F.D.A. to Allow ‘Mix and Match’ Approach for COVID Booster Shots

The agency may act this week on the matter

The Food and Drug Administration is planning to allow Americans to receive a different Covid-19 vaccine as a booster than the one they initially received, a move that could reduce the appeal of the Johnson & Johnson vaccine and provide flexibility to doctors and other vaccinators.

The government would not recommend one shot over another, and it might note that using the same vaccine as a booster when possible is preferable, people familiar with the agency’s planning said. But vaccine providers could use their discretion to offer a different brand, a freedom that state health officials have been requesting for weeks.

The approach was foreshadowed on Friday, when researchers presented the findings of a federally funded "mix and match" study to an expert committee that advises the Food and Drug Administration. The study found that recipients of Johnson & Johnson's single-dose shot who received a Moderna booster saw their antibody levels rise 76-fold in 15 days, compared with only a fourfold increase after an extra dose of Johnson & Johnson.
