The Food and Drug Administration said vaccines cleared in the U.S. currently provide sufficient protection against severe disease and death from Covid-19 without additional doses, potentially complicating the Biden administration’s deliberations over the need for booster shots.
The FDA released the findings Wednesday in a report analyzing data submitted by Pfizer Inc. and BioNTech SE as part of their request for authorization for their vaccine to be given as a booster shot in people 16 years and older.
An outside panel of scientific advisers will review the FDA report on Friday, along with a companion analysis from Pfizer and other information, as part of a discussion over who needs booster shots and when.
The Biden administration had targeted next week to start widely distributing the extra shots to counter contagious variants such as Delta and bolster signs of waning immunity among the vaccinated.
Evidence supporting the need for an extra dose, at least in the general public, hasn’t been conclusive.
