When did the RSV vaccine come out?

When did the RSV vaccine come out? Respiratory syncytial virus (RSV) is a common respiratory infection that can be serious in infants, older adults and people with weakened immune systems. After decades of research, the first RSV vaccines were approved in 2023, marking a major milestone in preventing severe RSV illness.

A brief history of RSV prevention

• Since the 1990s, doctors have used monoclonal antibodies (for example, palivizumab) to help protect high-risk infants and young children from RSV.
• Those products are not vaccines: they provide passive immunity and require monthly injections during RSV season.
• For decades, an active vaccine that trains the immune system to fight RSV on its own remained elusive.

When did RSV vaccine come out? Key approval dates

The first RSV vaccines for adults received U.S. Food and Drug Administration (FDA) approval in May 2023:

• May 3, 2023
  • Arexvy (GSK) approved for adults aged 60 and older
  • Abrysvo (Pfizer) approved for adults aged 60 and older
• August 2023
  • Abrysvo received an expanded recommendation for use in pregnant people between 32 and 36 weeks’ gestation, to help protect newborns in their first months of life
• July 2023
  • Beyfortus (nirsevimab-anbm) approved for infants and toddlers up to 24 months at high risk of severe RSV; this single-dose monoclonal antibody injection provides passive protection through the RSV season

Why 2023 mattered

• For the first time, people can get an RSV vaccine that activates their own immune response.
• Older adults, who face a higher risk of hospitalization and serious complications from RSV, finally have tailored protection.
• Pregnant people can help shield their babies via antibodies passed before birth.
• Infants with certain risk factors can receive Beyfortus to reduce hospital admissions.

How the adult RSV vaccines work

Both Arexvy and Abrysvo are made from a stabilized portion of the RSV “fusion” (F) protein. By presenting this harmless piece of the virus, they prepare the body to recognize and fight RSV if exposed.

• Single dose, given before RSV season (typically fall/winter in the U.S.)
• Can be co-administered with flu and COVID-19 vaccines, per CDC guidance
• Clinical trials showed a 67–86% reduction in severe RSV illness in adults 60+ over the first RSV season

Who should get the RSV vaccine?

Current U.S. recommendations (subject to change—always check the latest CDC guidance):

• Adults aged 60 years and older
• Pregnant people between 32 and 36 weeks’ gestation (using Abrysvo)
• Infants and toddlers up to 24 months with certain medical conditions (using Beyfortus)

Talk with your healthcare provider about timing and any personal health factors.

Benefits and considerations

Pros:

• Major drop in hospitalizations and severe RSV infection
• One-time season-based dose for most adults
• Protection for newborns when given during pregnancy

Considerations:

• Mild side effects: injection-site pain, fatigue, muscle aches
• Cost and insurance coverage vary
• Not a substitute for good hygiene: handwashing and avoiding sick contacts remain important

What to watch for after vaccination

Most people tolerate RSV vaccines well. If you experience any of these serious symptoms, seek medical care right away:

• High fever lasting more than 48 hours
• Severe shortness of breath or chest pain
• Signs of allergic reaction: hives, swelling of face or throat, difficulty breathing

For any concerning symptoms, please speak to a doctor. You might also try a free, online symptom check, using the doctor approved Ubie Symptom Checker to help triage your next steps.

Looking ahead

• Ongoing studies are evaluating booster doses and long-term protection.
• Research is underway for universal RSV vaccines that cover multiple virus strains.
• Expanded access programs aim to reach underserved communities.

Key takeaways

• “When did RSV vaccine come out?” Answer: May 3, 2023, for the first adult RSV vaccines.
• These approvals represent decades of research finally translating into real-world prevention.
• Speak with your healthcare provider about RSV vaccination if you are 60 or older, pregnant, or caring for a high-risk infant.
• For any serious or life-threatening concerns, always consult a doctor rather than relying solely on online information.
