Health Experts Urge Patience on Wider Use of Covid-19 Booster Shots

WASHINGTON—Top U.S. health officials urged patience on broader approval for booster shots for the coronavirus vaccine, two days after a Food and Drug Administration advisory panel recommended that a booster from Pfizer Inc. and BioNTech SE should be limited to the elderly and other groups at higher risk.

“Ultimately, the real, proper regimen will turn out to be the original two shots plus a boost,” said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said on NBC’s “Meet the Press” Sunday. He said officials’ highest priority is to vaccinate unvaccinated Americans.
