: “We saw a very rapid rise in cases and an early peak — and the indications are that since then we’ve had a remarkable drop.”

NICD’s latest report shows that cases up to December 18 have dropped nationally by 20.8 per cent in one week.

In the Gauteng Province, which was the epicentre of the variant, cases have significantly come down by almost half (46 per cent), with drops of between six and 40 per cent in other provinces.

NICD’s Michelle Groome told a news briefing: “Really we feel that this has persisted for over a week and that we are past the peak in Gauteng.” But she cautioned there could be lower cases because people are less likely to come forward for testing during the holiday period.

The nation has been at “alert level one” of a five-tier lockdown strategy since October, with mask mandates, a curfew from midnight to 4am, and ban on indoor gatherings of more than 750 people.

The data suggest Omicron peaked within one month of first being detected, with the impact on healthcare being less severe than previous waves.

While hospital admission have risen, they have so far remained far below the levels seen during previous waves of the pandemic.

Deaths were also and people with Omicron stay in hospital for shorter periods – suggesting, again, milder disease – Dr Jassat said

Copenhagen: Early benchmarks from Denmark on infections and hospitalisations are providing grounds for guarded optimism that highly vaccinated countries might be able to weather the omicron wave

The developments, coupled with Denmark’s speedy rollout of booster shots, have raised hopes the country can avoid the dire surge for which it has been bracing.

“It’s too early to relax, but it’s encouraging that we are not following the worst-case scenario,” said Tyra Grove Krause, the chief epidemiologist at Denmark’s State Serum Institute.

Denmark’s detailed nationwide program for coronavirus testing and analysis gives its scientists a trove of real-time data about the pandemic. Because of that – and because it was one of the first countries outside of Africa to witness Omicron’s explosive potential – it has turned into a European bellwether for what to expect with the omicron variant.

And over the last week, the country has fared better than it was expecting. After surging to record-breaking levels, the number of daily cases has stabilised. Officials recorded 12,500 cases on Thursday, compared to 11,000 late last week.

More important, hospitalisations have come in – so far – on the very low end of what was projected. A week ago, Denmark’s government science institute was said daily new coronavirus hospital admissions could range between 120 and 250 patients by Christmas Eve. In recent days, daily admissions have hung around 125. “That is quite promising,” Grove Krause said.

The early signals from Denmark do not provide any direct measure on the severity of the variant, one of the key questions in this phase of the pandemic. But they track with other emerging data and studies from Britain and South Africa that suggest omicron is less likely to lead to hospitalisation than the Delta variant.

Scientists caution that there are still many uncertainties, and that even if Omicron is less likely to cause hospitalisation, its increased transmissibility means countless sicknesses and disruptions. The virus could also spread so widely that it nonetheless leads to an influx at hospitals.

Concerns remain about the health system in Denmark, Grove Krause said, because Omicron infections are still disproportionately concentrated among the young. For now, Grove Krause said, temporary school closures and social precautions have helped slow the spread – but the country could still see a spike after holiday gatherings that bring together the young and old.

Even as cases have slowed, there are other signs of Omicron’s potential to cause chaos. Over the last two weeks, the number of cases among healthcare workers has more than doubled. A weekly government monitoring report said there had also been two Omicron outbreaks in nursing homes.

Since Omicron emerged in November, scientists have been racing to understand the implications and make sense of a variant that is moving far more quickly than its predecessors.

A few data points emerged this week, with one Scottish study suggesting the risk of hospitalisation was almost 60 per cent less with Omicron than delta. Another analysis, conducted by Imperial College London, said people with Omicron cases were 20 per cent less likely to go the hospital, and 40 per cent less likely to be hospitalised overnight. And South Africa, epicentre of the first apparent outbreak, has seen much lower hospitalisation rates than in other waves.

Even if that level of protection dips over time, boosters “can help us through the next months,” Grove Krause said

Two Common Over-the-Counter Compounds Reduce COVID-19 Virus Replication by 99% in Early Testing

A pair of over-the-counter compounds has been found in preliminary tests to inhibit the virus that causes COVID-19, University of Florida Health researchers have found.

The combination includes diphenhydramine, an antihistamine used for allergy symptoms. When paired with lactoferrin, a protein found in cow and human milk, the compounds were found to hinder the SARS-CoV-2 virus during tests in monkey cells and human lung cells.

The findings by David A. Ostrov, Ph.D., an immunologist and associate professor in the UF College of Medicine’s department of pathology, immunology and laboratory medicine and his colleagues, are published in the journal Pathogens.

“We found out why certain drugs are active against the virus that causes COVID-19. Then, we found an antiviral combination that can be effective, economical, and has a long history of safety,” Ostrov said.

Due to his earlier research with colleagues at UF, Ostrov already knew diphenhydramine was potentially effective against the SARS-CoV-2 virus. The latest discovery has its roots in a routine meeting of scientists with the Global Virus Network’s COVID-19 task force. One researcher presented unpublished data on federally approved compounds that inhibit SARS-CoV-2 activity, including lactoferrin.

Like diphenhydramine, lactoferrin is available without a prescription. Ostrov thought about pairing it with diphenhydramine and ran with the idea. In lab tests on human and monkey cells, the combination was particularly potent: Individually, the two compounds each inhibited SARS-CoV-2 virus replication by about 30%. Together, they reduced virus replication by 99%.

The findings, Ostrov said, are a first step in developing a formulation that could be used to accelerate COVID-19 recovery. It also raises the prospect of further study through an academic-corporate partnership for human clinical trials focused on COVID-19 prevention. Additional research into the compounds’ effectiveness for COVID-19 prevention is already underway in mouse models.

To establish their findings, the research team focused on proteins expressed in human cells known as sigma receptors. In COVID-19 cases, the virus “hijacks” stress-response machinery, including sigma receptors, in order to replicate in the body. Interfering with that signaling appears to be the key to inhibiting the virus’s potency. “We now know the detailed mechanism of how certain drugs inhibit SARS-CoV-2 infection,” Ostrov said.

Data from the experiments show that a highly specific sigma receptor binding drug candidate (with pain relieving properties), and formulated combinations of over-the-counter products (such as diphenhydramine and lactoferrin) have the potential to inhibit virus infection and decrease recovery time from COVID-19, the researchers concluded.

