Who is the study for?
Children aged 2 to <18 years at high risk of RSV disease can join this trial. They may have conditions like cystic fibrosis, asthma, lung issues, Down syndrome, neuromuscular diseases, cerebral palsy or congenital heart disease. For Phase 1 only: kids 2 to <5 must show prior RSV exposure. Parents/guardians must consent and help with study procedures.Check my eligibility
What is being tested?
The trial is testing a vaccine called RSVpreF for safety and immune response in two phases. Phase 1 determines the dose for later stages; all get one shot of the vaccine. In Phases 2/3, participants are randomly given either the vaccine or a placebo without knowing which they received.See study design
What are the potential side effects?
Specific side effects aren't listed but generally could include reactions at the injection site, fever, fatigue or allergic responses. Blood tests will monitor health changes post-vaccination.
