How Often Is RSV Vaccine Required, and Who Is Eligible

Respiratory Syncytial Virus (RSV) can cause serious lung and airway infections in babies, older adults and people with certain health conditions. Thanks to recent advances, safe and effective RSV vaccines and antibody products are now available. Understanding how often you need protection and who should get it can help you plan ahead.

How Often Is RSV Vaccine Required?

Current recommendations focus on timing protection around RSV “season” (usually fall through spring), when infections rise. Here’s how often different groups should receive RSV prevention:

• Adults 60 years and older

  • One dose of RSV vaccine each RSV season.
  • Optimal timing: before local RSV activity ramps up (often late summer or early fall).
  • If you miss the usual window, getting vaccinated later is better than not at all.

• Pregnant people (to protect newborns)

  • A single dose during each pregnancy, ideally between 32 and 36 weeks gestation.
  • Even if you’ve had RSV vaccine in a previous pregnancy, you should receive it again for each new pregnancy.

• Infants and young children at high risk

  • A one-time dose of RSV monoclonal antibody (nirsevimab) before the first RSV season.
  • In some high-risk infants (e.g., born extremely premature or with certain heart/lung conditions), a second dose may be considered if their first dose was given very early before the season starts.
  • No routine RSV vaccination for otherwise healthy infants or toddlers; focus is on those at highest risk.

• Adults 50–59 years and 18–49 years with underlying conditions

  • Not currently recommended for routine use in healthy adults under 60, but if you have chronic lung disease, heart disease, severe immunocompromise or other risk factors, talk to your doctor about whether RSV vaccine might be appropriate off-label.

Why a Once-a-Season Dose?

• RSV infections peak seasonally, similar to flu.
• Protection wanes gradually over months, so a yearly dose before the season provides optimal coverage.
• Annual dosing simplifies scheduling—just like the annual influenza shot—so you don’t miss the window of peak RSV activity.

Who Is Eligible for RSV Vaccination?

Eligibility differs by age group and health status. Below is a summary based on the latest U.S. Centers for Disease Control and Prevention (CDC) and Advisory Committee on Immunization Practices (ACIP) guidance.

1. Adults Aged 60 and Older

   • All adults 60+ are recommended to receive one RSV vaccine dose each season.
   • Two different vaccines are available; your healthcare provider can help choose the best option.

2. Pregnant People (During Each Pregnancy)

   • One dose between 32–36 weeks of pregnancy to boost antibodies passed to the baby.
   • Protects infants during their first few months, when they’re most vulnerable.

3. Infants and Young Children at High Risk

   • Nirsevimab monoclonal antibody is approved for infants born at any gestational age.
   • A single dose is given just before RSV season starts.
   • Eligible infants include those born prematurely (<35 weeks gestation), with chronic lung disease, congenital heart disease, neuromuscular disorders, or severe immunocompromise.

4. Adults 18–59 with High-Risk Conditions

   • No universal recommendation, but if you have severe heart or lung disease, immune compromise, or other factors, discuss RSV vaccination with your doctor.
   • They may consider it to reduce severe illness risk.

Why Certain Groups Are Prioritized

• Older adults often have weaker immune responses and more chronic health conditions, increasing the chance of severe RSV illness.
• Infants, especially those born early or with medical issues, lack fully developed lungs and immune systems.
• Pregnant people receive a maternal vaccine not just for themselves but to protect infants too young to be vaccinated.
• Immunocompromised individuals (any age) may not clear the virus well and can develop serious complications.

Benefits of RSV Vaccination

• Reduces the chance of hospitalization and severe lung disease.
• Lowers the need for intensive medical care, such as breathing support.
• Protects against long-term respiratory issues that sometimes follow severe RSV infection.
• Contributes to community immunity, reducing virus spread to vulnerable people.

Practical Tips for Getting Your RSV Vaccine

• Plan ahead: Talk to your healthcare provider in late summer or early fall to schedule your RSV vaccine.
• Combine visits: If you’re also due for flu or COVID-19 vaccines, ask if you can get them at the same appointment.
• Keep records: Note the date and which vaccine you received—especially important for pregnant people who need one dose per pregnancy.
• Stay informed: RSV season timing can vary by region; check local health department updates.

Recognizing RSV Symptoms

Even with vaccination, some people may still get mild RSV. Common symptoms include:

• Runny nose, congestion
• Coughing
• Fever (not always present)
• Decreased appetite
• Wheezing or rapid breathing (more common in infants and older adults)

If you or a loved one develops worrisome symptoms—trouble breathing, bluish lips, high fever, refusal to drink fluids—seek medical care right away.