While the findings are encouraging, Ostrov cautions against self-medicating with either diphenhydramine or lactoferrin as a COVID-19 prevention or treatment. The type of lactoferrin used in the research differs slightly from the type that is commonly available to consumers, he noted. Lactoferrin is commonly used as a supplement to treat stomach and intestinal ulcers, among other uses.

South Africa STOPS contact tracing and quarantine

South Africa has announced it will stop contact tracing and end quarantine for asymptomatic cases because containment of the virus is 'no longer viable'.

Promising graphs today highlight how the country's Omicron outbreak has faded after just a month - cases appear to have peaked nationally at 26,976 on December 15, and have now fallen for the last five days in a row.

Health authorities in South Africa, where the Omicron strain first took off, said today that contact tracing would be halted with immediate effect, except for large gatherings or self-contained settings.

Isolation for asymptomatic cases was scrapped while mild and severe cases were told to isolate for eight and ten days respectively.

Close contacts of confirmed Covid-19 cases will no longer have to quarantine whether they are vaccinated or not and are not required to take a test unless they develop symptoms.

South Africa became ground zero for the new variant in late November and saw a meteoric rise in infections, from 670 to more than 20,000 in the space of just three weeks.

But cases appear to have peaked nationally at 26,976 on December 15, and have now fallen for the last five days in a row. On Wednesday they dipped 22 per cent in a week after 21,099 were recorded.

The huge surge in infections raised fears that a deadly wave of hospitalisations would follow, but almost immediately doctors on the frontlines said patients were coming in with milder illness.

But in another promising sign hospitalisations now appear to be levelling off nationally in South Africa, hovering just below 400 admissions a day — compared to a height of 2,000 when Delta took hold.

Admissions dropped yesterday by four per cent, after another 593 were recorded. Deaths are just a fraction of the levels when Delta took hold, with just 99 yesterday.

There are 50 deaths a day on average now, up only slightly on the 20 deaths a day when Omicron was first detected in the country. For comparison, at the peak of the Delta wave there were 600 deaths a day.

South African scientist Dr Michelle Groome said in a press briefing yesterday that infections are now levelling off in three of the country's nine provinces after peaking in Gauteng about a week ago.

Hospitalisations and deaths are expected to rise for another few weeks even as cases fall because of the lag between infection and severe illness.

Figures on South Africa's Covid cases, hospitalisation and deaths are compiled by the country's National Institute for Infectious Diseases.

Its figures show that the seven-day average for Covid cases across the country is now falling, dipping from a high of 20,791 a week ago to 17,440 yesterday.

The country is currently carrying out 58,000 swabs a day, comparable to the numbers done in early December when cases skyrocketed but down 14,000 on a week ago.

South African Covid cases fall AGAIN by 22 per cent on last week fuelling hopes that their Omicron wave is over
Daily Covid cases in South Africa have fallen again by 22 per cent compared to last week's figures, fuelling hopes that the country's Omicron wave is over.

South Africa, whose scientists detected the variant, recorded 21,099 new cases in the last 24 hours, down by nearly a quarter on the 26,976 infections confirmed last Wednesday.

A fifth fewer people were tested for the virus in the last 24 hours compared to the same period last week, but test positivity — the proportion of those tested who are infected — has been trending downwards for nine days.

Hospitalisations have also seen a slight decline, with more than 590 people admitted to hospitals across the country, down by four per cent in a week, data from the National Institute For Communicable Diseases (NICD), revealed.

But deaths – which lag two to three weeks behind the pattern seen in case numbers due to the delay in an infected person becoming seriously unwell – have risen.

A further 99 Covid-related deaths were recorded on Wednesday, compared to 54 recorded a week ago.

The falling case numbers come despite only 25 per cent of South Africans being double-jabbed and boosters not being dished out in the country.

The number of Covid patients on the country's wards is still rising, however. There wre 9,300 recorded yesterday up from 7,300 a week ago.

More patients are also in ICU and on ventilators, figures show, with 613 now being in emergency units across the country and 239 needing the machines to help them breathe.

Dr Groome said yesterday: 'All indications are that we've seen the end of the — that we've surpassed the peak of infections in Gauteng. This is encouraging and quite optimistic in terms of the decreasing trends in case numbers.

'But I think we really do need to be cognizant that… people are now traveling, and there may be changes in terms of the number of people that may be testing and so some of the lower numbers may be due to the holiday season.'

Can you build ‘super-immunity’ to Covid?

When even the losers are winners

Since its discovery in southern Africa last month, the Omicron variant of the coronavirus has spread across the globe, bringing with it fresh fear, new social restrictions and another chaotic and anxious Christmas season.

Britain has already recorded almost 91,000 confirmed cases of the strain so far and at least 18 deaths, according to the UK Health Security Agency, with those numbers expected to climb over the festive period.

However, much remains unknown about the highly-transmissible variant at this early stage in its development, with more clinical data still needed to determine precisely how it attacks and how it responds to our existing suite of vaccines, which have worked so well against previous strains and helped to keep hospitalisations and deaths low.

Early studies have suggested that a booster jab is crucial to holding off Omicron, which is why governments around the world have been encouraging their citizens to queue around the block for a third shot as a matter of urgency in recent weeks.

This week scientists reported that a booster shot provoked a response from the body’s immune system to the virus within two-to-three days, not weeks, as has previously been thought, swiftly activating the T and B memory cells responsible for hunting down infection and producing antibodies.

“The immunity generated after a booster jab will rise much quicker than the first immune response,” commented Gary McLean, a professor in molecular immunology at London Metropolitan University.

Another interesting new study at Oregon Health & Science University has since indicated that it might indeed be possible to develop “super-immunity” against Omicron in the case of sufferers contracting Covid-19 having had two doses of one of the vaccines.

The study examined the blood of 26 people who had experienced so-called “breakthrough” infections of Covid after being double-vaccinated and found that they developed antibodies that were as much as 1,000 per cent more effective and abundant, therein creating a form of super-immunity, according to the researchers.

While the vaccines are obviously intended to stop recipients from catching Covid in the first place, it is nevertheless still possible for the more pernicious strains like Delta and Omicron to slip past the body’s defences.

In the cases of the double-jabbed people examined as part of the study, that occurrence proved to be surprisingly beneficial by bolstering the robustness of their immune systems.

“You can’t get a better immune response than this,” said the study’s senior author, Fikadu Tafesse, an assistant professor of molecular microbiology and immunology at the university’s School of Medicine.

