You usually do not need an RSV vaccine every year. One dose is currently recommended for eligible adults, and repeat or yearly doses are not advised at this time.

Quick Scoop: How Often Do You Need the RSV Vaccine?

For winter 2025–2026, guidance in the U.S. is:

  • The RSV vaccine is not an annual shot like the flu vaccine.
  • If you already received an RSV vaccine (even last year), you are not advised to get another dose right now.
  • Protection from the current RSV vaccines appears to last for at least two RSV seasons , and experts are still studying how long it truly lasts and whether boosters will be needed in the future.

“One and done (for now)” is the current vibe: get your dose when you become eligible, then wait for updated guidance rather than planning on a yearly shot.

Who is supposed to get it?

Current U.S. guidance for adults focuses on higher‑risk groups:

  • Adults 75+ : recommended to get a single RSV vaccine dose.
  • Adults 50–74 with higher risk (such as chronic heart or lung disease, weak immune system, or other serious conditions): recommended to get a single dose.
  • Others under 60 or 50 may be considered in special high‑risk situations, depending on their health and doctor’s judgment.

For pregnancy , one RSV vaccine (Abrysvo) can be given during weeks 32–36 of pregnancy in RSV season to help protect the newborn, but this is a one‑time pregnancy‑specific dose, not a yearly series.

When should you time it?

  • Best timing is late summer to early fall (around August–October) so protection is strongest when RSV season ramps up.
  • If you haven’t had the RSV vaccine yet and you’re eligible, you can get it any time of year , but it gives the most benefit before RSV starts circulating widely.

Imagine it like putting snow tires on before winter: one well‑timed dose going into the season, not a new set every month.

Will this change in the future?

  • Experts are actively tracking how long protection lasts and whether boosters or repeat doses will be useful or needed.
  • Guidance may change over the next few years as more real‑world data accumulates, especially with newer vaccines on the market.

Because recommendations are evolving, it’s smart to:

  1. Ask your doctor or pharmacist if you personally should get an RSV vaccine now.
  2. Check once a year (for example each summer or fall) if guidance about repeat dosing has changed.

Bottom line: For adults, RSV vaccination is currently a one‑time dose for those who qualify, not a yearly shot, and you should wait for updated public health guidance before getting any additional doses.
