Rising number of breakthrough Delta infections among fully vaccinated
Chicago: A quarter of Los Angeles residents who caught COVID from May to July this year as the Delta variant surged were fully vaccinated.
The data, published in the US Centres for Disease Control and Prevention’s weekly report on death and disease, shows an increase in “breakthrough” infections among those who had both doses of a coronavirus vaccine.
The centre is relying on data from cohorts, such as the Los Angeles County study, to determine whether Americans need a third dose of COVID-19 vaccines to increase protection. Government scientists last week laid out a strategy for booster doses beginning on September 20, pending reviews from the US Food and Drug Administration and the CDC.
While a quarter of the COVID infections in the Los Angeles study were in the fully vaccinated, fewer than one in 20 was hospitalised.

The new data released on Tuesday involved more than 43,000 reported infections among Los Angeles County residents aged 16 and older. Of them, 10,895, or 25.3 per cent occurred in fully vaccinated persons, and 1431, or 3.3 per cent, were in partially vaccinated persons. The majority of infections, however, were among the unvaccinated: 30,801 cases, or 71.4 per cent of the cohort.
The vaccines did, however, protect individuals from more severe symptoms. According to the study, only 3.2 percent of fully vaccinated individuals who tested positive for coronavirus were hospitalised, just 0.05 per cent were admitted to an intensive care unit and 0.25 per cent were placed on a ventilator.
Among the unvaccinated who caught COVID, 7.5 per cent were hospitalised, 1.5 per cent were admitted to an intensive care unit and 0.5 per cent required breathing support with a mechanical ventilator.
In addition to the LA County data, the CDC on Tuesday released an update on a study of healthcare workers that showed a significant drop in vaccine effectiveness among vaccinated frontline workers in eight states who became infected with the coronavirus.
The effectiveness of COVID-19 vaccines among healthcare workers declined to 66 per cent after the Delta variant became dominant, compared with 91 per cent before it arose, according to the report.
The vaccines are still protective, the centre said, and the finding must be interpreted with caution, as vaccine effectiveness might wane over time and the estimates of efficacy were imprecise.
“Although these interim findings suggest a moderate reduction in the effectiveness of Covid-19 vaccines in preventing infection, the sustained two-thirds reduction in infection risk underscores the continued importance and benefits of Covid-19 vaccination,” researchers wrote in the agency’s Morbidity and Mortality Weekly Report.
The findings echo earlier evidence from Israel and the UK suggesting COVID-19 vaccines lost some potency in preventing infections over time as the Delta variant spread.
The observational study tracked more than 4,000 health-care workers, first responders, and other front-line personnel in eight locations across six states from December 2020 to August 2021. They were tested weekly for COVID-19 infection, and about 83 per cent were vaccinated.
About two-thirds of those vaccinated had received the Pfizer shot, 2 per cent received Johnson & Johnson’s, and the rest received the Moderna vaccine.

Q & A on Delta
The rise of Delta, which is far more easily transmitted from person to person than previous strains of the virus, has made going out in public riskier. That’s one reason why the Centers for Disease Control and Prevention (CDC) recently changed its masking recommendations—it now advises vaccinated people in areas with high levels of virus to wear a mask indoors. Figuring out when to take risks and when not to is largely a matter of individual circumstance and preference. For instance, people with weakened immune systems should be more cautious than those with robust immune systems. Here are answers to some other common questions:
Q: How great is the risk of getting sick if you’ve gotten the vaccine?
It depends on the vaccine. A study published in the New England Journal of Medicine in July showed that the twoshot Pfizer mRNA vaccine was 88 percent effective in preventing illness due to the Delta variant, down from 93.7 percent for the Alpha variant. The Moderna mRNA shot is thought to offer similar protection. The study found that the Astra-Zeneca vaccine was 67 percent effective against Delta, as opposed to 74.5 for Alpha.
Q: If vaccinated people can still be infected, should they worry about being able to transmit the virus to others?
Yes, but not as much as unvaccinated people should. According to internal CDC documents recently obtained by The Washington Post, vaccinated people who have been infected with the Delta variant may spread the virus as efficiently as unvaccinated people who are infected. Delta tends to concentrate in the nose and throat, which is why the C.D.C. wants everyone to mask up. However, because vaccinated people tend to have stronger immune responses to the virus, they are probably contagious for only a short time—though this scenario has not been studied rigorously.
Q: Can vaccinated people who show symptoms develop long-haul COVID-19?
Little is known about longhaul COVID. In a recent study of health care workers, 19 percent of vaccinated people who got sick still had symptoms after six weeks. Keep in mind that this is only one study with relatively few participants, so firm conclusions will have to wait for more data.
