Why CDC is telling certain adults to get the RSV vaccine before fall

The CDC is telling certain older adults to think ahead and get an RSV vaccine before fall. The main groups are adults ages 75 and older, plus adults ages 50 to 74 who are at increased risk of severe RSV illness.

The vaccine can be given any time of year, but the CDC says late summer or early fall is the best window because it offers the most benefit before RSV season typically picks up.

What changed

The current CDC guidance recommends a single RSV vaccine dose for eligible adults. It is not an annual shot, and people who already received one dose do not need another one at this time.

The CDC says there is no preferred brand for adults 50 and older. The agency notes three licensed options are available for this age group.

Who is included

According to the CDC, adults ages 75 and older should get the vaccine. Adults ages 50 to 74 may also qualify if they are at increased risk for severe RSV illness.

That higher-risk group includes people with chronic heart or lung disease, diabetes with complications, severe obesity, kidney failure or dialysis, certain neurologic or neuromuscular conditions, chronic liver disease, serious immune compromise, or residence in a nursing home. The CDC also says clinicians may consider other chronic conditions or frailty when judging risk.

Why timing matters

RSV vaccination is allowed any time, but the CDC says the best time is late summer or early fall, usually August through October in most of the continental United States. The goal is to build protection before RSV season starts to rise in the community.

What the vaccine can and cannot do

The point of the shot is to reduce the chance of severe RSV illness, emergency department visits, and hospitalization. It is not a guarantee against infection, and CDC says protection can wane over time.

CDC’s adult RSV page also notes that RSV usually causes mild cold-like symptoms in adults, but it can sometimes lead to pneumonia, hospitalization, or worsening of asthma, COPD, or heart failure.

Safety and getting other vaccines at the same visit

CDC says RSV vaccines can be given during the same visit as other adult vaccines. The agency also notes that side effects such as soreness at the shot site, fever, headache, and muscle aches may be somewhat more common when vaccines are coadministered.

People with questions about a personal medical condition, prior vaccine reaction, or whether to space out shots should talk with a clinician or pharmacist.

Coverage and next steps

For many adults, the practical next step is simple: check whether the vaccine is available at a doctor’s office, clinic, or pharmacy, and ask whether your insurance plan covers it. KFF has noted that vaccine coverage rules can vary by plan and policy details, so readers should confirm benefits rather than assume they are the same everywhere.

People who are older, frail, or have chronic medical conditions may want to bring this up at their next routine visit, especially if they are planning other fall vaccines.

When to seek care

If someone has RSV symptoms and develops trouble breathing, chest pain or pressure, sudden dizziness or confusion, or difficulty eating or drinking, CDC says to seek medical help promptly. Those can be warning signs of more serious illness.
