A Food and Drug Administration official said the best time for an additional shot may be fall, when the spread of the coronavirus is expected to pick up again
WASHINGTON — Although new federal data suggests that the effectiveness of booster shots wanes after about four months, the Biden administration is not planning to recommend fourth doses of the coronavirus vaccine anytime soon.
“We simply don’t have enough data to know that it’s a good thing to do,” Dr. Peter Marks, who heads the division of the Food and Drug Administration that regulates vaccines, said in an interview this week.
In a separate interview, Dr. Anthony S. Fauci, the chief medical adviser to the White House, said the vaccines are still a firm bulwark against severe illness, despite data from the Centers for Disease Control and Prevention showing that booster shots lose some of their potency after four to five months.