Q: When will children under the age of 12 be eligible for a shot?
Current estimates range from as little as a month or two to well into 2022. On the far side of the range: FDA officials say they expect children under 12 to be eligible for vaccination by midwinter, after another four to six months of clinical trials. Pfizer, though, is more optimistic. In June, it began a study of 4,500 kids aged 5-to-11 in the U.S., Poland, Finland and Spain and hopes to have enough data collected by September to ask officials for an emergency use authorization.
Q: How do doctors determine which variant you have?
COVID-19 tests don’t identify variants. To find out how prevalent a variant is, the CDC takes samples, identifies them by sequencing their genetic material and then estimates what proportion of infections a given variant accounts for.
Q: Are the symptoms different between the variants?
Symptoms from many variants are similar to those of the original virus—fever, dry cough, shortness of breath. However, Delta can also manifest more like a bad cold, with a runny nose, sore throat and headache. Recently, reports of loss of smell and taste have become less common, according to the Zoe Covid Symptom study.
Q: When does the immunity from the vaccine start to wane? Is it the same for mRNA vaccines and others?
Pfizer recently said that the effectiveness of its mRNA vaccine declines to 84 percent about four to six months after the second shot, based on an internal study that has not yet been peer reviewed. A study in the journal Nature suggested that the mRNA vaccines have potentially long-lasting immunity.
Q: Will everyone eventually need booster shots? Or only those who are elderly and/or immunocompromised?
It depends in part on what kind of variants arise in the future. For now, experts do not foresee a need for most healthy vaccinated people to get booster shots, but that could change. Public health officials have suggested that those with weakened immune systems may need to get boosters this winter.
Q: Is it safe to go back into an office to work?
Safe is a relative term. It depends on an individual’s health, circumstances and tolerance for risk. In an office where everybody is vaccinated and virus levels in the community are low, the risk is small. In an office where many people are unvaccinated and virus levels are high, the risk can be many times higher. The risk for an unvaccinated person is always higher than for a vaccinated person. Vaccinated people who are immunocompromised or are caring for someone who is vulnerable at home may want to keep their potential exposure to the virus as low as possible—which means avoiding crowded, poorly ventilated rooms and wearing masks when indoors with others who may not be vaccinated. Because the Delta variant is so highly transmissible, the CDC now recommends mask wearing for everyone in indoor settings in regions where virus levels are high.
Q: In light of the Delta variant, should we be rethinking resuming regular activities like going to restaurants, sporting events, concerts, flying on planes, etc.?
Most vaccines still offer excellent protection. However, the risk goes up with exposure to the virus—and the Delta variant, with its high transmissibility, has ratcheted up the risk for all activities. Risk tolerance varies from one person to the next, but in general it’s a good idea to be aware of situations that are likely to bring you into contact with high levels of virus. Crowded, stuffy bars are riskier than spacious, well ventilated restaurants. Airplanes usually have good ventilation, but you have to worry about that unmasked, unvaccinated person sitting next to you. If in doubt, wear a mask.
Q: If you’ve already had COVID-19 with mild symptoms, what are the benefits of getting the vaccine?
One big benefit of vaccination is that it reduces the overall level of virus in a population, which makes everyone safer. Some studies also suggest that vaccines provide better protection for longer than natural infection. For instance, a study in China, recently published in The Lancet, showed that only 40 percent of people who had gotten COVID-19 carried antibodies to the coronavirus months later.
Q: If you’ve already had COVID-19 and are getting the vaccine, do you need to get both shots?
Yes. A recent study in the U.K., published in Nature, found that a single shot of the Pfizer vaccine reduced illness from the Delta variant by 33 percent. Two weeks after the second shot, that protection rose to 88 percent.

Those Anti-Covid Plastic Barriers Probably Don’t Help and May Make Things Worse
Covid precautions have turned many parts of our world into a giant salad bar, with plastic barriers separating sales clerks from shoppers, dividing customers at nail salons and shielding students from their classmates.
Intuition tells us a plastic shield would be protective against germs. But scientists who study aerosols, air flow and ventilation say that much of the time, the barriers don’t help and probably give people a false sense of security. And sometimes the barriers can make things worse.
Research suggests that in some instances, a barrier protecting a clerk behind a checkout counter may redirect the germs to another worker or customer. Rows of clear plastic shields, like those you might find in a nail salon or classroom, can also impede normal air flow and ventilation.
Under normal conditions in stores, classrooms and offices, exhaled breath particles disperse, carried by air currents and, depending on the ventilation system, are replaced by fresh air roughly every 15 to 30 minutes. But erecting plastic barriers can change air flow in a room, disrupt normal ventilation and create “dead zones,” where viral aerosol particles can build up and become highly concentrated.
