The RSV vaccine is currently recommended as a single dose for eligible adults, particularly all adults aged 75 and older and those aged 50–74 who are at increased risk of severe RSV disease. It is not currently an annual vaccine, so once you receive one dose, additional doses are not needed at this time. The optimal time for vaccination is in late summer or early fall before the RSV season begins. Recommendations for revaccination may change as more data become available in the future.
Key Points on RSV Vaccine Frequency:
- One single dose is recommended for eligible adults (75+ and at-risk 50–74).
- Not given annually like flu vaccines.
- Best given before the RSV season (late summer to early fall).
- Future revaccination guidelines may be updated based on ongoing evaluation.
- Coadministration with other vaccines is possible but may increase common side effects.
This guidance applies primarily to adults and may differ for infants or pregnant people who receive RSV preventive products differently.
