how often rsv vaccine for adults
Adults currently only need one RSV vaccine dose in their lifetime; it is not an annual shot like the flu vaccine.
How often do adults need the RSV vaccine?
- Current guidance (2025–2026):
- Adults who are recommended to get it should receive a single dose only.
* If you already got an RSV vaccine in a previous season, you **should not** get another dose at this time.
- There is no schedule for repeat doses yet (no “every year” or “every 5 years” recommendation).
- Experts and public health agencies are still collecting data to decide whether booster doses might be needed in the future.
Who is it recommended for?
- Everyone 75 and older : one dose.
- Adults 50–74 (or 60–74 in some guidance) who have higher risk for severe RSV, such as:
- Chronic heart or lung disease
- Weakened immune system
- Certain other serious medical conditions
The exact age cutoffs can vary slightly by organization, but all agree that only one dose is needed for now.
When is the best time to get it?
- You can technically get it any time of year, but the ideal timing is late summer to early fall , before RSV season ramps up in winter.
Why isn’t it yearly like the flu shot?
- RSV vaccines for adults are relatively new , and studies are still ongoing on how long protection lasts.
- Current evidence suggests protection is lasting enough that repeat doses are not recommended yet.
- Agencies like CDC and advisory groups will update recommendations if future data show that boosters improve protection.
Quick table: adult RSV vaccine frequency
| Group | Recommendation | How often |
|---|---|---|
| Adults 75+ | Get 1 dose of an RSV vaccine if not yet vaccinated. | [5][7][1]One‑time only (no repeat doses currently). | [7][1]
| Adults 50–74 at higher risk | Get 1 dose after discussing risk with a clinician. | [9][5][1][7]One‑time only for now. | [1][7]
| Adults who already got RSV vaccine | No additional dose recommended currently. | [9][7][1]Do not repeat each season. | [7][1]
What should you do personally?
- If you’re in a higher‑risk group (especially 75+ or 50–74 with heart, lung, or other serious conditions), it is worth asking your doctor or pharmacist if you should get your one-time RSV shot.
- If you already had an adult RSV vaccine, you’re considered up to date and do not need another dose right now.
- Because recommendations can change as new data comes in, it’s wise to check with a clinician each fall about the latest guidance in your area.
Bottom line: For adults, the RSV vaccine is currently a one‑and‑done shot , not an annual vaccine, with future booster recommendations still under study.
