- As for all the talk about booster doses, the FDA's licensure doesn't cover those. The agency will decide that separately.
The FDA already is allowing emergency use of a third dose of either the Pfizer or Moderna vaccine for people with severely weakened immune systems, such as organ transplant recipients who don't respond as strongly to the usual two shots. For everyone else who got those vaccinations, the Biden administration is planning ahead for boosters starting in the fall — if the FDA and CDC agree.
Also still to be decided is vaccination of children under 12. Both Pfizer and Moderna are studying youngsters, with data expected in the fall. -
