Study how vaccines work in aging and frailty adults
Part of Infections, Lungs & breathing clinical trials.
This trial studies how well your immune system responds to a vaccine in people who are younger adults or, especially, older adults and those with frailty. Your participation may help researchers understand why vaccine responses can differ with age.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be within either age range: 21–40, or 65 and older
- Be able to understand the study and say yes to participate (or have a legal surrogate if needed)
- Plan to stay in the New Haven, Connecticut area for the next 4–6 weeks
- Do not currently have a short-term illness or fever/symptoms in the past 2 weeks
- Do not be on antibiotics for a current infection in the past 2 weeks (prophylaxis use may be allowed)
- If you’ve had a serious reaction to an influenza shot before, you likely cannot join

This trial tests an influenza (flu) vaccine in people aged 60 and above. It aims to see if the vaccine is safe and works well for older adults, who are at higher risk for flu complications.
This trial tests a flu vaccine (split virus type) for adults aged 60+ to see how well it works and how safe it is. It might help protect older adults from the flu.
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.
This study looks at getting an influenza (flu) vaccine in adults age 75 and older. It may help doctors understand how to safely give flu shots to older adults.
This study looks at how your lungs and lymph nodes respond to flu infection and the nasal flu vaccine. It will help researchers understand how to create better protection against the flu.
This trial tests an experimental mRNA flu vaccine in healthy adults ages 18 to 59. Researchers want to see if it is safe and helps the body build protection against the flu.