“These vaccines are very effective against severe disease. Our study suggests that individuals who are vaccinated and then exposed to a breakthrough infection have super-immunity.”

His colleague Marcel Curlin was even more optimistic about the study’s ramifications, commenting: “I think this speaks to an eventual end game.

“It doesn’t mean we’re at the end of the pandemic, but it points to where we’re likely to land: once you’re vaccinated and then exposed to the virus, you’re probably going to be reasonably well protected from future variants.

AstraZeneca Covid booster vaccine 'effective against omicron variant'

A three-dose course of AstraZeneca's Covid-19 vaccine is effective against the rapidly-spreading omicron variant, the pharmaceutical company said on Thursday, citing data from an Oxford University study.

Findings from the study, yet to be published in a peer-reviewed medical journal, match those from rivals Pfizer-BioNTech which have also found a third dose of their shots works against the variant.

The study on AstraZeneca's vaccine, Vaxzevria, showed that after a three-dose course of the vaccine neutralising levels against omicron were broadly similar to those against the virus's delta variant after two doses.

The company said that researchers at Oxford University who carried out the study were independent from those who worked on the vaccine with AstraZeneca.

"As we better understand omicron, we believe we will find that T-cell response provides durable protection against severe disease and hospitalisations," Mene Pangalos, the head of AstraZeneca's biopharmaceuticals research and development said, referring to a critical component of the immune system that responds to fight infection.

Antibody levels against omicron after the booster vaccine were higher than antibodies in people who had been infected with and recovered naturally from Covid-19, the Anglo-Swedish company added.

Although the early data is positive for the company, AstraZeneca said on Tuesday it was working with its partner Oxford University to produce a vaccine tailored for omicron, joining similar efforts from other vaccine-makers.

Two-thirds of new Covid hospital patients in England only tested positive AFTER being admitted for a different illness

In the two weeks to December 21, hospitals in England recorded 563 new coronavirus inpatients — the majority of which are believed to be Omicron now that the variant is the country's dominant stain.

But just 197 (35 per cent) were being primarily treated for Covid, with the remaining 366 (65 per cent) only testing positive after being admitted for something else.

Experts told MailOnline it was important to distinguish between admissions primarily for Covid so that rising numbers do not spook ministers into more social restrictions or scare the public from going to hospital.

England's incidental hospital cases are being driven by London, which has become the UK's Omicron hotspot and where admissions have been rising sharply.

Just over four in 10 new Omicron hospital patients in London were admitted for a different ailment, MailOnline's analysis suggests.

There were 523 more 'Covid admissions' resulting in an overnight stay in the two weeks to December 21, after Omicron became dominant in the capital earlier this month.

Admission rates for Covid in the capital are one factor ministers are keeping an eye on before potentially pulling the trigger on more curbs because London is considered to be a few weeks ahead of the rest of the country in its Omicron outbreak.

The rising number of so-called 'incidental cases' - people who are only diagnosed with the virus after going to the NHS for a different ailment - is in line with the picture in South Africa.

Studies in the epicentre Gauteng province have shown up to three-quarters of Omicron patients there were not admitted primarily for the virus.

Dr Raghib Ali, a Cambridge University clinical epidemiologist, said: 'If you've got very high prevalence of Omicron in the community then there is a higher chance anyone who comes to hospital for any reason, even people with broken legs, will have Covid.

Omicron Covid IS milder, three major studies confirm
Omicron is milder than Delta and far less likely to put someone in hospital, three major studies in England, Scotland and South Africa have confirmed.

One paper by 'Professor Lockdown' Neil Ferguson found the mutant strain was up to 45 per cent less likely to lead to hospitalisation than Delta, based on 300,000 people in England.

A similar study in Scotland found the risk of being hospitalised was 65 per cent less with Omicron than with Delta — but it was based on 15 hospitalised cases.

University of Edinburgh researchers said Omicron was as severe as Delta they would have seen around 47 people in hospital in Scotland, yet so far there are only 15.

The UK studies came after a major analysis of 160,000 infections in South Africa found an 80 per cent reduced risk of hospitalisation with the new variant compared to its predecessor.

All the evidence now points to Omicron being milder than former variants, confirming claims South African doctors have made for weeks.

But the researchers are still unsure if Omicron is intrinsically milder than past strains and they believe built-up natural and vaccine immunity is probably doing the heavy lifting.

Professor Ferguson — dubbed Professor Lockdown for gloomy modelling that spooked ministers into restrictions — said he was 'cautiously optimistic' on the back of all three studies.

Recorded case rates of Covid across the UK rose above 100,000 on Wednesday for the first time since the start of the pandemic.

Ministers have stressed the Government keeping new Covid data in constant review, with health minister Gillian Keegan saying yesterday: 'There is uncertainty. We can’t predict what the data is going to tell us before we’ve got the data.'

*************************************************

The Fickle ‘Science’ of Lockdowns

‘Follow the science” has been the battle cry of lockdown supporters since the Covid-19 pandemic began. Yet before March 2020, the mainstream scientific community, including the World Health Organization, strongly opposed lockdowns and similar measures against infectious disease.

That judgment came from historical analysis of pandemics and an awareness that societywide restrictions have severe socioeconomic costs and almost entirely speculative benefits. Our pandemic response, premised on lockdowns and closely related “non-pharmaceutical interventions,” or NPIs, represented an unprecedented and unjustified shift in scientific opinion from where it stood a few months before the discovery of Covid-19.

In March 2019 WHO held a conference in Hong Kong to consider NPI measures against pandemic influenza. The WHO team evaluated a quarantine proposal—“home confinement of non-ill contacts of a person with proven or suspected influenza”—less indiscriminate than the Covid lockdowns. They called attention to the paucity of data to support this policy, noting that “most of the currently available evidence on the effectiveness of quarantine on influenza control was drawn from simulation studies, which have a low strength of evidence.” The WHO team declared that large-scale home quarantine was “not recommended because there is no obvious rationale for this measure.”

A September 2019 report from Johns Hopkins University’s Center for Health Security reached a similar conclusion: “In the context of a high-impact respiratory pathogen, quarantine may be the least likely NPI to be effective in controlling the spread due to high transmissibility.” This was especially true of a fast-spreading airborne virus, such as the then-undiscovered SARS-CoV-2.

