COVID-19: Pfizer booster shot to start by September 20 in US, hints Anthony Fauci

"We hope that Moderna would also be able to do it, so we could do it simultaneously," the country's top infectious disease expert Anthony Fauci said.

Washington: The US` booster shot campaign against Covid-19 will likely start with only the Pfizer vaccine from September 20, the country`s top infectious disease expert Anthony Fauci has said. The rollout for Moderna`s booster vaccine could, however, be delayed, CNBC news quoted Anthony Fauci as saying on Sunday. Although both drugmakers have applied to the US Food and Drug Administration (FDA) for authorisation of a third dose either six months or eight months after getting the second dose, they haven`t been officially approved by the agency.
