CDC urges older adults to plan RSV shots before late summer

Adults who are eligible for RSV vaccination do not need to wait for the first hint of fall. CDC says the best time to get the shot is in late summer or early fall, before RSV usually starts to spread in the community.

That matters because RSV can be more serious for older adults and some people with chronic health conditions. The vaccine is meant to lower the chance of severe illness and hospitalization, not guarantee that someone will never get infected.

What changed

CDC now recommends a single RSV vaccine dose for all adults ages 75 and older, and for adults ages 50 to 74 who are at increased risk of severe RSV illness. People who have already received one dose are considered finished for now and should not get another RSV dose at this time.

Why timing matters

CDC says eligible adults can be vaccinated at any time of year, but the shot is expected to offer the most benefit if given in late summer or early fall, just before RSV season usually begins in the continental United States. In most of the continental U.S., that window is August through October.

CDC’s latest respiratory-illness data say the amount of acute respiratory illness causing people to seek care is very low as of May 8, 2026. RSV activity started later than expected in many regions this season, and higher activity may continue into May in some areas.

Who qualifies

In plain language, CDC recommends RSV vaccination for:

Adults age 75 and older.
Adults ages 50 to 74 who have a higher risk of severe RSV illness.

CDC lists several conditions that can raise risk, including chronic heart disease, chronic lung disease, diabetes with complications, kidney failure or dialysis, neurologic or neuromuscular conditions that affect breathing or airway clearance, chronic liver disease, severe obesity, moderate or severe immune compromise, and nursing home residence. If someone is unsure whether they qualify, CDC recommends checking with a clinician or pharmacist.

What the vaccine does and does not do

The RSV vaccine is designed to reduce the chance of serious disease, emergency care, and hospitalization. It is not a guarantee against infection, and it is not currently an annual vaccine.

CDC says RSV vaccines can be given at the same visit as other adult vaccines. It also notes that common side effects such as pain at the injection site, fever, headache, or muscle aches may be more frequent when vaccines are given together.

What current data show

CDC’s weekly RSV vaccination dashboard shows that many eligible older adults still have not been vaccinated. Among adults 75 and older, reported coverage varied widely by jurisdiction, and Medicare fee-for-service coverage among eligible enrollees was 36.9% as of January 31, 2026.

CDC’s wastewater monitoring can detect respiratory viruses earlier than clinical testing and before people seek care, which can help communities watch for spread. It is useful context, but it does not replace individual vaccination decisions or medical evaluation.

What families and caregivers can do now

For many households, the practical next step is simple: check whether an older adult in the family is eligible, ask a clinician or pharmacist about the RSV shot, and ask whether it can be given at the same visit as other recommended vaccines.

Caregivers should also watch for warning signs such as trouble breathing, chest pain, confusion, dehydration, or symptoms that are getting worse rather than better. Those symptoms should prompt urgent medical advice, and severe breathing trouble should be treated as an emergency.

The bottom line

CDC’s message is not that RSV is an immediate alarm for everyone. It is that eligible older adults should plan ahead now, before the next RSV season builds, so they can be vaccinated during the window when the shot is expected to provide the most benefit.
