Coverage, Supply Issues Dampen Promise of New RSV Immunizations

After years of having just one, limited option available to combat respiratory syncytial virus (RSV) in at-risk populations, the U.S. market this year has suddenly become rich with new products. Yet insurance coverage limitations and supply issues are frustrating efforts to keep elderly adults and very young babies from contracting what can be a life-threatening illness. 

This May, the FDA approved both GSK’s Arexvy and Pfizer Inc.’s Abrysvo for people who are 60 and older, and in August, federal regulators approved Abrysvo for use in people who have been pregnant for 32 to 36 weeks, with the goal of protecting their infants after birth. Additionally, in July, the FDA approved Sanofi/AstraZeneca’s Beyfortus (nirsevimab-alip), a monocolonal antibody injection indicated for preventing RSV in newborns and infants born during or entering their first RSV season, and for children up to 24 months old who remain vulnerable to severe disease throughout their second RSV season.
