First seen Jan 10, 2026 · Last updated Apr 28, 2026 · Updated 14 times

Summary

This study looks at how the flu vaccine changes immune cells in the nose, which are the body's first line of defense against respiratory germs. Researchers will collect samples from 30 healthy adults who choose to get the flu shot. The goal is to learn more about local immunity, not to test a new treatment.
