Top FDA and WHO scientists oppose COVID boosters

On Monday, top scientists around the world-including experts from the FDA and the World Health Organization-opposed the need for widespread coronavirus vaccination.

in a Comment posted on In the top medical journal “The Lancet”, scientists believe that the general population does not need to be boosted because the vaccine is still very effective in preventing serious illness and death. They also mentioned the urgent need to vaccinate unvaccinated people around the world to save lives and prevent more dangerous mutations.

The review is controversial in the U.S. approaching the Biden administration Suggested start date For enhanced promotion, it is recommended that an individual be injected with Pfizer or Moderna COVID-19 vaccine eight months after the second time.The report also announced a large-scale push at the White House Compulsory vaccination In nearly two-thirds of the U.S. workforce, because a small percentage of unvaccinated people continue to Promote high numbers Number of hospitalizations and deaths nationwide.

The FDA’s external panel of experts is holding a highly anticipated meeting this Friday Discuss the application of Pfizer in enhancing dosage.

The 18 co-authors of the Lancet review include Marion Gruber, director of the FDA Office of Vaccines, and Philip Krause, her deputy at the agency. Announced that they would resign in the fallAccording to reports, part of the reason is that they oppose the Biden administration’s boost plan.The commentary was also co-authored by several experts from the World Health Organization, which called on the global Intensified shooting timeout In order to maximize the global vaccination rate-especially in developing countries, the vaccination rate Keep very low.

“The Lancet” paper review Current evidence Protection provided by existing vaccines. Although these vaccines are less protective against Delta variant infections than the predominant Alpha, they still provide very good protection against serious diseases. Although the ability to prevent infections and even symptomatic diseases may decline over time, so far, the protection against serious diseases still seems to be strong.

Three CDC reports released last week confirmed these findings for most age groups, with a greater decline in the population 75 years old or above. One of the studies reviewed recent 570,000 U.S. COVID-19 cases From April to July, compared with vaccinated people, unvaccinated people are nearly 5 times more likely to be infected and more than 10 times more likely to be hospitalized or die.

The author of the Lancet paper wrote: “Therefore, the current evidence does not seem to indicate the need for intensified treatment in the general population, where the efficacy of serious diseases is still high.”

Data from IsraelBooster injections have already begun, and after the third injection of Pfizer vaccine (initially divided into two doses), they showed increased protection against infections and serious diseases. However, the author of The Lancet pointed out that these data were only collected within one week after the booster dose, and it is not clear how long this protective effect will last.

The authors of The Lancet believe that if immunity diminishes over time, boosters may eventually be needed, but more research is needed to determine when. They believe that there is a more urgent need to vaccinate the existing dose in the unvaccinated population. They also suggested that booster doses designed specifically for the main transmission variants of the coronavirus may be stronger and longer lasting.

“Even if you can finally get some benefits from booster vaccination, it will not outweigh the benefits of providing initial protection for people who have not been vaccinated,” the author wrote. “If vaccines are deployed where they can work best, they can accelerate the end of the pandemic by inhibiting the further evolution of mutations.”

Mike Ryan, the head of WHO’s health emergency plan, severely condemned the launch of the booster last month. “We plan to distribute additional life jackets to people who already have life jackets, and we let others drown without a life jacket,” Ryan says. “this is the truth.”
