New RSV vaccine trial aims to shield seniors from deadly lung infections
NCT ID NCT07272434
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Phase 3 trial is testing a new RSV vaccine in 25,000 adults aged 60 and older. The goal is to see if a single shot can prevent lower respiratory tract disease caused by RSV. Participants are randomly assigned to receive either the vaccine or a placebo, and researchers will monitor safety and immune response over time.
What this could mean

- What this could lead to
- If successful, this vaccine could protect older adults from serious RSV-related lung infections, reducing hospitalizations and deaths.
- What could go wrong
