White House chief medical advisor Dr. Anthony Fauci said Thursday everybody will someday “likely” need a booster shot of the Covid-19 vaccines.

“We’re already starting to see indications of some diminution” in the durability of the vaccines, Fauci told, “CBS This Morning.”

Everybody Will Likely Need a Covid Vaccine Booster Shot Eventually, Says Fauci

The priority, Fauci said, is to give boosters to people who have compromised immune systems, including those with cancer and transplanted organs.

“We don’t feel at this particular point that, apart from the immune-compromised, we don’t feel we need to give boosters right now,” he said.

“Such people, including cancer and HIV patients, represent only about 2.7% of the U.S. adult population but make up about 44% of hospitalized Covid breakthrough cases, which is when a fully vaccinated individual becomes infected”, according to recent data from a Centers for Disease Control and Prevention advisory group.

But Fauci, speaking Thursday on NBC’s “TODAY,” said “inevitably there will be a time when we’ll have to get boosts.”

“No vaccine, at least not within this category, is going to have an indefinite amount of protection,” he said.
