Americans who received the Pfizer-BioNTech or Moderna coronavirus vaccines should get a booster shot eight months after their second vaccine dose, federal health officials said on Wednesday.
The boosters will be available beginning Sept. 20, if the Food and Drug Administration agrees to the plan. They will go first to health care workers, nursing home residents and older adults, who were the first to receive the initial round of vaccinations after they were authorized in December.
But the recommendation does not apply to the nearly 14 million Americans who received the single-shot Johnson & Johnson vaccine.
“For people who received the Johnson & Johnson vaccine, we anticipate vaccine boosters will likely be needed,” Dr. Vivek Murthy, the surgeon general, said at a White House news briefing on Wednesday.
He added: “We expect more data on J.&J. in the coming weeks. With those data in hand, we will keep the public informed of a timely plan for J.&J. booster shots.”
In the meantime, here are answers to some common questions.