These studies drew on historical experience. A separate 2006 WHO study concluded that “forced isolation and quarantine are ineffective and impractical,” based on findings from the Spanish flu pandemic of 1918. It pointed to the example of Edmonton, Alberta, where “public meetings were banned; schools, churches, colleges, theaters, and other public gathering places were closed; and business hours were restricted without obvious impact on the epidemic.”

Using data from a 1927 analysis of the Spanish flu in the U.S., the study concluded that lockdowns were “not demonstrably effective in urban areas.” Only in isolated rural areas, “where group contacts are less numerous,” did this strategy become theoretically viable, but the hypothesis wasn’t tested. While the study found some benefits from smaller-scale quarantines of patients and their families during the 2003 SARS outbreak, it concluded that a fast-spreading disease, combined with “the presence of mild cases and possibility of transmission without symptoms,” would make these measures “considerably less successful.”

Medical historian John Barry, who wrote the standard account of the 1918 Spanish flu, concurred about the ineffectiveness of lockdowns. “Historical data clearly demonstrate that quarantine does not work unless it is absolutely rigid and complete,” he wrote in 2009, summarizing the results of a study of influenza outbreaks on U.S. Army bases during World War I. Of 120 training camps that experienced outbreaks, 99 imposed on-base quarantines and 21 didn’t. Case rates between the two categories of camps showed “no statistical difference.” “If a military camp cannot be successfully quarantined in wartime,” Mr. Barry concluded, “it is highly unlikely a civilian community can be quarantined during peacetime.”

A Johns Hopkins team reached similar conclusions in 2006: “No historical observations or scientific studies” could be found to support the effectiveness of large-scale quarantine. The scientists concluded that “the negative consequences of large-scale quarantine are so extreme . . . that this mitigation measure should be eliminated from serious consideration.” They rejected the modeling approach for relying too heavily on its own assumptions—circular reasoning that confuses a model’s predictions with observed reality.

Even at the outset of Covid-19, the unwisdom of lockdowns guided mainstream epidemiology. When the Wuhan region of China imposed harsh restrictions on Jan. 23, 2020, Anthony Fauci questioned the move. “That’s something that I don’t think we could possibly do in the United States, I can’t imagine shutting down New York or Los Angeles,” Dr. Fauci told CNN. He likely had the scientific literature in mind when he advised that “historically, when you shut things down, it doesn’t have a major effect.”

What caused the scientific community to abandon its aversion to lockdowns? The empirical evidence didn’t change. Rather, the lockdown strategy originated from the same sources the WHO had heavily deprecated in its 2019 report: speculative and untested epidemiological models.

The most influential model came from Imperial College London. In April 2020, the journal Nature credited the Imperial team led by Neil Ferguson for developing one of the main computer simulations “driving the world’s response to Covid-19.” The New York Times described it as the report that “jarred the U.S. and the U.K. to action.”

After predicting catastrophic casualty rates for an “unmitigated” pandemic, Mr. Ferguson’s model promised to bring Covid-19 under control through increasingly severe NPI policies, leading to event cancellations, school and business closures, and ultimately lockdowns. Mr. Ferguson produced his model by recycling a decades-old influenza model that was noticeably deficient in its scientific assumptions. For one thing, it lacked a means of even estimating viral spread in nursing homes.

The record of Mr. Ferguson’s previous models should have been a warning. In 2001 he predicted that mad cow disease would kill up to 136,000 people in the U.K., and he chastised conservative estimates of up to 10,000. As of 2018 the actual death toll was 178. His other missteps include predicted catastrophes for mad sheep disease, avian flu and swine flu that never panned out.

We evaluated the performance of Imperial’s Covid-19 predictions in 189 different countries at the first anniversary of their publication, March 26, 2021. Not a single country reached the predicted mortality rates of their “unmitigated spread” or even the “mitigation” model—the latter premised on social-distancing measures similar to what many governments enacted. Even Mr. Ferguson’s extreme “suppression” model, which assumed a strict lockdown curtailing public contacts by 75% for over a year, predicted more deaths than occurred in 170 of 189 countries. Imperial predicted up to 42,473 Covid deaths in Sweden under mitigation and 84,777 under uncontrolled spread. The country, which famously refused to lock down, had some 13,400 deaths in the first year.

Despite the failed predictions of these models, the Imperial team rushed a study to print in the journal Nature in June 2020, claiming that lockdowns had already saved 3.1 million lives. It remains the most heavily cited pro-lockdown study in epidemiology, despite its premature claims and its circular reliance on its own model to arrive at this figure.

In reality, lockdown stringency is a poor predictor of Covid-related mortality. Our examination of the 50 U.S. states and 26 countries found no discernible pattern connecting the two—a basic expectation if lockdowns performed as “the science” often insists.

So why did public-health authorities abandon their opposition to lockdowns? Why did they rush to embrace the untested claims of flawed epidemiological modeling? One answer appears in the Johns Hopkins study from 2019: “Some NPIs, such as travel restrictions and quarantine, might be pursued for social or political purposes by political leaders, rather than pursued because of public health evidence.”

Omicron IS milder, another study finds: New variant is 80 PER CENT less likely to lead to hospitalistion than Delta, according to real-world South African research

People who catch Omicron are 80 per cent less likely to be hospitalised than those who get Delta, a major study from South Africa suggests.

The real-world analysis, of more than 160,000 people, comes ahead of a similar UK Government report expected to show Britons are also less likely to be severely ill with the variant.

Omicron sufferers were also 70 per cent less likely to be admitted to ICU or put on a ventilator compared to those with Delta, according to the study led by South Africa's National Institute for Communicable Diseases (NICD).

South African doctors have insisted for weeks that Omicron is milder since raising the alarm about it on November 24 and accused the UK of panicking about Omicron.

But the researchers at the NICD who carried out the study, which has not been peer-reviewed yet, said it still doesn't answer whether Omicron is intrinsically weaker than Delta.

'It is difficult to disentangle the relative contribution of high levels of previous population immunity versus intrinsic lower virulence to the observed lower disease severity,' the researchers concluded.

Built-up immunity from three previous waves of the virus and vaccines are believed to be doing most of the heavy lifting in keeping patients out of hospital this time around.

Up to 70 per cent of South Africans are believed to have had Covid before and only around a quarter are double vaccinated, with boosters not widely available yet.

Omicron cases in South Africa yesterday fell for the fourth day in a row, while the UK's daily cases have been flat at around 90,000 for six days.

