If you’re wondering whether the rsv vaccine for adults is for you, the answer depends on your age, health, and where you live. U.S. CDC guidance recommends one dose for everyone aged 75 and older, and for adults aged 50–74 at increased risk of severe RSV illness. It is not currently an annual vaccine.
RSV Vaccine for Adults: WHO Qualifies in the U.S.?
The U.S. recommendation is age- and risk-based:
- Age 75 or older: one dose is recommended, regardless of whether you have a listed risk condition.
- Age 50–74: one dose is recommended if you have a condition or other risk factor that increases your chance of severe RSV illness. This includes adults aged 50–59 under the expanded U.S. recommendation adopted in 2025.
The risk-based recommendation does not mean every person in their 50s, 60s or early 70s qualifies. Ask a healthcare professional to check your health history against the current CDC criteria; the specific qualifying conditions matter.
There is also a difference between a vaccine being authorised for use and being recommended for routine use. The U.S. FDA has authorised two RSV vaccines for some adults aged 18–49 who are at increased risk of RSV illness, but the CDC recommendation described here begins at age 50. If you are under 50 and have significant health risks, ask your clinician whether current guidance applies to you.
Is It One Dose, Or Do You Need A Booster?
For adults who qualify under current U.S. guidance, the recommendation is a single dose. You do not need another dose every RSV season, and people who have already received an RSV vaccine are not currently recommended to get another one.
That does not mean protection is known to last for life. CDC reports some decline in protection over time in clinical-trial data for the available vaccines. The length of follow-up differs by product, and ongoing monitoring will help guide future advice. For now, waning protection has not led to a recommended booster or repeat schedule. If you were vaccinated previously, do not assume you need a new dose each year; check current national guidance before arranging one.
When Should You Get Vaccinated?
In the continental United States, eligible adults can be vaccinated at any time of year, but CDC says late summer or early fall—usually August through October—is likely to offer the most benefit before RSV season. If you live elsewhere, do not automatically use those months: ask a local healthcare professional when vaccination fits your region’s RSV season and programme.
What If You Live In The UK, EU Or Australia?
The age thresholds above describe U.S. CDC guidance; they do not establish who is eligible, when vaccination is offered or whether it is publicly funded in another country. In the UK, an EU country or Australia, check the current advice from your national or local immunisation programme. Access and eligibility rules can be programme-specific, so a U.S. recommendation is not a substitute for local guidance.
The vaccines discussed in U.S. guidance include Arexvy, Abrysvo and mResvia. CDC does not prefer one product over another for eligible adults; the vaccine available to you may depend on local authorisation and programme arrangements.
What To Ask Before Booking
If you are aged 50–74, ask whether your health conditions meet the risk criteria where you live. If you have already had an RSV vaccine, ask whether your local guidance recommends any further dose before booking another. And if you are 75 or older, confirm where vaccination is available and when it is best timed for your region.
These recommendations are designed to help prevent serious RSV illness, not to guarantee that you will avoid infection or hospital care. A clinician or pharmacist can help you apply the guidance to your age, health and vaccination history.
