Fauci, President Biden’s chief medical adviser for Covid-19, said on Sunday that Americans may still be wearing masks outside their homes a year from now, even as he predicted the country would return to “a significant degree of normality” by fall.

Fauci appeared on a series of TV news programs on Sunday morning, where he was quizzed on the dangers of variants of the coronavirus, the schedule of the nation’s vaccine rollout and when vaccination would allow more students to return to schools.

Fauci said on “Fox News Sunday” that he hoped high school students, far fewer of whom have gone back to classrooms compared with younger children, would be eligible for vaccination in the fall.

Fauci said on NBC News’s “Meet the Press” that it was prudent for people to stick to the prescribed schedule.

Fauci said on “Fox News Sunday” that while it is still rare in the United States, “if it becomes more dominant, we may need a version of the vaccine that’s effective specifically against” it
