Nasal shields aim to stop COVID and flu before they start
NCT ID NCT07516977
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests two nasal protective devices (Noseguard and Noseguard Night) in 2000 adults to see if they can reduce the risk of catching respiratory infections like COVID-19 and influenza. Participants will use the devices as directed for 8 weeks, and researchers will track infection rates, usability, and safety through electronic surveys. The goal is to find a simple, non-drug way to prevent common respiratory illnesses.