“If you have a forest of barriers in a classroom, it’s going to interfere with proper ventilation of that room,” said Linsey Marr, professor of civil and environmental engineering at Virginia Tech and one of the world’s leading experts on viral transmission. “Everybody’s aerosols are going to be trapped and stuck there and building up, and they will end up spreading beyond your own desk.”
There are some situations in which the clear shields might be protective, but it depends on a number of variables. The barriers can stop big droplets ejected during coughs and sneezes from splattering on others, which is why buffets and salad bars often are equipped with transparent sneeze guards above the food.
But Covid-19 spreads largely through unseen aerosol particles. While there isn’t much real-world research on the impact of transparent barriers and the risk of disease, scientists in the United States and Britain have begun to study the issue, and the findings are not reassuring.
A study published in June and led by researchers from Johns Hopkins, for example, showed that desk screens in classrooms were associated with an increased risk of coronavirus infection. In a Massachusetts school district, researchers found that plexiglass dividers with side walls in the main office were impeding air flow. A study looking at schools in Georgia found that desk barriers had little effect on the spread of the coronavirus compared with ventilation improvements and masking.
Before the pandemic, a study published in 2014 found that office cubicle dividers were among the factors that may have contributed to disease transmission during a tuberculosis outbreak in Australia.
British researchers have conducted modeling studies simulating what happens when a person on one side of a barrier — like a customer in a store — exhales particles while speaking or coughing under various ventilation conditions. The screen is more effective when the person coughs, because the larger particles have greater momentum and hit the barrier. But when a person speaks, the screen doesn’t trap the exhaled particles — which just float around it. While the store clerk may avoid an immediate and direct hit, the particles are still in the room, posing a risk to the clerk and others who may inhale the contaminated air.
“We have shown this effect of blocking larger particles, but also that the smaller aerosols travel over the screen and become mixed in the room air within about five minutes,” said Catherine Noakes, professor of environmental engineering for buildings at the University of Leeds in England. “This means if people are interacting for more than a few minutes, they would likely be exposed to the virus regardless of the screen.”
Dr. Noakes said erecting barriers may seem like a good idea but can have unintended consequences. She conducted a study published in 2013 that looked at the effect of partitions between beds in hospitals. The study showed that while some people were protected from germs, the partitions funneled the air in the room toward others.
So while a worker behind a transparent barrier might be spared some of the customer’s germs, a worker nearby or customers in line could still be exposed. Dr. Noakes said most screens she has seen are “poorly positioned and are unlikely to be of much benefit.”
“I think this may be a particular problem in places like classrooms where people are present for longer periods of time,” Dr. Noakes said. “Large numbers of individual screens impede the airflow and create pockets of higher and lower risk that are hard to identify.”
To understand why screens often have little effect on protecting people from aerosol particles, it helps to think about exhaled breath like a plume of cigarette smoke, Dr. Marr said.
“One way to think about plastic barriers is that they are good for blocking things like spitballs but ineffective for things like cigarette smoke,” Dr. Marr said. “The smoke simply drifts around them, so they will give the person on the other side a little more time before being exposed to the smoke. Meanwhile, people on the same side with the smoker will be exposed to more smoke, since the barriers trap it on that side until it has a chance to mix throughout the space.”
Most researchers say the screens most likely help in very specific situations. A bus driver, for instance, shielded from the public by a floor-to-ceiling barrier is probably protected from inhaling much of what passengers are exhaling. A bank cashier behind a wall of glass or a clerk checking in patients in a doctor’s office may be at least partly protected by a barrier.
A study by researchers with the National Institute for Occupational Safety and Health in Cincinnati tested different sized transparent barriers in an isolation room using a cough simulator. The study, which hasn’t yet been peer-reviewed, found that under the right conditions, taller shields, above “cough height,” stopped about 70 percent of the particles from reaching the particle counter on the other side, which is where the store or salon worker would be sitting or standing.
But the study’s authors noted the limitations of the research, particularly that the experiment was conducted under highly controlled conditions. The experiment took place in an isolation room with consistent ventilation rates that didn’t “accurately reflect all real-world situations,” the report said.
The study didn’t consider that workers and customers move around, that other people could be in the room breathing the redirected particles and that many stores and classrooms have several stations with acrylic barriers, not just one, that impede normal air flow.
While further research is needed to determine the effect of adding transparent shields around school or office desks, all the aerosol experts interviewed agreed that desk shields were unlikely to help and were likely to interfere with the normal ventilation of the room. Depending on the conditions, the plastic shields could cause viral particles to accumulate in the room.
