According to the epidemiologist, the need for repeated vaccination will depend on the behavior of the South African strain.

Leading US infectious disease expert Dr. Anthony Fauci conceded that Americans will still have to wear masks in 2022. Still, measures to combat the spread of COVID-19 will weaken as more people are vaccinated.

Fauci said this in an interview with CNN.

“I think we will reach a significant level of ‘normality’ after the terrible burden we had to bear last year,” Fauci said.

Fauci said.

Speaking on NBC, Fauci said it’s too early to say when collective immunity will be introduced in the United States.

When asked by Fox News whether Americans would need a secondary vaccination, he said it would depend on how the South African strain of the coronavirus develops.
