[1/3] View of Pfizer's new respiratory syncytial virus (RSV) vaccine Abrysvo during its manufacture in this undated handout picture. "800 POUND GORILLAS"CVS, which has more than 9,000 U.S. locations, declined to comment on why it was only carrying GSK's vaccine. It was not immediately clear how many RSV shots were being administered in pharmacies versus doctors' offices. GSK declined to discuss its RSV vaccine contracts, but said customer relationships gives it a competitive advantage. Two independent pharmacists said they are being charged a lower price by wholesalers for the GSK vaccine, which comes in boxes of 10.
