WASHINGTON (AP) — U.S. regulators have approved updated COVID-19 vaccines from Pfizer and Moderna, shots aimed at revving up protection this fall and winter.

The Food and Drug Administration’s decision Monday is part of a shift to treat fall COVID-19 vaccine updates much like getting a yearly flu shot.

The Centers for Disease Control and Prevention must sign off.

Its advisers meet Tuesday to recommend how to best use this round of vaccinations.

The shots could begin later this week.

Both the COVID-19 and flu shot can be given at the same time.
