NCT ID NCT06620185
First seen Apr 22, 2026 · Last updated May 23, 2026 · Updated 4 times
Summary
This study looks at how the immune system responds to the flu, either from a nasal spray vaccine or a controlled infection with a lab-made flu virus. Healthy adults aged 18-55 will be split into two groups to compare symptoms and immune reactions. The goal is to better understand how the body fights the flu, not to test a new treatment.
