Pfizer booster shot may start in US by September 20: Anthony Fauci

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 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 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.


Even as the approvals are pending, the Joe Biden administration has announced plans to offer third doses to people who received the Pfizer and Moderna shots.

"Only the Pfizer vaccine booster may get FDA and Centers for Disease Control and Prevention (CDC) approval in time for a rollout the week of September 20," Fauci was quoted as saying on CBS' aceFace the Nation."

"Looks like Pfizer has their data in, likely would meet the deadline," Fauci said.
