NEW YORK — U.S. health officials are recommending all Americans get COVID-19 booster shots.
The plan, as outlined by the director of the Centers for Disease Control and Prevention and other top health authorities, calls for booster doses eight months after people get their second shot of the Pfizer or Moderna vaccine.
The booster doses could begin the week of Sept. 20.
Health officials say people who received the single-dose Johnson & Johnson vaccine also probably need extra shots because some effectiveness of vaccines wanes over time. But they say they’re awaiting more data and have yet to work out the details.
The overall plan awaits a Food and Drug Administration evaluation of the safety and effectiveness of a third dose, the officials say.
