26 August 2021 - Pfizer, BioNTech have requested clearance for COVID-19 vaccine boosters that an official said could be administered six months after previous dose.
Federal regulators are likely to approve a COVID-19 booster shot for vaccinated adults starting at least six months after the previous dose rather than the eight-month gap they previously announced, a person familiar with the plans said, as the Biden administration steps up preparations for delivering boosters to the public.
