NCT ID NCT05536219
First seen Nov 01, 2025 · Last updated May 14, 2026 · Updated 25 times
Summary
This study looks at whether certain people have natural antibodies that block their immune system's first line of defense against viruses. Researchers will measure viral levels in nose samples from 360 adults and children in intensive care with severe flu, RSV, or COVID-19. The goal is to understand why some people get very sick and whether these antibodies lead to higher viral loads and slower recovery.
