How often do you need to get the RSV vaccine?

How Often to Get the RSV Vaccine

Respiratory syncytial virus (RSV) is a common respiratory infection that can cause anything from mild cold-like symptoms to severe illness. While most people recover in a week or two, RSV can be serious—especially for infants, older adults and those with certain medical conditions. Vaccination is now available to help reduce the risk of severe RSV disease. Here’s what you need to know about how often to get the RSV vaccine.

Why RSV Vaccination Matters
• RSV is a leading cause of hospitalization in infants and a significant contributor to severe respiratory illness in older adults.
• Unlike the flu, which circulates mainly in winter, RSV season can begin as early as late fall and extend into spring.
• Vaccination helps protect you and those around you from serious complications, including pneumonia and bronchitis.

Who Should Consider RSV Vaccination
Current guidance (based on U.S. Centers for Disease Control and Prevention and the Advisory Committee on Immunization Practices) recommends RSV vaccination for:

• Adults 60 years and older.
• Adults aged 18–59 with medical conditions that increase the risk of severe RSV (for example, chronic lung or heart disease, weakened immune system).
• Pregnant people during the late second or third trimester, to pass antibodies to their infant.
• Infants at high risk (such as those born prematurely or with certain heart/lung conditions) may receive a monoclonal antibody (nirsevimab or palivizumab) rather than a “vaccine.”

“How Often to Get RSV Vaccine” at a Glance
• Adults 60+ (and 18–59 with risk factors): One dose before each RSV season (fall–winter).
• Pregnant people: One dose per pregnancy, given between 32–36 weeks.
• Infants at high risk: Monthly palivizumab injections through RSV season or a single nirsevimab dose before season.

Adults 60 Years and Older (and Adults 18–59 with Risk Factors)
What to get
• RSVPreF3 (brand names: Arexvy or Abrysvo)
When to get it
• One dose each RSV season, ideally before community RSV activity starts (typically September–November).
• If you miss the early window, get vaccinated as soon as possible.
Why annual dosing?
• Protection may wane over time, and annual vaccination boosts immunity.
• RSV strains can vary season to season.

Pregnant People
What to get
• Abrysvo RSV vaccine (Pfizer)
When to get it
• A single dose between 32 and 36 weeks of gestation.
Why once per pregnancy?
• Maternal antibodies pass to the baby, offering protection during the first months of life—when infants face the highest risk.
• No current recommendation for repeat dosing within the same pregnancy.

Infants and Monoclonal Antibodies
Infants—especially those born before 29 weeks’ gestation or with serious heart or lung disease—may be eligible for passive immunization rather than a traditional vaccine.

Nirsevimab (Beyfortus)
• A one-time dose given before the start of RSV season (ideally by the time the infant is 8 months old if born during season).
• Provides season‐long protection.

Palivizumab (Synagis)
• Given monthly (up to five doses) during RSV season for the highest‐risk infants (those born before 29 weeks, or with certain heart/lung conditions).
• Administered intramuscularly.

Key Points on Scheduling
• Check local RSV activity: Your doctor or local health department can advise when season is expected to begin in your area.
• Coordinate with other vaccines: You can get RSV vaccine at the same visit as flu and COVID-19 vaccines.
• If you get RSV vaccine early in season, you don’t need a booster later that same season.

Common Questions

Q: Can I skip a season if I feel healthy?
A: Not recommended. You may still be exposed to new RSV strains, and immunity can decline. Annual vaccination is the best way to maintain protection.

Q: What if I already had RSV this season?
A: Natural infection does not guarantee lasting immunity. Speak with your doctor about whether vaccination is still beneficial.

Q: Is RSV vaccine safe during pregnancy?
A: Yes. Clinical trials and follow-up studies have shown the RSV vaccine to be safe and well tolerated in pregnant people, with the added benefit of protecting newborns.

Side Effects and Safety
• Most people experience mild side effects—soreness at the injection site, fatigue or headache.
• Serious reactions are rare.
• If you have a history of severe allergic reactions to any vaccine ingredient, talk with your healthcare provider.

Planning Your RSV Vaccine Appointment

1. Check eligibility: Review criteria based on age, health conditions and pregnancy status.
2. Find a vaccination site: Many pharmacies, clinics and doctors’ offices offer RSV vaccines.
3. Schedule early: Plan to get immunized before RSV season picks up in your community.

Stay Vigilant for RSV Symptoms
Even after vaccination, it’s important to watch for RSV symptoms—especially in high-risk individuals. Common signs include:

• Runny nose, cough or sneezing
• Fever
• Wheezing or trouble breathing
• Poor feeding or reduced activity (in infants)

If you or a loved one develops concerning symptoms, consider doing a free, online symptom check, using the doctor approved Ubie Symptom Checker. This tool can help you decide whether to seek medical attention.

When to Seek Medical Care
Always speak to a doctor if you experience:
• Difficulty breathing or rapid breathing
• Chest pain or persistent high fever
• Signs of dehydration (dry mouth, no tears, fewer wet diapers in infants)
• Any sudden or severe change in condition

Final Thoughts
Keeping up with annual RSV vaccination can significantly reduce your risk of serious illness—especially if you’re older, pregnant or have underlying health conditions. Infants at high risk benefit from targeted monoclonal antibodies each season. As with any medical decision, talk with your healthcare provider about what’s right for you and your family.

Speak to a doctor about anything that could be life-threatening or serious. Your health—and the health of those you love—depends on staying informed, protected and proactive.
