GSK stays a step ahead in RSV vaccine battle as Arexvy becomes available at US pharmacies

As companies have flocked to compete in the new respiratory syncytial virus (RSV) vaccine market, GSK has had the best timing.

In May, the U.K. company was first to secure FDA approval for its shot Arexvy for adults 60 and older, beating out rivals from Pfizer and Moderna. And now—well in advance of the fall and winter RSV season—Arexvy is available in major U.S. retail pharmacies, GSK said Thursday.