South Africa's hospital admissions are hovering at below 400 per day, on average, and dropped by 5 per cent in a week yesterday. In the UK, hospital rates have been mostly flat since late summer, with around 900 per day.

That's despite gloomy Government modelling warning that 1million Britons could be catching the virus daily by the end of the year.

Professor Paul Hunter, an expert in infectious diseases at the University of East Anglia, described the South African study as important and said it was the first properly conducted study to appear in pre-print form on the issue of Omicron versus Delta severity.

But Professor Hunter said its main weakness was that it compared Omicron data from one period with Delta data from an earlier period.

Omicron continues to fade in ground zero South Africa
Daily Covid cases in South Africa have fallen for the fourth day in a row as Omicron continues to fade in the variant's epicentre.

Data from the National Institute For Communicable Diseases (NICD) shows 15,424 South Africans tested positive in the last 24 hours, down by a third on the nearly 24,000 cases confirmed last Tuesday.

A fifth fewer people were tested for the first in the last 24 hours compared to the same period last week, but test positivity — the proportion of those tested who are infected — has been trending downwards for eight days.

But hospitalisations and deaths – which lag two to three weeks behind the pattern seen in case numbers due to the delay in an infected person becoming seriously unwell – have risen.

More than 630 people were hospitalised across the country, up only 5 per cent in a week but the highest daily number in the country's fourth wave.

The previous record was last Wednesday when 620 people were hospitalised. Meanwhile 35 deaths were recorded, a 46 per cent uptick on last Tuesday.

The falling case numbers come despite only 25 per cent of South Africans being double-jabbed and boosters not being dished out in the country.

The analysis was carried out by a group of scientists from the National Institute for Communicable Diseases (NICD) and major universities including University of the Witwatersrand and University of KwaZulu-Natal.

They used data from four sources: national COVID-19 case data reported to the NICD, public sector laboratories, one large private sector lab and genome data for clinical specimens sent to NICD from private and public diagnostic labs across the country.

They compared data on Omicron infections in October and November with data about Delta infections between April and November, all in South Africa.

A case was considered to be Omicron if the positive test did not detect part of the virus' cell - a tell-tale signal for Omicron due to its extensive mutations - and a high amount of the virus in the sample.

And a hospitalisation was linked with a positive case if a person was admitted to hospital between seven and 21 days of testing positive.

A patient was considered to have severe disease if they were admitted to ICU, required mechanical ventilation, received an oxygen treatment, fluid leaked into their lung or died.

Their study, which has not been peer-reviewed and was published on pre-print website medRxiv, found that among the 10,547 Omicron cases identified between October 1 and November 30, 261 (2.5 per cent) were admitted to hospital.

For comparison, among the 948 non-Omicron cases in the same period - almost all of which would have been Delta, which was behind 95 per cent of cases before Omicron emerged - 121 people were hospitalised (12.8 per cent).

After adjusting for other factors, the researchers said shows that those who caught Omicron had a 80 per cent lower risk of requiring hospital care.

Among those hospitalised with either strain in the nine-week period, the severity of illness was the same, with 317 of the 382 patients (83 per cent) discharged by December 21.

But comparing Omicron hospitalisations with Delta hospitalisations earlier this year, the scientists found Omicron patients were less likely to suffer from severe disease.

Since the beginning of the pandemic, 1,734 people in South Africa have been hospitalised whose test was genomically sequenced as either Alpha, Beta, Delta or Omicron.

The researchers also found that Omicron patients had much higher viral loads compared to Delta infections, echoing recent studies and data that the strain is more transmissible.

The researchers noted that around seven in 10 South Africans had already been infected with Covid by November when Omicon hit, while a quarter of its population is double-jabbed.

It is 'difficult to disentangle' how much previous infection and vaccines contribute to high levels of immunity against hospitalisation and severe illness from Omicron and how much is due to Omicron itself being less severe, the experts said.

Because there is no difference in Covid severity among Omicron and Delta patients hospitalised in the last two months, it is likely that the reduced severity of Omicron 'may be in part a result of high levels of population immunity' due to previous infection or vaccination, the researchers said.

It comes after a separate real-world study of 78,000 Omicron cases in South Africa found the risk of hospitalisation was a fifth lower than with Delta and 29 per cent lower than the original virus.

As a crude rate, Omicron is led to a third fewer hospital admissions than Delta did during its entire wave — 38 admissions per 1,000 Omicron cases compared to 101 per 1,000 for Delta.

The study also found two doses of Pfizer's vaccine still provide 70 per cent protection against hospital admission or death from Omicron, compared to 93 per cent for Delta.

While this is more protection than many scientists initially feared, it still leaves 30 per cent of people vulnerable to severe Omicron disease, four times as many as Delta.

Waning immunity from two Pfizer doses was found to offer just 33 per cent protection against Omicron infection, explaining why the country has seen a meteoric rise in case numbers.

Single vaccine for all COVID variants undergoing human trials

Scientists at the US Army’s Walter Reed Army Institute of Research are expected to announce the results of human trials of a single vaccine for all COVID variants in coming weeks.

Defense One reported that Dr Kayvon Modjarrad, director of Walter Reed’s infectious diseases branch, said Phase 1 of human trials of the “Spike Ferritin Nanoparticle” COVID-19 vaccine had positive results.

The trials tested the vaccine against Omicron and other variants, the US publication reported. The human trial followed successful animal trials completed earlier this year.

The new type of vaccine has been under development by the US Army since early 2020 when the Army lab received its first DNA sequencing of the COVID-19 virus.

Researchers believe the vaccine will potentially protect not only against the virus and variants responsible for the current COVID-19 pandemic, but also against other respiratory viruses such as Severe Acute Respiratory Syndrome, or SARS.

The “Spike Ferritin Nanoparticle” (SpFN) vaccine employs the common protein ferritin in the form of a soccer ball-shaped “platform”.

The platform has 24 “faces” onto which are attached replicas of the spike proteins used by some viruses, including coronaviruses, to break into cells.

Delivering spike replicas via vaccines teaches the immune system to recognise and attack them in case of infection.

In lab experiments, antibodies induced by the vaccine protected mice from what would otherwise have been lethal doses of the virus that causes COVID-19 and also of the virus that caused the 2003 SARS outbreak, researchers said on in Cell Reports on December 7.

