US FDA approves expanded use of Moderna's RSV vaccine for at-risk adults
- On June 12, 2025, the FDA expanded approval of Moderna's RSV vaccine mRESVIA to include adults aged 18 to 59 at increased risk in the United States.
- This expansion follows earlier FDA approval in 2024 for adults 60 and older and an April CDC advisory panel recommendation for at-risk adults aged 50 to 59, though the CDC director has not yet endorsed it.
- MRESVIA protects against serious RSV infections affecting the lungs and airways, demonstrating an effectiveness between 79 and 83.7 percent in late-stage clinical trials, with more than one-third of adults aged 18 to 59 having health conditions that raise their risk of severe RSV illness.
- Moderna CEO Stéphane Bancel highlighted that RSV represents a significant threat to adults with specific chronic illnesses, and he described the vaccine’s authorization as a key advancement in protecting more people from severe RSV disease. The vaccine is anticipated to be available for the 2025-2026 respiratory season.
- Despite FDA approval, the CDC's vaccine panel was recently fired and replaced by appointees of Health Secretary Kennedy, leaving official recommendations and insurance coverage for the new age group uncertain.
