Respiratory Syncytial Virus Infections study: PIV5-vectored RSV Vaccine

Official title A Study of BLB-201 RSV Vaccine in Infants and Children

ClinicalTrials.gov ID: NCT05655182

What this study is testing

What is PIV5-vectored RSV Vaccine (BLB-201) Low Dose?

This is an investigational nasal spray being studied to help prevent respiratory syncytial virus (RSV) infections in young children. It is designed to use a harmless parainfluenza virus to carry instructions into cells so the body can learn to recognize and fight RSV.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study checks if the vaccine is safe, well tolerated, and can trigger an immune response in infants and children.
Who it's for
Infants 8‑24 months old and children 18‑59 months old, whether or not they have had RSV before.
What's involved
Participants receive one of two vaccine doses or a placebo through the nose, then have follow‑up visits and blood tests to monitor safety and immune response.
Time commitment
The study lasts about 6 months, with several clinic visits for vaccination, monitoring, and blood sampling.
  • Phase 2: a mid-size study of how well it works
  • You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance.
