Scientists seek immune clues from healthy volunteers

NCT ID NCT01132859

First seen Jun 25, 2026 · Last updated Jul 22, 2026 · Updated 6 times

Summary

This study collects blood, tissue, and imaging samples from 500 healthy adults aged 18 and older to learn how the immune system responds to vaccines and natural infections. Participants may provide samples like blood, urine, saliva, or tissue biopsies, and undergo procedures such as bronchoscopy or imaging scans. The goal is to better understand immune protection, which could aid future disease prevention and treatment.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to
If successful, this research could help scientists better understand how the immune system protects against diseases, potentially guiding future vaccine and treatment development.
What could go wrong
This is an observational study, not a treatment trial. It does not test any new drug or therapy, so direct patient benefits are unlikely. Results may take years to translate into practical applications.
