NCT ID NCT07717840
First seen Jul 21, 2026 · Last updated Jul 22, 2026 · Updated 1 time
Summary
This study tests an experimental vaccine called AZD6489 in adults aged 60 and older. The vaccine is designed to protect against respiratory syncytial virus (RSV), a common virus that can cause serious lung infections in older people. Participants receive a single injection of either the new vaccine or a licensed RSV vaccine, and researchers monitor safety and immune response over time.
