RSV vaccine for older adults: who should get it and when
CDC’s updated adult RSV guidance says many older adults should get one RSV vaccine dose before fall respiratory season. For people 75 and older, and for adults 50 to 74 at higher risk, the key questions are when to plan vaccination and what to expect afterward.
CDC updated its adult RSV guidance on February 24, 2026. For many older adults, the main question is whether to get vaccinated before respiratory virus season picks up.
The answer depends on age and health history. CDC recommends a single RSV vaccine dose for all adults 75 and older and for adults 50 to 74 who are at increased risk for severe RSV illness.
Who should get it
CDC says adults 75 and older should receive one dose. Adults 50 to 74 should also get the vaccine if they have conditions that raise the risk of severe disease, such as chronic heart or lung disease, severe obesity, kidney disease, some neurologic conditions, diabetes with complications, immune compromise, or residence in a nursing home.
For people in those age groups, the goal is to lower the chance of severe RSV illness and hospitalization.
When to get vaccinated
Eligible adults can get the RSV vaccine at any time of year. But CDC says the best time is late summer or early fall, usually August through October in most of the continental United States, before RSV begins spreading more widely.
That timing can help families and caregivers plan ahead, especially if the older adult also wants other vaccines during the same season.
What to expect
For now, CDC recommends only one RSV dose. It is not an annual vaccine at this time, and people who already received a dose should not get another one right now.
CDC also says there is no preferred brand for adults 50 and older. The licensed options include Arexvy, mResvia, and Abrysvo. RSV vaccines can be given at the same visit as other adult vaccines, although getting several shots together may increase common short-term reactions such as sore arm, fever, headache, or muscle aches.
Side effects and cautions
The most common reactions are usually short-lived and include injection-site pain, fatigue, headache, and muscle aches. A recent post-licensure study in older adults found that most reported symptoms were temporary and did not require medical care.
That kind of study cannot prove every symptom was caused by the vaccine, but it does help show what people commonly report after vaccination in real-world use.
Seek urgent medical care if symptoms seem severe, if breathing becomes difficult, or if a person has signs of an allergic reaction such as swelling of the face or throat, widespread hives, or trouble breathing.
Why it matters for older adults
RSV often starts like a bad cold, but in older adults it can lead to pneumonia, hospitalization, or worsening of existing heart or lung disease. CDC notes that older adults and people with chronic conditions, frailty, or nursing home residence are more likely to become seriously ill.
That is one reason prevention matters even when RSV seems like a seasonal virus people may associate mostly with young children.
What readers and caregivers can do
If you are 75 or older, or if you are 50 to 74 and have a condition that increases risk, check whether you already qualify for RSV vaccination. If you do, late summer is a good time to ask your clinician or pharmacy about scheduling before the fall season.
If you care for an older adult, help review their vaccine list, ask whether RSV vaccination fits with their flu and COVID-19 plans, and watch for breathing problems or worsening chronic symptoms if they do become sick.
The bottom line: for many older adults, RSV vaccination is a seasonal prevention step worth planning now, not later.
