Phase 3 mRNA Investigational RSV Vaccine Trial

Now Enrolling

While there is currently no approved vaccination to prevent respiratory syncytial virus (RSV) illnesses, scientists are researching an investigational mRNA vaccine in this study.

RSV can cause infections of the lungs and respiratory tract, and can lead to serious conditions such as pneumonia and bronchiolitis, especially for seniors and immunocompromised people. RSV hospitalizes an estimated 177,000 seniors (age >65) in the U.S. each year.

Eligible participants…

  • Must be age 50 or older
  • Will receive an investigational mRNA RSV vaccine or placebo at no cost
  • Will also receive an investigational mRNA COVID-19 booster vaccine at no cost
  • Must be fully vaccinated for COVID-19, with the last shot in the primary series having been administered at least 150 days ago, or more than 120 days ago if it was a booster
  • Could receive up to $900 compensation for study-related time
