NCT ID NCT02511002
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 200 people who have had the flu to see how their immune system changes over two years. Participants give blood and nasal samples every three months. The goal is to learn how long antibodies last and how they change, which could help create more effective flu vaccines.
