(The Wall Street Journal) 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.
Data from vaccine manufacturers and other countries under review by the Food and Drug Administration is based on boosters being given at six months, the person said. The person said approval for boosters for all three Covid-19 shots being administered in the U.S.—those manufactured by Pfizer Inc. and partner BioNTech SE, Moderna Inc. and Johnson & Johnson —is expected in mid-September.
