Faced with a surge in coronavirus cases driven by the fast-spreading omicron variant, U.S. health officials said people should get a booster shot with the Pfizer Inc.-BioNTech SE vaccine five months after their first two shots.
The new recommendation, which shortens the interval from the previous six-month regimen, comes a day after the U.S. Food and Drug Administration changed its emergency authorization for the shot to reflect a shorter dosing interval for the booster.
