Study of immune responses during and after flu infection
This study looks at how your immune system (your body’s infection-fighting system) responds during and around the time of a flu illness. It’s meant to help researchers better understand immune changes in healthy adults and may guide future flu care.
Atlanta, GeorgiaAges 18–64 - NCT06067555RecruitingEarly Phase 1
Flu vaccine study for healthy adults

Common questions
- Are there clinical trials studying Influenza vaccine?
- Yes. Clin2 currently lists 57 recruiting studies that include Influenza vaccine, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Influenza vaccine trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Influenza vaccine an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Influenza vaccine or a specific trial is right for you.
