As U.S. prepares to launch boosterScientists question the necessity of the third COVID-19 injection and whether it needs to be an annual event.
This week, the Centers for Disease Control and Prevention issued a joint letter approving the third dose of Americans vaccinated with Pfizer or Moderna. However, CDC Director Dr. Rochelle Walensky said on Thursday that this COVID-19 booster injection may not recur every year, because the third injection may be enough to strengthen the individual’s long-term protection.
Valensky said on the CBS “This Morning” show: “This virus has always been ashamed, so I don’t want to say never, but we don’t necessarily expect you to need this virus every year.” “Look. It is true that after the third dose, you got a very strong response, so we will continue to follow the science in terms of vaccines and viruses.”
However, some scientists question whether the third dose is necessary.
CNBC says Some scientists severely criticized the Biden administration for promoting the widespread distribution of the Covid-19 vaccine booster starting on September 20, saying that the data provided by federal health officials this week is not enough to recommend a third dose to the majority of the US population now.

The administration also received Sharp criticism from global leaders, They widely called for a moratorium on COVID-19 and intensified injections to resolve Vaccine supplies are in short supply in poor countries.
Despite these criticisms, the US booster program will remain.
