WASHINGTON: Additional additional Vaccine Booster Covid-19 is not needed for the general population, leading scientists including two senior food officials and US drugs departing and some of the World Health Organizations (WHO) said in an article published in medical journals on the day Monday .
Scientists say more evidence is needed to justify the booster.
It sees disagree with the US government’s plan to start offering another round of shots to many Americans who are fully vaccinated immediately after next week, depending on the approval of the health regulator.
As a Covid-19 case caused by the Delta variant of the increase in viruses, President Joe Biden’s government relating to infection among those who had been vaccinated was a sign that their protection was reduced and had pushed booster as a way to rebuild immunity.
Who argues that vaccines are still needed for the first dose throughout the world.
“Every decision about the need to increase or determine the time to be based on careful analysis of clinical data or epidemiology that is adequately controlled, or both, shows a reduction that is persistent and meaningful in severe illness,” wrote scientists in the medical journal Lancet.
The risk-benefit evaluation must consider the number of severe Covid-19 cases that are enhanced will be expected to prevent, and whether safe and effective against the current variants, they said.
“Therefore, current evidence seems to show the need to increase the general population, where the efficacy of severe disease remains high,” the scientists wrote.
Some countries have started a Covid-19 booster campaign, including Israel, providing some data where Biden’s administration has made the case for additional shots.
The author of the article included the FDA Office of the Research and review of the Marion Gruber vaccine and Deputy Director of Phil Krause, both of them planned to leave the body in the next few months.
They recognize that some individuals, like those who are immunocompromised, can benefit from additional doses.
The wider use of booster may be needed in the future if there is immunity with primary vaccination or if the new variant evolves so that the vaccine no longer protects against viruses, they said.
Booster can also prove risky if introduced too fast or too often, scientists write.
The expert panel that suggested FDA on vaccines planned to meet on September 17 to discuss additional doses of Pfizer / Bionth Shot, the first step in the launch of a wider booster.
Article writers include who Soumya Swaminathan’s top scientist, Ana-Maria Henao-Restrepo and Mike Ryan.
“The current vaccine equipment can save more life if used in the population previously not vaccinated,” writers.
