Vaccinated Americans would “not necessarily” need to get booster shots this fall for further protection from COVID-19, Dr. Anthony Fauci said Friday.

Fauci, the nation’s leading infectious disease expert, told CBS “This Morning” that scientists would be tracking data on the virus and variants that may emerge with some resistance to the current vaccines.

It was still “possible,” he said, that an additional shot would be needed later this year to ward off possible infection.


With so many Americans becoming immunized, it’s natural to look ahead and wonder how long this protection will last. The answer: No one knows.

Fauci also urged Americans to continue to follow CDC guidelines. He stressed those who haven’t been fully vaccinated still need to wear masks even if they are largely spending time with people who have been inoculated.

He added that those attending indoor sporting events, such as the NBA playoffs starting this week, should follow the masking policies of the arena.
