Pfizer asks FDA for full booster dose approval
Pfizer on Wednesday asked the Food and Drug Administration for full approval for a booster dose. The company said its Phase 3 data showed that people who received a third dose between five to eight months after the second shot had antibody levels three times higher than levels seen after the second dose.
Because the Pfizer shots were approved by the FDA on Monday, Pfizer is now asking the agency to consider a "supplemental" application for boosters for people ages 16 and over. This is a "rolling submission," with Pfizer intending to complete the submission by the end of the week.
The Biden administration said its goal is to have boosters available beginning Sept. 20, with the recommendation of getting one eight months after the second shot of Pfizer or Moderna.
