Part of Infections, Lungs & breathing clinical trials.

This study gives you a flu vaccine and measures how your immune system reacts, including both “blood immunity” and “cell immunity.” It’s for healthy adults and mainly aims to better understand how well flu vaccines work in people without major health issues.