“If there are aerosol particles in the classroom air, those shields around students won’t protect them,” said Richard Corsi, the incoming dean of engineering at the University of California, Davis. “Depending on the air flow conditions in the room, you can get a downdraft into those little spaces that you’re now confined in and cause particles to concentrate in your space.”
Aerosol scientists say schools and workplaces should focus on encouraging workers and eligible students to be vaccinated, improving ventilation, adding HEPA air filtering machines when needed and imposing mask requirements — all of which are proven ways to reduce virus transmission.
The problem, experts say, is that most people in charge of erecting barriers in offices, restaurants, nail salons and schools are not doing so with the assistance of engineering experts who can evaluate air flow and ventilation for each room.
People shouldn’t panic when they see transparent barriers, but they shouldn’t view them as fully protective, either. Workers and students who have transparent shields around them should continue to wear a mask to lower risk, Dr. Corsi said.
“Air flow in rooms is pretty complicated,” Dr. Corsi said. “Every room is different in terms of the arrangement of the furniture, the height of the walls and ceilings, the vents, where the book shelves are. All of these things have a huge impact on the actual flow and air distribution in a room because every classroom or office space is different.”

Covid antibody treatment lowered risk of symptomatic disease by 77% in trial
A new coronavirus antibody treatment developed by drugs giant AstraZeneca and aimed at people who cannot be vaccinated reduced the risk of developing symptomatic disease by 77%, the company said.
The results of the Provent phase III pre-exposure prophylaxis trial showed there were no cases of severe Covid or Covid-related deaths in those treated with the “antibody cocktail” AZD7442, AstraZeneca said on Friday.
The study of more than 5,000 adults found AZD7442, a combination of two long-acting antibodies, also reduced the risk of developing symptomatic Covid-19 by 77% compared to a placebo.
In the placebo group there were three cases of severe coronavirus which included two deaths, the company added.
The drugs company said the antibody combination, which is delivered through an injection to the muscle, could give people up to 12 months of protection from Covid-19.
It is the first non-vaccine antibody combination modified to provide potentially long-lasting protection that has demonstrated prevention of Covid-19 in a clinical trial, AstraZeneca added.
Sir Mene Pangalos, executive vice-president of biopharmaceuticals R&D at AstraZeneca, said: “We need additional approaches for individuals who are not adequately protected by Covid-19 vaccines.
“We are very encouraged by these efficacy and safety data in high-risk people, showing our long-acting antibody combination has the potential to protect from symptomatic and severe disease, alongside vaccines.
“We look forward to sharing further data from the AZD7442 phase III clinical trial programme later this year.”
More than 75% of participants in the trial had co-morbidities and other characteristics that are associated with an increased risk of severe Covid-19 or cause a reduced immune response to vaccination, AstraZeneca said.
These include those with immunosuppressive disease or taking immunosuppressive medications, diabetes, severe obesity or cardiac disease, chronic obstructive pulmonary disease, chronic kidney and chronic liver disease.
The long-acting antibodies were well tolerated and preliminary analyses showed adverse events were balanced between the placebo and AZD7442 groups, AstraZeneca added.
AZD7442 could be an important tool in our arsenal to help people who may need more than a vaccine to return to their normal lives
Myron J Levin, principal investigator on the trial
The participants will continue to be monitored for 15 months, the company said.
AstraZeneca also said that preliminary “in vitro” findings from investigators at Oxford University and Columbia University show AZD7442 neutralises recent emergent Covid strains, including the Delta variant.
Myron J Levin, professor of paediatrics and medicine at the University of Colorado School of Medicine and principal investigator on the trial, said: “The Provent data show that one dose of AZD7442, delivered in a convenient intramuscular form, can quickly and effectively prevent symptomatic Covid-19.
“With these exciting results, AZD7442 could be an important tool in our arsenal to help people who may need more than a vaccine to return to their normal lives.”
AstraZeneca said it will prepare regulatory submissions of the data for health authorities for potential emergency use authorisation or conditional approval of AZD7442.
Professor Penny Ward, visiting professor in pharmaceutical medicine at King’s College London, said the new treatment could be a very important option for patients at high risk from Covid who have responded poorly to vaccination or who must take immune-suppressing treatment for other diseases.
It could potentially be game changing for these individuals, who are currently being advised to continue to shield despite being fully vaccinated
Professor Penny Ward, King’s College London
She added: “Indeed it could potentially be game changing for these individuals, who are currently being advised to continue to shield despite being fully vaccinated.
“Despite the success of vaccination some individuals do not respond as well and remain at higher risk of disease, hospitalisation and death. Prophylaxis with passive antibody therapy can help these folks further and reduce morbidity and mortality in this important population subset.
