WASHINGTON — The U.S. approved the first vaccine for RSV on Wednesday, shots to protect older adults against a respiratory virus that’s most notorious for attacking babies but endangers their grandparents, too.

The Food and Drug Administration decision makes GSK’s shot, called Arexvy, the first of several potential vaccines in the pipeline for RSV to be licensed anywhere.
