First seen Nov 01, 2025 · Last updated May 19, 2026 · Updated 25 times

Summary

This study looks at how approved seasonal flu vaccines affect the body's immune response, specifically antibodies and memory B cells, in younger adults (ages 18-50) and older adults (ages 65-80). Researchers aim to understand how age and past vaccination history change the way the immune system reacts to the flu shot. The study involves 50 participants and does not test new treatments, but rather gathers knowledge to improve future vaccine strategies.
