NCT ID NCT07357467
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This follow-up study checks if taking TUDCA or fatty acid supplements during a flu vaccine helps older adults (ages 60-70) keep their immunity longer. Researchers will measure antibody levels and immune cells about 8 months after vaccination. No new treatment is given—just one blood draw to see if the supplements boosted long-term protection.
