Could a simple vaccine slash COPD attacks?
NCT ID NCT07508644
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a single dose of the RSV vaccine (Arexvy) can reduce moderate-to-severe COPD flare-ups in people who have frequent attacks. Researchers will enroll 320 high-risk patients aged 50+ and follow them for one year. Half will get the vaccine plus standard care, the other half standard care alone.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
RSV vaccine (Arexvy)
What this could lead to
If it works, this could reduce the number of serious COPD flare-ups by at least 20%, offering a new way to manage the disease.
What could go wrong
This is a Phase 4 trial, but it's open-label (no placebo), which can bias results. The 20% reduction target is modest, and the vaccine may not work for everyone.