“They can be used to protect people while they undergo cancer treatment, for example.”
But Prof Ward said while the initial data was “encouraging” full publication of the results was need to understand the merits of the product and how to use it “most effectively” in practice.
Helen Rowntree, director for research, services and engagement for Blood Cancer UK, said the Medicines and Healthcare products Regulatory Agency (MHRA) needed to urgently assess the drug for approval for use in the UK.
If approved, the Government needs to draw up plans for giving it to people with blood cancer as quickly as possible, she added.
Ms Rowntree said: “This is great news for people with blood cancer because while their weakened immune systems mean they are less likely to respond to vaccines, this treatment does not rely on the immune system to produce antibodies to fight off the virus.
“This means that this may even be the game changer that potentially gives people with blood cancer the same kind of protection from Covid as the vaccines are already giving people who don’t have blood cancer.”

‘Centrist Chad’ Explains Vaccine Hesitancy in the Most Epic Thread You’ll Read All Year
Saturday, August 21, 2021
Pfizer effectiveness declines faster than AZ, new study suggests
The effectiveness of the Pfizer-BioNTech vaccine against Covid-19 declines faster than that of the AstraZeneca jab, according to a new study published on Thursday.
“Two doses of Pfizer-BioNTech have greater initial effectiveness against new Covid-19 infections, but this declines faster compared with two doses of Oxford-AstraZeneca,” researchers at Oxford University said.
The study, which has not been peer reviewed, is based on the results of a survey by Britain’s Office for National Statistics that carried out PCR tests from December last year to this month on randomly selected households.
It found that “the dynamics of immunity following second doses differed significantly” between Pfizer and AstraZeneca, according to the university’s Nuffield Department of Medicine.
Pfizer had “greater initial effectiveness” but saw “faster declines in protection against high viral burden and symptomatic infection”, when looking at a period of several months after full vaccination, although rates remained low for both jabs.
“Results suggest that after four to five months effectiveness of these two vaccines would be similar,” the scientists added, while stressing that long-term effects need to be studied.
The study’s findings come as Israel is administering booster shots, after giving 58 per cent of the population two shots of the Pfizer jab.
The United States is also set to offer booster vaccines to boost antibody levels following concerns over declining effectiveness of the Pfizer and Moderna vaccines.
The Oxford research also found that protection was higher among those who had already been infected with the virus.
The study examined two groups of more than 300,000 people over 18, first during the period dominated by the Alpha variant, which emerged in Kent, southeast England, and secondly from May 2021 onwards, when the Delta variant has been dominant.
It confirmed that vaccines are less effective against Delta, which was first seen in India.
The AstraZeneca vaccine is the most widely offered in the UK, while those under 40 are offered Pfizer or Moderna due to blood clotting concerns.

Evidence mounts that people with breakthrough infections can spread Delta easily
A preliminary study has shown that in the case of a breakthrough infection, the Delta variant is able to grow in the noses of vaccinated people to the same degree as if they were not vaccinated at all. The virus that grows is just as infectious as that in unvaccinated people, meaning vaccinated people can transmit the virus and infect others.
Previous studies in hospitals in India; Provincetown, Massachusetts; and Finland have also shown that after vaccine breakthrough infections with Delta, there can be high levels of virus in people’s nose whether they are vaccinated or not. The next logical step was to determine whether vaccinated people could shed infectious virus. Many experts suspected they did, but until this study it hadn’t been proven in the lab.
“We're the first to demonstrate, as far as I'm aware, that infectious virus can be cultured from the fully vaccinated infections,” says Kasen Riemersma, a virologist at University of Wisconsin who is one of the authors of the study.
“Delta is breaking through more preferentially after vaccines as compared to the non-Delta variants” because it’s extremely infectious and evades the immune response, says Ravindra Gupta, a microbiologist at University of Cambridge. Gupta’s lab was one of the first to document that fully vaccinated healthcare workers could get infected with Delta and had high levels of virus in their noses.
If the Wisconsin study finding holds up, then people with breakthrough infections—many of whom do not develop COVID symptoms—can unknowingly spread the virus. “It [is] an alarming finding,” explains Katarina Grande, a public health supervisor and the COVID-19 Data Team Lead of Madison & Dane County, who led the study.
What concerns Eric Topol, the founder and director of the Scripps Research Translational Institute, is that fully vaccinated individuals who are infected with the Delta variant can transmit the virus and this can happen at a higher rate than previous strains in the days before symptoms, or in the absence of symptoms. “Which is why masks and mitigation measures are important, even for people [who are] vaccinated,” he says.
