NCT ID NCT06039527
First seen Nov 01, 2025 · Last updated May 21, 2026 · Updated 28 times
Summary
This study aims to understand why older adults, especially frail ones, lose important immune cells (T cells) from their noses, which may make them more prone to lung infections. Researchers will compare nasal samples from 170 healthy young adults, healthy older adults, and frail older adults. The goal is to link these immune changes to infection risk and find clues for future prevention.
