It’s too early to tell whether those now getting COVID-19 booster shots will one day need a second or third booster, National Institute of Allergy and Infectious Diseases Director Anthony Fauci said during a White House COVID-19 Response Team press briefing.

“We do not know at this point, but we are collecting data that hopefully will inform us about that,” Fauci said when asked by a reporter if people will need to get a fourth vaccination shot six months after their booster or if boosters will eventually be given every six months in order to maintain a defense against the virus.