Studies like these highlight that transmission of the Delta variant can be much higher that currently estimated, according to Ethan Berke, chief public health officer of the UnitedHealth Group. Berke’s research has shown that frequent testing with rapid results, even if preliminary, can be very effective in curtailing the COVID-19 pandemic. Berke was not involved in the Wisconsin study.
“Even though the study was based on one region, it offers important insight into how people can spread the virus to others whether they’re fully vaccinated or not. This sort of insight, especially as it’s tested and refined, is incredibly helpful as organizations develop policies around testing, social distancing, and vaccinations,” Berke says.
How do we know the virus in the sample is infectious?
To test for SARS-CoV-2, the scientists employed a measurement called threshold cycle (Ct) that uses glowing dyes to reveal the quantity of viral RNA in the nose.
“SARS-CoV-2 virus infects nose and upper airway. It is very difficult to get a very high level of antibodies for long periods of time in that area. The immune system is not really designed to put high levels of antibodies at those sites,” Gupta says.
Ct values correlate with the viral load, which is the number of viral particles present in the body. When the quantity of virus passes a certain threshold, researchers expect an infected person to shed SARS-CoV-2 and potentially infect others. The Wisconsin study analyzed the nasal swabs from 719 cases of unvaccinated and fully vaccinated people who had all tested positive and found that 68 percent of the studied breakthrough patients had very high viral loads. High viral load is a sign that the virus is replicating, Gupta says.
To discover whether the nasal swabs had infectious virus, the Wisconsin researchers grew virus from 55 patient samples (from both vaccinated and unvaccinated people who tested positive) in special cells prone to SARS-CoV-2 infection. Grande’s team detected infectious virus in nearly everyone: from 88 percent of unvaccinated individuals and 95 percent of vaccinated people.
“We put the samples onto cells, and the cells died when they got infected. And so that clearly demonstrates that there is virus there, and that it's infectious,” Riemersma explains.
If vaccinated people can still produce a lot of infectious viruses, it means they can spread the virus as easily as those who are not vaccinated.

July inflation report is bad news for consumers — again
And it's even worse for savers. Inflation can reduce your savings to worthlessness. And the main cause is excessive government spending
Since President Joe Biden entered the Oval Office, inflation in America has become a persistent problem. In fact, inflation has steadily risen from 1.7% in January to 5.4% in both June and July.
Sadly, this is bad news for consumers, who are more than aware that their money isn’t going as far as it did just a few months ago.
Per the Bureau of Labor Statistics , “The all items index rose 5.4 percent for the 12 months ending July, the same increase as the period ending June. The index for all items less food and energy rose 4.3 percent over the last 12 months, while the energy index rose 23.8 percent. The food index increased 3.4 percent for the 12 months ending July, compared to a 2.4-percent rise for the period ending June.”
Yet, most significantly, “The energy index increased 1.6 percent in July after rising 1.5 percent in June. All the major energy component indexes increased over the month. … The energy index rose 23.8 percent over the past 12 months. The gasoline index rose 41.8 percent since July 2020. The index for natural gas rose 19.0 percent over the last 12 months, while the index for electricity increased 4.0 percent.”
Those are some startling statistics, especially if you are on a fixed income (like most seniors) or a family in the working class just trying to make ends meet.
As the data show, the cost of almost everything is increasing rapidly. Yet, wages remain basically stagnant. In June , hourly wages increased by a microscopic 0.3%.
Inflation, by and large, is much more of a problem for those in the working class because a high proportion of their income is spent on the basics, such as gasoline, food, and home energy costs.
When the prices of these staple items increase substantially (as they have over the past seven months) and wages remain relatively stagnant (as they have for many months), those on the bottom rungs of the economic ladder pay the highest price — no pun intended.
Yet, this seems lost on the Biden administration, which seems oblivious to the fact that its reckless spending bills (and COVID-19 policies) are the primary reasons for the spike in inflation.
Since Biden took office, his administration has passed the American Rescue Plan ($1.9 trillion), has supported the bipartisan “infrastructure” plan ($1.2 trillion and pending in the House), and is on the brink of passing a behemoth budget reconciliation package that would cost a whopping $3.5 trillion.
This amount of reckless spending over such a short period is absolutely unprecedented in U.S. history. And lest we forget, this comes on top of the $2.6 trillion the government allocated in COVID-19 relief funds.
As any economist, or anyone with common sense, knows, when the government showers the economy with trillions of dollars over a short window of time, the value of the dollar declines.
And when this colossal spending comes after an 18-month economic shutdown, in which the production of goods and availability of services declined due to government decree, you now have more dollars chasing fewer goods and services.
No wonder inflation is out of control.
