FDA Pushes for Moderna Booster Shot Data in Weighing Dose

U.S. health regulators are seeking additional coronavirus booster shot data from Moderna Inc., as the Biden administration expects to begin a widespread booster campaign this month with only the Pfizer Inc.-BioNTech vaccine, people familiar with the matter say. Moderna announced Friday that it had “completed” its submission of data to the Food and Drug Administration for authorization of boosters. The FDA has been seeking more data as Moderna’s submission rolled in, the people added.
