WATCH: No clarity yet on how many COVID vaccine boosters will be needed in the future, Fauci says

Future booster shots of the COVID-19 vaccine will probably be necessary, but how often a person will need to get the jab to be protected is not yet known, National Institute of Allergy and Infectious Diseases Director Dr. Anthony Fauci said on Wednesday.

The hearing is expected to begin at 10 a.m. ET. Watch the event in the player above.

“It is very likely that all of us who’ve been vaccinated will have a diminution of the level of protection after a certain number of months, and it is likely that there will be recommended for everyone to get a boost then,” Fauci told the House Appropriations Committee on Wednesday.

Fauci said it wasn’t yet known whether boosters were necessary due to the introduction of new and different variants. But so far, in the “omicron era,” vaccines have worked, he said. A determination of whether more boosters were necessary and how often would come later.

“I think sometime in the middle of the summer, we’re going to know what the cadence is going to be about, how often we’re going to vaccinate.”

Fauci said that while immunity given by vaccines will wane, they have continued to protect recipients from serious illness. People over the age of 50 are already eligible for a fourth dose
