The Food and Drug Administration authorized Moderna and Pfizer’s Covid booster shots for all U.S. adults on Friday, belatedly fulfilling a critical part of the Biden administration’s plan to administer extra doses to the general public as growing data demonstrates the efficacy of vaccines wanes over time.
The approval comes about two months late — after scientists advising the FDA rejected the administration’s original plans to start distributing boosters to all adults the week of Sept. 20, citing a lack of data supporting the third doses.
FDA Acting Commissioner Janet Woodcock also cleared the doses without the usual public meeting to review new data submitted by the companies in the last week. Moderna resubmitted its application just two days ago. The companies announced the decision Friday morning.
