3rd major COVID-19 vaccine shown to be effective and cheaper
Drugmaker AstraZeneca says that late-stage trials show its COVID-19 vaccine is highly effective, buoying the prospects of a relatively cheap, easy-to-store product that may become the vaccine of choice for the developing world
The results are based on an interim analysis of trials in the U.K. and Brazil of a vaccine developed by Oxford University and manufactured by AstraZeneca. No hospitalizations or severe cases of COVID-19 were reported in those receiving the vaccine.
AstraZeneca is the third major drug company to report late-stage data for a potential COVID-19 vaccine as the world waits for scientific breakthroughs that will end a pandemic that has pummeled the world economy and led to 1.4 million deaths. But unlike the others, the Oxford-AstraZeneca vaccine doesn’t have to be stored at freezer temperatures, making it potentially easier to distribute, especially in developing countries..
“I think these are really exciting results,” Dr. Andrew Pollard, chief investigator for the trial, said at a news conference. “Because the vaccine can be stored at fridge temperatures, it can be distributed around the world using the normal immunization distribution system. And so our goal … to make sure that we have a vaccine that was accessible everywhere, I think we’ve actually managed to do that.”
The Oxford-AstraZeneca vaccine was 90% effective in preventing COVID-19 in one of the dosing regimens tested; it was less effective in another. Earlier this month, rival drugmakers Pfizer and Moderna reported preliminary results from late-stage trials showing their vaccines were almost 95% effective.
While the AstraZeneca vaccine can be stored at 2 degrees to 8 degrees Celsius (36 degrees to 46 degrees Fahrenheit), the Pfizer and Moderna products must be stored at freezer temperatures. In Pfizer’s case, it must be kept at the ultra-cold temperature of around minus-70 degrees Celsius (minus-94 Fahrenheit).
The AstraZeneca vaccine is also cheaper.
AstraZeneca, which has pledged it won’t make a profit on the vaccine during the pandemic, has reached agreements with governments and international health organizations that put its cost at about $2.50 a dose. Pfizer’s vaccine costs about $20, while Moderna’s is $15 to $25, based on agreements the companies have struck to supply their vaccines to the U.S. government.
All three vaccines must be approved by regulators before they can be widely distributed.
Oxford researchers and AstraZeneca stressed they weren’t competing with other projects and said multiple vaccines would be needed to reach enough of the world’s population to end the pandemic.
“We need to be able to make a lot of vaccine for the world quickly, and it’s best if we can do it with different technologies so that if one technology runs into a roadblock, then we’ve got alternatives, we’ve got diversity,” professor Sarah Gilbert, a leader of the Oxford team, told The Associated Press. “Diversity is going to be good here, but also in terms of manufacturing, we don’t want to run out of raw materials.”
AstraZeneca said it will immediately apply for early approval of the vaccine where possible, and it will seek an emergency use listing from the World Health Organization, so it can make the vaccine available in low-income countries.
The AstraZeneca trial looked at two different dosing regimens. A half-dose of the vaccine followed by a full dose at least one month later was 90% effective. Another approach, giving patients two full doses one month apart, was 62% effective.
That means that, overall, when both ways of dosing are considered, the vaccine showed an efficacy rate of 70%.
Gilbert said researchers aren’t sure why giving a half-dose followed by a larger dose was more effective, and they plan to investigate further. But the answer is probably related to providing exactly the right amount of vaccine to get the best response, she said.
“It’s the Goldilocks amount that you want, I think, not too little and not too much. Too much could give you a poor quality response as well …,” she said. “I’m glad that we looked at more than one dose because it turns out to be really important.”
The vaccine uses a weakened version of a common cold virus that is combined with genetic material for the characteristic spike protein of the virus that causes COVID-19. After vaccination, the spike protein primes the immune system to attack the virus if it later infects the body.
Peter Openshaw, professor of experimental medicine at Imperial College London, said the finding that a smaller initial dose is more effective than a larger one is good news because it may reduce costs and mean more people can be vaccinated with a given supply of the vaccine.
“The report that an initial half-dose is better than a full dose seems counterintuitive for those of us thinking of vaccines as normal drugs: With drugs, we expect that higher doses have bigger effects, and more side-effects,” he said. “But the immune system does not work like that.”
The results reported Monday come from trials in the U.K. and Brazil that involved 23,000 people. Of those, 11,636 people received the vaccine — while the rest got a placebo.
Overall, there were 131 cases of COVID-19. Details on how many people in the various groups became ill weren’t released Monday, but researchers said they will be published in the next 24 hours.
Late-stage trials of the vaccine are also underway in the U.S., Japan, Russia, South Africa, Kenya and Latin America, with further trials planned for other European and Asian countries.
Researchers said they expect to add the half dose-full dose regimen to the U.S. trial in a “matter of weeks.’’ Before doing so they must discuss the changes with the U.S. Food and Drug Administration.
