Pfizer Asks FDA to Authorize Second Covid-19 Booster Dose

Pfizer Inc. and partner BioNTech SE have asked U.S. health regulators to authorize a second booster dose of their Covid-19 vaccine for people 65 years and older. The companies said Tuesday that they had filed the application. The Food and Drug Administration is expected to make a decision in time for the Biden administration to begin a potential fall vaccine campaign. The FDA has been reviewing data and looking at potentially authorizing a fourth dose of the shot for use in the fall, The Wall Street Journal reported last month. Health authorities have cleared booster doses for children as young as 12 years of age, at least five months after they finished their first round of vaccination.
