NCT ID NCT04919109
First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time
Summary
This early-stage trial tests an experimental RSV vaccine called CodaVax-RSV, given as nose drops, in healthy children aged 6 months to 5 years. The study evaluates the vaccine's safety and the immune response it triggers. Some children receive the vaccine at different doses, while others get a placebo (saline nose drops). Participants are monitored closely for side effects and antibody levels.