The AstraZeneca trials were paused earlier this year after a participant in the U.K. study reported a rare neurological illness. While the trials were quickly restarted in most countries after investigators determined the condition wasn’t related to the vaccine, the FDA delayed the U.S. study for more than a month before it was allowed to resume.
AstraZeneca has been ramping up manufacturing capacity, so it can supply hundreds of millions of doses of the vaccine starting in January, Chief Executive Pascal Soriot said earlier this month.
Soriot said Monday that the Oxford vaccine’s simpler supply chain and AstraZeneca’s commitment to provide it on a nonprofit basis during the pandemic mean it will be affordable and available to people around the world.
“This vaccine’s efficacy and safety confirm that it will be highly effective against COVID-19 and will have an immediate impact on this public health emergency,’’ Soriot said.
British Health Secretary Matt Hancock said he felt “a great sense of relief” at the news from AstraZeneca.
Britain has ordered 100 million doses of the vaccine, and the government says several million doses can be produced before the end of the year if it is approved by regulators.
Just months ago, “the idea that by November we would have three vaccines, all of which have got high effectiveness … I would have given my eye teeth for,” Hancock said.
From the beginning of their collaboration with AstraZeneca, Oxford scientists have demanded that the vaccine be made available equitably to everyone in the world so rich countries can’t corner the market as has happened during previous pandemics.
Leaders of the world’s most powerful nations on Sunday agreed to work together to ensure “affordable and equitable access” to COVID-19 drugs, tests and vaccines.
“If we don’t have the vaccine available in many, many countries, and we just protect a small number of them, then we can’t go back to normal because the virus is going to keep coming back and causing problems again,” Gilbert said. “No one is safe until we’re all safe.”

*********************************Biden’s ‘Build Back Better’ Plan Is Central Planning on Steroids
For more than two centuries, the American economy has been predicated upon free-market capitalism, which has led to the United States becoming the most prosperous and innovative nation in the history of the world.
However, the free-market engine that has fueled unprecedented American ingenuity and wealth creation could be in jeopardy. And it might happen sooner than you think.
According to Joe Biden’s economic agenda, known as the Build Back Better plan, “This is the moment to imagine and build a new American economy for our families and the next generation.”
Biden’s new American economy would be made possible via an influx of government spending, central planning, and regulations on the fossil fuel industry, among others.
However, to actually build a new American economy, it would also include dispensing with many of the principles and policies that created the current American economy. This would be unwise.
To accomplish these joint objectives, Biden has laid out an audacious agenda, which he claims “will mobilize the American people in service of four bold, national efforts to address four great national challenges.”
Before diving into his four bold, national efforts, it is disconcerting that Biden believes the national government, which has a long track record of failed economic interventions, would be capable of accomplishing such a monumental (and unnecessary) task.
Among his four bold, national efforts, first and foremost, Biden plans to “build a strong industrial base and small-business-led supply chains to retain and create millions of good-paying union jobs in manufacturing and technology across the country.”
As stated above, this would be best accomplished by the free-market instead of the national government. Time after time, the federal government has attempted to “create millions of good-paying jobs” and almost all of these attempts have failed.
From FDR’s New Deal policies to alleviate the Great Depression to Obama’s massive stimulus to cure the ails of the Great Recession, the national government has been unable to jumpstart the economy. In the midst of the pandemic-induced downturn, this same logic would apply.
Second, Biden plans to “meet the climate crisis, build a clean energy economy, address environmental injustice, and create millions of good-paying union jobs.”
Again, this is outside the purview of the national government. And if history is any guide, the national government’s recent attempts to subsidize green energy projects, such as Solyndra, have been less than stellar. Innovation is best accomplished through tinkering and trial-and-error, not via bureaucrats with gobs of money to waste.
The third pillar of Biden’s Build Back Better plan would provide free childcare, enhanced compensation for teachers, and more resources for those who care for the elderly.
Although this is laudable, it would do little to reignite America’s economy. And the nation cannot afford it, given our national debt exceeds $27 trillion.
The fourth and final part of his plan is perhaps the most insidious. According to his website, Biden would “pursue a dedicated agenda to close the racial wealth gap, to expand affordable housing, to invest in Black, Latino, and Native American entrepreneurs and communities, to advance policing and criminal justice reform, and to make real the promise of educational opportunity regardless of race or zip code.”
As covered previously, the federal government can ill afford to expand upon its already extensive social safety net programs. And like most of his proposals, much of these would be much better accomplished at the local level. And if Biden is concerned with educational opportunity, especially in minority communities, he would advocate for school choice, instead of doubling-down on failed government schools.
Biden’s Build Back Better plan is heavy on the rhetoric, light on specifics, and hopelessly misguided. If implemented in full, it would add more federal government oversight and spending in a time when the opposite approach would be a better path.
Instead of cajoling Americans into pursuing four bold, national agendas, we would all be better off if we were left to our own devices, while pursuing our own life, liberty, and happiness.
