Scientists investigate why COVID-19 hits older adults harder
NCT ID NCT04565067
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at blood samples from 83 adults in Maryland who have recovered from COVID-19. Researchers want to understand how specific immune cells called CD8 T cells respond to the virus and how this changes with age. The goal is to gather knowledge that could help create better vaccines for older adults.