“Presenting multiple copies of spike in an ordered fashion may be the key to inducing a potent and broad immune response,” said study leader Gordon Joyce of the Walter Reed Army Institute of Research in Silver Spring, Maryland said at the time.

The vaccine would remain stable at a wide range of temperatures, he said, making it especially useful in areas without specialised storage equipment.

Doctor Says He Was Fired for Trying to Treat COVID-19 Patients With Ivermectin

A Mississippi doctor said he was fired for attempting to treat COVID-19 patients with ivermectin, which is approved by the Food and Drug Administration (FDA) to treat parasites, although the hospital in question said he was not an employee but instead was an independent contractor.

Dr. John Witcher, an emergency room physician at the Baptist Memorial Hospital in Yazoo City, said was “told not to come back” after taking several COVID-19 patients off Remdesivir, which is approved by the FDA to treat the virus, and allowed them to use ivermectin.

“I was very surprised that I was basically told to not come back at the end of the day,” Witcher said on the Stew Peters podcast. “These patients were under my direct care, and so I felt like taking them off Remdesivir and putting them on ivermectin was the right thing to do at the time.”

Baptist Memorial told news outlets that Witcher “no longer practices medicine as an independent physician” at the Yazoo City facility, adding that he was an independent contractor, not an employee at the facility.

The hospital system said that it follows “the standards of care recommended by the scientific community and our medical team in the prevention and treatment of COVID-19” such as vaccines and monoclonal antibody treatments.

But Witcher said that he was working at the Baptist Memorial emergency room when three new COVID-19 patients arrived on Dec. 10. They were prescribed Remdesivir, but Witcher said that he has concerns about the drug.

“I was there at the hospital for three days straight in the ER and so I felt like this would be a good opportunity to try ivermectin on these inpatient patients that I had been following very closely and just see how well it worked,” Witcher remarked.

‘Negligible benefit’: Experts urge South Africa to end quarantine and contact tracing

Leading South African doctors advising the government’s Covid-19 response have called for quarantine and contact tracing to be stopped immediately, saying the measures are of “negligible public health benefit”.

The Ministerial Advisory Committee (MAC) on Covid-19, co-chaired by Professors Koleka Mlisana and Marian Jacobs, wrote to South African Health Minister Joe Phaahla on Thursday to argue that existing quarantine and contact tracing protocols were “outdated” and no longer effective containment measures.

The MAC pointed out that only a very small proportion of Covid-19 cases were detected through testing, as up to 84 per cent of cases were estimated to be asymptomatic.

“It stands to reason that if the vast majority of cases are not diagnosed, then the vast majority of case contacts are also not diagnosed,” Profs Mlisana and Jacobs wrote.

“This means that quarantining and contact tracing are of negligible public health benefit in the South African setting.”

South Africa introduced a 14-day quarantine period for “high risk” contacts of Covid-19 patients in early 2020. This was later reduced to 10 days.

“Since then, several changes to the Covid-19 situation have occurred,” they wrote. “The proportion of people with immunity to Covid-19 (from infection and/or vaccination) has risen substantially, exceeding 60-80 per cent in several serosurveys.

“We have learned more about the manner in which Covid-19 is spread, and also now have to contend with variants of concern whose epidemiology differs from that of the ancestral strains of SARS-CoV-2.

“Crucially, it appears that efforts to eliminate and/or contain the virus are not likely to be successful. Therefore, it is critical that the role of containment efforts like quarantine and contact tracing is re-evaluated.”

The MAC also said the definition of “high risk” contact – those who “had face-to-face contact or [were] in a closed space with a Covid-19 case for at least 15 minutes” – was “based on an outdated understanding of the transmission dynamics” of the virus.

“The definition concentrates on droplet spread while ignoring aerosol spread, which can occur over distances greater than 1-1.5 metres, and also does not require as close a temporal association with the index case,” they wrote.

“In addition, it ignores the increased intrinsic transmissibility of subsequent variants of concern compared to the ancestral strain, as well as the fact that pre-existing immunity (from vaccination and/or natural infection) further changes the transmission dynamics.”

The experts said quarantining was not feasible in many social settings, and had a “substantial economic and social burden”.

Those include “significantly depleting” staffing levels at healthcare facilities and other frontline roles such as police, and “significantly reducing economic and governmental activities due to high levels of staff absenteeism”.

“We propose that quarantining be discontinued with immediate effect for contacts of cases of Covid-19,” they wrote.

“This applies equally to vaccinated and non-vaccinated contacts. No testing for Covid-19 is required irrespective of the exposure risk, unless the contact becomes symptomatic.

“We further propose that contact tracing be stopped.

“Since quarantining of contacts of cases no longer serves a public health role, identifying contacts of Covid-19 cases equally serves very little role. In addition, contact tracing is impractical once the Covid-19 caseload rises, and is extremely burdensome in its use of human and financial resources.”

The letter came as Mr Phaahla announced that South Africa would remain under modified “level one” lockdown restrictions over Christmas, amid concerns over the spread of the Omicron variant, News24 reported.

Daily Covid cases in South Africa have fallen for the fourth day in a row as Omicron continues to fade in the variant's original centre

Data from the National Institute For Communicable Diseases (NICD) shows 15,424 South Africans tested positive in the last 24 hours, down by a third on the nearly 24,000 cases confirmed last Tuesday.

A fifth fewer people were tested for the first in the last 24 hours compared to the same period last week, but test positivity — the proportion of those tested who are infected — has been trending downwards for eight days.

But hospitalisations and deaths – which lag two to three weeks behind the pattern seen in case numbers due to the delay in an infected person becoming seriously unwell – have risen.

More than 630 people were hospitalised across the country, up only 5 per cent in a week but the highest daily number in the country's fourth wave.

The previous record was last Wednesday when 620 people were hospitalised. Meanwhile 35 deaths were recorded, a 46 per cent uptick on last Tuesday.

The falling case numbers come despite only 25 per cent of South Africans being double-jabbed and boosters not being dished out in the country.

It raises hopes that the UK's Omicron wave will also be short-lived, with Britain also having a layer of protection in its booster programme.

It comes as UK scientists wait for data on how deadly the Omicron surge will be, with uncertainties about how severe it is and how well vaccines protect against serious outcomes.

But promisingly, cases already appear to be plateauing in the UK, with around 90,000 daily infections recorded for the last six days.

