Healthy volunteers inhale RSV virus to help fight future outbreaks
NCT ID NCT02484417
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study gave healthy adults a mild dose of respiratory syncytial virus (RSV) in a controlled hospital setting to learn how the body fights the infection. Thirty-two volunteers aged 18 to 50 stayed in isolation for about 10 days while researchers monitored symptoms, viral shedding, and immune responses. The goal is to use this knowledge to develop better vaccines and treatments for RSV, which can be severe in young children and older adults.
