Leading scientists around the world – including experts from the FDA and the World Health Organization – on Monday fired back shots to revive the coronavirus vaccine.
In one opinion published in In the main medical journal The Lancet, scientists argued that booster shots are not needed in the general population because vaccines are still very effective in preventing serious illness and death. They also mentioned the urgency of giving doses to unvaccinated people around the world in order to save lives and prevent more dangerous variants from appearing.
The review comes as the U.S. Biden administration approaches the debate proposed start date to expand the booster, it is recommended that an individual take a second shot of Pfizer or Moderna COVID-19 vaccines and eight months later. The report also comes a week after the White House announced a major boost ordered the vaccine Nearly two-thirds of U.S. workers continue to have pockets of unvaccinated people driving large numbers hospitalizations and deaths nationwide.
The FDA’s panel of outside experts is holding a highly anticipated meeting this Friday To discuss Pfizer’s booster dose request.
Among the 18 authors of the Lancet review are Marion Gruber, director of the FDA’s immunization office, and Philip Krause, his deputy for the agency, both of whom. they announced their resignation in the fall, in part because of its opposition to the Biden administration’s promotion plan. The review has also been conducted by several experts from the World Health Organization, and has been requested worldwide booster shot moratorium to maximize vaccines worldwide, especially in developing countries, where vaccination rates it remains very low.
The Lancet reviews the paper current evidence about the protection offered by existing vaccines. Although all vaccines offer less protection against infection with the Delta variant, they offer very good protection against serious diseases compared to the predominant Alpha. And while the ability to prevent infections or symptomatic illnesses decreases over time, protection against serious illnesses is strong so far.
Three CDC reports released last week confirmed these findings in most age groups, dropping more sharply in the public. 75 or more. Almost one of the revised studies 570,000 U.S. COVID-19 cases from April to July, people who were not vaccinated were almost 5 times more likely to become infected and 10 times more likely to be hospitalized or die than those who were vaccinated.
“Current evidence, therefore, does not seem to show the need to promote it in the general population, as it remains highly effective against serious diseases,” the authors of the Lancet paper wrote.
Israeli data, which had already begun to spread booster shots, showed increased protection against infections and serious illnesses after a third shot of the Pfizer vaccine, which was initially given in two doses. But the authors of the Lancet noted that the data were only administered for one week after the booster dose was administered, and it is unclear how long this protection will last.
The authors of the Lancet argued that, in the end, enhancers may be necessary if immunity is lowered over time, but more research was needed to determine when this will be necessary. For now, they argued that there is a greater need to administer doses among those without vaccines. They also suggested that booster doses designed specifically against major circulatory variants of coronavirus may be stronger and more persistent.
“Even if a profit can ultimately be made from the boost, it will not outweigh the benefits of providing initial protection to those without vaccines,” the authors wrote. “If vaccines are spread where they would benefit the most, they could accelerate the end of the pandemic by further preventing the evolution of variants.”
Mike Ryan, head of the WHO’s Emergency Health Program, strongly condemned booster shots last month. “We plan to distribute additional life jackets to people who already have life jackets, and while we are letting other people drown without a single life jacket.” said Ryan. “That’s the reality.”