That's despite gloomy Government modelling warning that 1million Britons could be catching the virus daily by the end of the year.

Boris Johnson today said no to Christmas curbs because there is 'no evidence' on Omicron to justify it.

The NICD confirmed 55,877 people had been tested across South Africa in the last 24 hours and 15,424 (27.6 per cent) tested positive.

And test positivity dropped to 27.6 per cent, which is the lowest figure recorded in 10 days and marks the eighth day of infection rates trending downwards.

Britain's daily Covid cases have plateaued for the fifth day in a row as an expert claimed that the Omicron wave may have peaked already.

There were 90,629 infections in the past 24 hours across the UK, up 52 per cent on last Tuesday's toll but down slightly on the figure yesterday — despite wild projections of up to a million daily infections by New Year,

Cases have remained flat since last Friday when they hit a peak of more than 93,000.

In London, which has become a hotbed for Omicron, the wave also appears to be slowing. A total of 20,491 cases were recorded in the capital today, down slightly on yesterday's tally of 22,750.

The slowing statistics may be behind Boris Johnson's decision not to bring in tougher restrictions before Christmas , with the Prime Minister claiming today there was 'not enough evidence to justify' them.

Gloomy Government modelling presented to ministers last week said the mutant variant was doubling every two days and was infecting up to 400,000 daily by the weekend.

Professor Paul Hunter, an infectious diseases expert at the University of East Anglia, told MailOnline that Mr Johnson had made the right decision because cases 'look like they've peaked'.

He said: 'It's not all doom and gloom, it does look like Omicron has stopped growing. The numbers over the last few days seem to have plateaued and maybe even be falling.

'It's a bit too soon to be absolutely sure about that, but if it is the case Boris Johnson will breathe a sigh of relief. We have to be a little bit careful because it's only a few days.

'And because we're getting closer to Christmas there is nervousness that people may not come forward for testing because they don't want to test positive and miss out on meeting relatives.

'Omicron overtook the other variants around December 14 so most of any changes from there on would be down to Omicron. So if it was still doubling every two days that would have shown and we should have been at 200,000 cases yesterday and certainly more than 200,000 cases today.

'But the fact it has been around 91,000 raises the point that it might actually have peaked. But it will probably take until at least Wednesday to get an idea of a day that is not affected by the weekend. But I am more optimistic than I was a few days ago.'

Some 3.3million people in the country have tested positive since the pandemic began, but the true figure will be many millions more as not everyone who catches the virus is tested.

The majority of the new cases were recorded in Kwazulu-Natal (4,009), followed by Western Cape (3,324), as the virus spreads away from the ground zero Gauteng.

The province, which is home to Johannesburg and is where Omicron was first spotted, recorded the third-most cases (3,316).

Meanwhile, 633 people were hospitalised in the last day, up 5.7 per cent in a week, bringing the country’s total number of hospitalisations since the pandemic began to 459,844.

A total of 9,023 people are currently receiving hospital care.

And a further 35 Covid deaths were recorded, up 45.8 per cent on last Tuesday when 24 fatalities were registered.

The data from the country suggests the outbreak is fading around a month after it was first detected, while ministers and scientists in the UK are panicking about the impact the wave will have over the coming weeks.

And the UK has strengthened its response to the variant through its booster campaign, while third jabs have not been dished out in South Africa and just 23 per cent of its population are vaccinated.

However, UK experts have warned Britain's older and denser population is more susceptible to a big and deadly outbreak.

England's chief medical officer Professor Chris Whity last week said he expected to see the UK's daily cases rise extraordinarily due to Omicron, but also 'come down faster than previous peaks', mirroring South Africa's experience with the strain.

Professor Whitty told MPs on the Health and Social Care Committee last week: 'I think what we will see with this is — and I think we’re seeing it in South Africa — is that the upswing will be very incredibly fast even if people are taking more cautious action.

He added: 'It’ll probably therefore peak really quite fast.

'My anticipation is it may then come down faster than previous peaks but I wouldn’t want to say that for sure.'

It comes as Britain's daily Covid cases have plateaued for the fifth day in a row as an expert claimed that the Omicron wave may have peaked already.

There were 90,629 infections in the past 24 hours across the UK, up 52 per cent on last Tuesday's toll but down slightly on the figure yesterday — despite wild projections of up to a million daily infections by New Year.

Cases have remained flat since last Friday when they hit a peak of more than 93,000.

In London, which has become a hotbed for Omicron, the wave also appears to be slowing. A total of 20,491 cases were recorded in the capital today, down slightly on yesterday's tally of 22,750.

Professor Paul Hunter, an infectious diseases expert at the University of East Anglia, told MailOnline that Mr Johnson had made the right decision because cases 'look like they've peaked'.

Nasal spray developed by Australian scientists STOPS cancer patients catching Covid with a bigger trial to find if it can be the next weapon to fight the pandemic

Another one of those evil nasal sprays. But this one uses a well recognized therapeutic ingredient so will be harder to dismiss

A trial for a nasal spray that has prevented cancer patients getting Covid-19 could be a new weapon to fight the pandemic.

Some 175 patients have tested the drug by taking daily doses of a nasal spray containing cancer drug interferon developed by scientists at the Peter MacCallum Cancer Centre and the Royal Melbourne Hospital.

None of the participants in the C-SMART trial have contracted Covid so far, despite several waves of the virus plunging Melbourne into six lockdowns.

Scientists are seeking more volunteers to take part in the free trial, which will be expanded to Austin and St Vincent's hospitals in Melbourne, along with Westmead Hospital in western Sydney.

Anyone with a past or current cancer diagnosis is eligible to take part in the four month trial.

Scientists hope the nasal spray will be an extra protection for vulnerable patients until better preventions are developed.

'We have not had any patient on the trial actually report back to us that they have developed Covid infection,' National Centre for Infections in Cancer director Professor Monica Slavin told the Herald Sun.

'But we have had about 10 per cent of people on the trial sending in a swab due to some sort of viral illness.

'We know that there are groups of patients, because of the immune system being suppressed, that don't make a good response to the vaccination.'

But it hasn't all been smooth sailing for the trial, which began a year ago.

Scientists were forced to press pause on the trial for five months earlier this year when access to chemicals and sending samples of the drug for testing were hampered by international border closures.

The expanded trial will determine whether the drug can also prevent other respiratory viral illnesses.

