Pfizer (PFE) Says Covid-19 Vaccine Efficacy Erodes Over Time - Bloomberg
FDA Staff Report
According to a meeting agenda the FDA posted on its website, the Friday panel meeting will include presentations from the Centers for Disease Control and Prevention, FDA staff, researchers from Israel and the U.K., along with Pfizer.
Marion Gruber, one of two top vaccine officials who FDA recently said will step down later this year, is also scheduled to speak. Gruber was co-author of an article in The Lancet earlier this week arguing that booster shots weren’t yet necessary for most people. The departure of the two longtime agency staffers is a potential sign of friction over the Biden booster plan.
Officials from Israel will present data from that country on booster protection against infections and severe disease, according to the agenda, and a professor of medical statistics from the University of Bristol will present data on real-world vaccine effectiveness.
The staff’s 23-page briefing paper noted that the likely benefit of a booster shot would depend on how much the third shot reduces disease relative to the first two. If the first two shots are still highly effective, then the efficacy of the booster shot “is likely to be more limited,” the staff said. Overall data in the U.S. indicate that the first two shots of the vaccine still protect against severe disease and death, the staff said.
The staff also noted that it is not currently clear whether there will be an increased risk of inflammation of the heart and heart lining after a booster shot, and that potential risks of a booster shot also must be considered. It didn’t offer a clear indication of which way the agency was leaning, which it often does before meetings.

Out of control vaccine stockpiling by rich nations can lead to disaster for the world. – Scientific Inquirer
The allocation of COVID-19 vaccine between countries has thus far tended toward vaccine nationalism, wherein countries stockpile vaccines to prioritize access for their citizenry over equitable vaccine sharing. The extent of vaccine nationalism, however, may strongly impact global trajectories of COVID-19 case numbers and increase the potential emergence of novel variants, according to a Princeton University and McGill University study published Aug. 17 in the journal Science.
“Certain countries such as Peru and South Africa that have had severe COVID-19 outbreaks have received few vaccines, while many doses have gone to countries experiencing comparatively milder pandemic impacts, either in terms of mortality or economic dislocation,” said co-first author Caroline Wagner, an assistant professor of bioengineering at McGill University who previously served as a postdoctoral research associate in Princeton’s High Meadows Environmental Institute (HMEI).
“As expected, we have seen large decreases in case numbers in many regions with high vaccine access, yet infections are resurging in areas with low availability,” said co-first author Chadi Saad-Roy, a Princeton graduate student in ecology and evolutionary biology and the Lewis-Sigler Institute for Integrative Genomics.
“Our goal was to explore the effects of different vaccine-sharing schemes on the global persistence of COVID-19 infections — as well as the possibility for the evolution of novel variants — using mathematical models,” Saad-Roy said.
The researchers projected forward the incidence of COVID-19 cases under a range of vaccine dosing regimes, vaccination rates, and assumptions related to immune responses. They did so in two model regions: One with high access to vaccines — a high-access region (HAR) — and a low-access region (LAR). The models also allowed for the regions to be coupled either through case importation, or the evolution of a novel variant in one of the regions.
“In this way, we could assess the dependence of our epidemiological projections on different immunological parameters, regional characteristics such as population size and local transmission rate, and our assumptions related to vaccine allocation,” Wagner said.
Overall, the study found that increased vaccine-sharing resulted in reduced case numbers in LARs. “Because it appears that vaccines are highly effective at reducing the clinical severity of infections, the public health implications of these reductions are very significant,” said co-author Michael Mina, an assistant professor at the Harvard T. H. Chan School of Public Health.
Senior author C. Jessica E. Metcalf, a Princeton associate professor of ecology and evolutionary biology and public affairs and associated faculty in HMEI, added: “High case numbers in unvaccinated populations will likely be associated with higher numbers of hospitalizations and larger clinical burdens compared to highly vaccinated populations.”
The authors also drew on a framework developed in their prior work to begin trying to quantify the potential for viral evolution under different vaccine sharing schemes. In their model, repeat infections in individuals with partial immunity — either from an earlier infection or a vaccine — may result in the evolution of novel variants.
“Overall, the models predict that sustained elevated case numbers in LARs with limited vaccine availability will result in a high potential for viral evolution,” said senior author Bryan Grenfell, Princeton’s Kathryn Briger and Sarah Fenton Professor of Ecology and Evolutionary Biology and Public Affairs and an associated faculty member in HMEI.
“As with our earlier work, the current study strongly underlines how important rapid, equitable global vaccine distribution is,” Grenfell said. “In a plausible scenario where secondary infections in individuals who have previously been infected strongly contribute to viral evolution, unequal vaccine allocation appears particularly problematic.”
As the pandemic progresses, viral evolution may play an increasingly large role in sustaining transmission, said senior author Simon Levin, Princeton’s James S. McDonnell Distinguished University Professor in Ecology and Evolutionary Biology and an associated faculty member in HMEI. “In particular, antigenically novel variants have the potential to threaten immunization efforts globally through several mechanisms,” he said,” including higher transmissibility, reduced vaccine efficacy, or immune escape.”
Saad-Roy added: “In this way, global vaccine coverage will reduce the clinical burden from novel variants, while also decreasing the likelihood that these variants emerge.”
There are additional considerations for vaccine equity beyond epidemiological and evolutionary ones, said co-author Ezekiel Emanuel, the Diane v.S. Levy and Robert M. Levy University Professor and co-director of the Healthcare Transformation Institute at the University of Pennsylvania.
“Ethics also argues against countries stockpiling vaccines or allocating doses for boosters,” Emanuel said. “This study strongly supports that ethical position showing that stockpiling will undermine global health.”

Physicians handing out Covid 19 vaccination exemptions for school
California Medical Association (CMA) President Peter N. Bretan, Jr., M.D., issued the following statement in response to rogue physicians selling bogus mask exemptions:
"We are deeply troubled by reports that a few rogue physicians have decided to ignore the science surrounding the spread of COVID-19 and place the lives of children and their families in danger. There are very few medical reasons and situations that would exempt an individual from masking requirements. It strains credulity to think that a single physician would have dozens or hundreds of patients with valid medical claims for such an exemption. Unfortunately, we know there are bad actors who are willing to operate outside the accepted standards of care in order to turn a personal profit. This needs to stop. Physicians have an obligation and a duty to uphold the oath we all take when we assume the awesome responsibility of practicing medicine. Stories like the one coming out of Roseville undermine the credibility of the medical profession and put members of the public at risk. We need strong, immediate action to ensure bad actors are not given carte blanche to interpret the law as they wish."
So, the official word from the CMA exposes this unethical as well as a potentially dangerous practice. In addition, any physician who does this risks his medical license and can be sanctioned or face termination of his medical license. Physicians are placed in a dual role, one of having a good relationship with their patients, especially primary care physicians who see their patients frequently. They must also use good judgment to not allow a patient to harm themself. The term for this is primum non nocere, a consideration used by all physicians to judge whether to prescribe a particular treatment. In determining this the physician uses the risk/benefit of a particular treatment or non-treatment. In the risk of non-vaccination, it far outweighs the risk for treatment. The risks vary according to age, and chronic conditions. Certain other immunologic conditions in children increase the risk of vaccination.
