The recombinant respiratory syncytial virus (RSV) vaccine Arexvy (GSK) has now received FDA approval for use in adults 50-59 years old who are at increased risk for lower respiratory tract disease (LRTD) caused by RSV. It was previously approved only for adults ≥60 years old. Two other RSV vaccines have received FDA approval: Abrysvo, a recombinant vaccine that is licensed for use in adults ≥60 years old and in pregnant women at 32-36 weeks' gestation to prevent RSV-associated LRTD in their infants, and mResvia, an mRNA vaccine recently licensed for use in adults ≥60 years old that will be available for the 2024-25 RSV season.

Two recombinant vaccines, Arexvy (GSK) and Abrysvo (Pfizer), have been approved by the FDA for prevention of lower respiratory tract disease (LRTD) caused by respiratory syncytial virus (RSV) in adults ≥60 years old. They are the first RSV vaccines to be approved in the US. Abrysvo is also approved for use in pregnant women at 32-36 weeks' gestation to prevent LRTD caused by RSV in their infants from birth through 6 months of age.