Studies have shown cancer patients make up 10 per cent of severe Covid-19 cases, and about 20 per cent of those who die from it, according to the trial's website.

They are also more likely to rapidly develop severe infections and be admitted to ICU compared to cases without cancer.

Moderna says booster significantly increases antibodies against Omicron

Moderna announced Monday that a booster shot of its COVID-19 vaccine significantly increases antibody levels against the highly-transmissible Omicron variant.

A 50 microgram jab — the authorized dose for a third shot — saw a 37-fold increase in neutralizing antibodies, the vaccine maker said.

Moderna also tested a 100 microgram booster dose, which increased antibody levels 83-fold. The first two shots of Moderna’s vaccine are both 100 micrograms.

The company said the higher booster dose was generally safe and well-tolerated, although there was a trend toward slightly more frequent adverse reactions.

Moderna CEO Stephane Bancel called the data “reassuring” but said it will continue to “rapidly advance an omicron-specific booster candidate into clinical testing in case it becomes necessary in the future.”

However, for now, the drugmaker said the current version of its vaccine – mRNA-1273 — will continue to be its “first line of defense against Omicron.”

“What we have available right now is 1273,” Dr. Paul Burton, Moderna’s chief medical officer, told Reuters.

“It’s highly effective, and it’s extremely safe. I think it will protect people through the coming holiday period and through these winter months, when we’re going to see the most severe pressure of Omicron,” he added.

The data, which has not yet been peer-reviewed, tested blood from 20 booster recipients with each dose against a pseudovirus engineered to resemble the Omicron variant, the company said.

Antibody levels were measured on day 29 post-boost.

Burton said it would be up to governments and regulators to assess whether they want the enhanced level of protection that a 100 microgram dose might provide.

US regulators authorized Moderna’s 50 microgram booster in October.

Ancient Greek drug used to treat gout could reduce the risk of death from Covid-19 by as much as 50 per cent, study claims

A drug used to treat gout could hold the potential to cut the risk of death from Covid-19 by as much as 50 per cent, a new study claims.

Colchicine is an ancient drug derived from the Colchicum family of plants, which was first used for its special healing properties by the ancient Greeks.

It began to be widely used from about the first century AD as a treatment for gout and other inflammatory conditions, and is one of a few medicines that have survived into modern times, according to experts from the Hebrew University of Jerusalem.

Four controlled studies, involving 6,000 coronavirus patients, have been published into the effects of the drug, with each showing a 'clear benefit' from its use.

The Israeli researchers analysed the studies, finding 'significant improvement in severe coronavirus indices and, most importantly, there was a decrease in mortality by about 50 per cent compared to those who were not treated with colchicine.'

This is an important discovery, as the drug is cheap and requires just half a milligram dose per day, according to the researchers.

However, previous studies have found mixed results on the use of the drug, with some finding a significant benefit, as was the case here, and others finding none.

An Indian study from November found no benefit to using the drug to treat Covid-19.

What is colchicine? The 30p drug used to tackle gout

Colchicine is used to treat and prevent systemic inflammation, a feature of gout and the worst cases of coronavirus

Colchicine is a medicine for treating inflammation and pain. The pills are typically prescribed to treat flare-ups or attacks of gout

It is also used to prevent increased flare-ups of gout when a patient first starts on a medicine like allopurinol – taken to manage the condition in the long term.

Colchicine is also prescribed to prevent flare-ups of symptoms of familial Mediterranean fever (FMF) – an inherited inflammatory condition.

The usual dose for gout is one 0.5mg tablet, taken two to four times a day. Patients are advised to avoid grapefruit and grapefruit juice while taking colchicine.

Some patients find it is gentler on their stomach if they take the tablets with or after food.

It is not usually recommended in pregnancy or when breastfeeding.

For this new research, Prof Ami Schattner came at it from a different perspective, focusing on all patients treated in controlled trials with the ancient drug for any purpose over the past 20 years, rather than just treated for Covid-19.

Of the studies he reviewed, four focused on coronavirus and involved 6,000 patients, finding each saw a 'significant improvement' when using the drug.

Schattner says colchicine working to improve the outcome of Covid-19 patients is 'an important discovery that could significantly contribute to improving the morbidity and mortality of many patients, if confirmed in further studies.'

This is because, as well as being cheap, it is well-tolerated by patients with minimal side effects such as bouts of diarrhoea in 10 per cent of patients.

The studies used by the Israeli team were conducted around the world, including in Canada, Greece, Spain and Brazil.

They were all double-blind placebo studies, which make them more accurate, according to Schattner.

Further randomised trials are needed, involving the drug and Covid-19 patients, to confirm the results of this 'preliminary study', said Schattner.

He said that it is likely going to lead to an expansion of the use of low-dose colchicine in the treatment of coronavirus patients, and says there is 'no reason' that couldn't start now.

In November, an Indian research team from GMERS Medical College Gotri in Gujarat performed a meta-analysis of six studies that tested colchicine's ability to prevent severe cases of the virus.

'Colchicine does not reduce the risk of mortality, need for ventilatory support, intensive care unit admission or length of hospital stay among patients with Covid-19,' researchers wrote.

'There is no additional benefit of adding colchicine to supportive care in the management of patients with Covid-19.'

Four of the studies also researched whether the drug could reduce Covid-19 related hospital stays.

The combined results found no difference in mortality rates among people who used colchicine and those that did not.

In March a large British trial halted enrolments to test colchicine as a potential treatment for patients hospitalised with Covid-19.

This was after a sub-study of the trial found that the medication did not have any effect on the patients.

However, Schattner says his results are 'very promising' and worth exploring further.

'Even though initial data on the effect of colchicine on coronavirus patients is very promising, more patients need to be in randomised controlled trials,' Schattner told the Jerusalem Post.

'But that would not prevent me from using the drug already in patients with high risk, to hopefully lower their chances of developing severe disease.

'The drug is low-cost for the patients and the community,' he said. 'By using it in corona patients, we have nothing to lose and much to gain.'

A few gout drugs have been pointed to as potential Covid-19 treatments since the pandemic began.

Drugs used to treat gout often have anti-inflammatory properties, which can also reduce some of the side-effects of Covid-19.

Previous studies identified colchicine as a drug that could reduce inflammation related to Covid-19 and help patients.

Another anti-inflammatory drug used to treat gout, probenecid, has also showed a promising ability to combat Covid-19, though further research is needed.
