FDA will allow fully vaccinated Americans to get COVID-19 booster shots that are different than the vaccine they initially received

The FDA will allow Americans to receive a COVID-19 booster shot that is different than the vaccine they received
Officials are expected to approve extra doses for the Moderna and Johnson & Johnson shot this week
It comes after the NIH presented data last week showing that J&J recipients had higher antibody levels after a Pfizer or Moderna booster
The J&J booster raised antibody levels four-fold over two weeks while Pfizer’s booster raised levels 45-fold and the Moderna booster spiked levels 76-fold
Moderna’s booster was also found to raise antibody levels higher among Pfizer recipients than Pfizer’s third dose
