U.S. health officials want to make COVID-19 vaccinations more like the annual flu shot. The Food and Drug Administration on Monday proposed a simplified approach so that most adults and children would get a once-a-year shot. Americans would no longer have to keep track of how many shots they’ve received or when. The proposal comes as boosters have become a hard sell. The FDA is asking a panel of outside vaccine experts to weigh in on the new approach at a meeting Thursday. The agency will present data suggesting most Americans have enough protection to move to a once-a-year shots.

Pfizer announced Saturday that tweaking its COVID-19 vaccine to better target the omicron variant is safe and works — just days before regulators debate whether to offer Americans updated booster shots this fall.