Over the past few months, the Biden administration and the Democratic-controlled Congress (with the help of some Republicans) have embraced modern monetary theory, which basically says that debt and deficits don’t matter. According to MMT, the government can spend and print as much money as it deems necessary, without any repercussions.
However, we are witnessing the abject failure of MMT in real-time. Hopefully, some semblance of fiscal sanity will prevail sooner rather than later.

What Biden threw away
"The events we're seeing now," President Biden said Monday afternoon, amid what he called the "gut-wrenching" horror of Kabul's fall, "are, sadly, proof that no amount of military force would ever deliver a stable, united, secure Afghanistan."
Five weeks ago, he said the opposite.
In July, Biden described the Afghan military as "better trained, better equipped, and more competent in terms of conducting war." He scorned the idea that the Taliban could seize the country, and denied that his military and intelligence advisers were warning that a precipitous US withdrawal would be disastrous. "The likelihood there's going to be the Taliban overrunning everything and owning the whole country is highly unlikely."
Not for the first time, Joe Biden was wrong on a key foreign policy and national security issue.
Yet despite abruptly reversing his message on the threat posed by the Taliban, he was as inflexible as ever on getting US troops out of Afghanistan. "We will end America's longest war after 20 long years of bloodshed," Biden repeated, as he had ever since launching his presidential bid two years ago. That had been Donald Trump's position, too; at one point, Trump even signed an order ordering US forces out by Jan. 15, 2021. Until it was removed a few days ago, a page on the Republican National Committee website was still praising Trump for cutting a deal with the Taliban "to end America's longest war."
It is strange, this talking point about Afghanistan being the "longest war" or a "forever war." Yes, the United States has been involved in Afghanistan for almost 20 years, but the last time American forces suffered any combat casualties was Feb. 8, 2020, when Sgt. Javier Gutierrez and Sgt. Antonio Rodriguez were ambushed and killed. Their sacrifice was heroic and selfless. But it makes little sense to speak of a "forever war" in which there are no fatalities for a year and a half.
Nor does it make sense to apply that label to a mission involving just 2,500 troops, which was the tiny size to which the US footprint in Afghanistan had shrunk by the time Biden took office. There are more American military personnel than that assigned to the East African nation of Djibouti (3,000), to the Rota Naval Station in Spain (3,000), to the Persian Gulf monarchy of Bahrain (5,000), and to Kuwait (13,000).
In terms of battlefield risk to Americans, Afghanistan has not been a hot war zone for years. Compared to the peak US presence a decade ago, when 110,000 troops were deployed, 98 percent of America's personnel in Afghanistan have long since come home. "An endless American presence in the middle of another country's civil conflict was not acceptable," Biden insisted, but the US military presence in Afghanistan was nowhere near as "endless" as some other deployments. American soldiers entered Germany in 1944 and 35,000 American soldiers are there today. In April, just before the White House confirmed Biden's plan to remove all troops from Afghanistan by Sept. 11, Defense Secretary Lloyd Austin announced that the huge US military presence in Germany would be expanding by another 500. Should we call that a forever war, too?
What about Korea? More than 70 years after the United States arrived in Korea to defend the South, nearly 30,000 US troops remain there on high alert, a military tripwire in one of the world's most dangerous environments. But not even Biden would walk away from the defense of South Korea's people. Why does he care so much less about Afghanistan's people?
The United States currently deploys nearly 30,000 active-duty military personnel in Korea, a military tripwire in one of the world's most dangerous environments. US forces have been in Korea since 1950 — half a century longer than they have been in Afghanistan.
Hoover Institution scholar Timothy Kane, an economist and former Air Force intelligence officer, decries the "lazy assumption that Afghanistan is eternally undeveloped" and that US boots on the ground have not accomplished great good. "Unlike most conquering armies," he said in an interview, "American troops provide security and investment in the local populace."
Literacy among Afghans has doubled since the Americans arrived in 2001. Infant mortality rates fell by half. Access to electricity, once denied to more than 3 in 4 Afghans, is now nearly universal. When US forces entered Afghanistan, there were just 900,000 children attending school, and all of them were boys. Earlier this year, that number had reached more than 9.5 million, and 39 percent of them were girls.
All this was being sustained in recent years, and the Taliban was being held at bay, with just a relative handful of US troops to provide intelligence, logistics, and air support. "Once American credibility had been established," observed Kane, "the marginal cost of staying the course was minimal." The cost of throwing it away will be far, far higher.

******************************************The New Normal in the Permanent Emergency
Just when the authorities allow us to take off our masks, they demand that we put them back on. Americans might reasonably wonder if there will ever be a return to “normal.” But obey we must, lest we be in gross violation of the mandates created for us by our betters, who know, better than we do, what’s best for us.
