Pfizer RSV vaccine lags GSK's as head-to-head competition underway
Pfizer, which dominated COVID vaccine sales, now finds itself looking up at GSK, whose rival new respiratory syncytial virus (RSV) vaccine has surged to an early lead since the shots launched this summer. The British drugmaker's early advantage may be tied to its positioning as the lone RSV shot offered by CVS Health, the biggest pharmacy chain in the U.S. and a dominant player in the retail vaccine market, analysts and industry experts say. Price may also be playing a role, according to independent pharmacists.
