Pfizer's Abrysvo Gains FDA Approval for Younger Adults, Challenging GSK's Market Hold

The FDA has expanded approval of Pfizer's Abrysvo vaccine to include adults aged 18 to 59 who are at increased risk of respiratory syncytial virus (RSV). This expansion positions Abrysvo as the first RSV vaccine in the U.S. available for this younger demographic, who are susceptible to RSV-related lower respiratory tract disease due to chronic conditions such as obesity or diabetes[1][2]. The decision is supported by successful results from the Phase 3 MONeT trial, which demonstrated strong immune responses in at-risk individuals, including the immunocompromised[3][4]. This approval may strengthen Pfizer's position in the RSV vaccine market against competitors such as GSK's Arexvy.