From the onset of the lockdowns, one of their loudest critics has been Fox News host Laura Ingraham. Miss Laura has repeatedly expressed her disdain for the term "the new normal.” Even so, the regular old “old normal” had its problems, one of which was how we handled “congregant settings.” We weren’t very prudent about how we mingled, massed, rubbed shoulders, and got together, i.e. congregated.
Efforts to practice “social distancing” in packed congregant settings are sorely tested in many of the activities that we Americans take for granted, such as attending sports events, movies, concerts, bars, restaurants, demonstrations, insurrections, riots, and so on. People like to cram themselves into arenas and work themselves up into an ecstatic quasi-religious frenzy when their tribe’s team carries a ball across a goal line. And all the while they’re breathing on each other and spraying spittle. Young people, especially, have a need to be with each other, and in cramped quarters, as when they queue up to get into exclusive nightclubs, like Studio 54 back in the old days. How many cases of the coronavirus have been passed to the immuno-compromised by young people who’ve attended all-night raves or today’s equivalent of Studio 54?
One of the features of the old normal that we need to leave behind is how we dealt with congregant settings. This kid thinks that attending certain gatherings, like rock concerts, is a version of Hell. But there’s one type of congregant setting that I do go in for, but it involves a more sophisticated group of congregants than rock fans, and that’s opera.
During a 1975 performance of Tristan und Isolde in Dallas, several audience members were having major coughing fits. Finally, in Act 3, their Tristan, the late great Canadian tenor Jon Vickers, had had enough, and from the stage yelled this at the audience: “Shut up with your damned coughing!
Compared to the devastating virus dreamt up for 12 Monkeys, the Wuhan virus is more like the coronavirus that causes the common cold, it’s even rather benign compared to the Spanish flu of a century ago. Despite that, the Democrats are using the pandemic for their own ends. The mandates and lockdowns are the means by which the Dems hope to lock in their political power permanently.
The lockdowns only make sense when protecting the immuno-compromised and the elderly; in other words, those who should already have been locked down, sheltering in place. Rather than a quarantine of just those folks, the authorities quarantined everybody, and in doing so killed off countless small businesses and livelihoods.
If the vulnerable had isolated and hunkered down to wait for a cure, the rest of America could have stayed open for business with just a few safety measures, which was exactly what essential workers did. The lockdowns are one of the more unnecessary and harmful things government has ever inflicted upon the People.
The Democrats have made COVID-19 into “the worst thing ever” to justify their shotgun approach to lockdown. Paradoxically, the more arbitrary and unreasonable the strictures of their lockdowns, the more they seem to lock in their authority.
The Democrats’ New Normal is an authoritarianism that they want to last forever. And the Dems don’t seem to worry about resistance from the People. After all, you aren’t gonna violate the “Permanent Emergency Code,” are you, Mr. Cole?

******************************************Tennessee Governor Bill Lee Makes Masks Optional in Schools
On Monday, Tennessee Gov. Bill Lee (R) signed an executive order allowing parents to opt their children out of any Wuhan coronavirus mask mandates imposed by school districts in the state.
“No one cares more about the health and well-being of a child than a parent,” Lee wrote in his Twitter announcement of the order. “I am signing an EO today that allows parents to opt their children out of a school mask mandate if either a school board or health board enacts one over a district.”
Lee’s order states that parents of K-12 students in any Tennessee public school have the right, via a written notice, to exempt their child from wearing a mask at school, on a school bus, or at any school-related functions.
With the beginning of the school year looming, Tennessee Republicans had encouraged Lee to call a special session of the state legislature to settle the mask issue. House Speaker Cameron Sexton praised Lee’s order in a series of tweets on Monday evening.
“Gov. Lee’s executive order issued today is good news in affirming a parent’s right to make healthcare decisions for their children,” Sexton wrote. "I feel confident the immediate need for a special session has been averted in the interim by using executive orders. However, the House still stands ready to act if the call comes.”
Unlike the executive orders signed by other GOP governors, such as Texas’ Greg Abbott and Florida’s Ron DeSantis, Lee’s order does not explicitly prohibit school districts from enacting mask mandates. In fact, two of Tennessee’s largest school districts, Shelby County Schools and Metro Nashville Public Schools, have left their mask mandates in place.
Lee’s order comes as the mask debate is heating up at school board meetings in Williamson County, Tenn. Last week, a group of parents attending the Williamson County Schools meeting confronted pro-mask mandate board members and doctors as they tried to leave. And on Tuesday evening, a pro-mandate father invoked the Bible as he railed against “careless” anti-maskers in a now-viral speech.
