Long-term follow-up after an influenza challenge study
Part of Infections, Lungs & breathing clinical trials.
This study keeps track of how your body’s immune responses change over time after an influenza exposure. Researchers may use stored blood samples to study specific antibody levels, which could help improve future flu vaccines or treatments.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have already taken part in an influenza challenge study, or a related natural history study through the LID unit
- You’re willing to have your samples stored for future research use
- You agree to provide scheduled blood samples if needed during follow-up
- If you join another influenza challenge study, you may be removed until that challenge is finished
- A study doctor must agree that your health situation makes the blood sample plan safe and won’t affect the study goals

This trial tests how the body reacts to a specific flu virus (pH1N1) in a controlled setting. Healthy volunteers are exposed to the virus to help researchers understand the infection and test treatments. You will be monitored closely and given antiviral medication if needed.
This study looks at how people's immune systems respond to the flu. If you have a positive flu test at a Penn Medicine location and are 18 or older, you may be able to join.
This observational study looks for digital health patterns during studies where people are intentionally exposed to a respiratory virus. If you join a respiratory virus challenge at NIH, you may help researchers discover better ways to monitor and understand illness using wearable devices and shared health data.
This study enrolls healthy adults to help set up future research studies about infectious diseases. If you qualify, you may be asked to join later “healthy volunteer” experiments and allow your samples to be stored for future research.
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.
This is a long-term study that evaluates and follows patients with inflammatory conditions related to infections or immune system problems. Researchers at the National Institutes of Health want to understand these conditions better and may ask you to participate in related studies.
