Official title
The Effects of Woodsmoke Exposure on Nasal Immune Responses to Influenza Infection in Normal Human Volunteers
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will investigate the effects of woodsmoke (WS) exposure on human nasal mucosal immune responses to viral infection. The study tests the hypotheses that WS exposure modifies biomarkers of nasal mucosal immune function, increases in Live Attenuated Influenza Virus (LAIV) -induced nasal symptoms, and reduces mucosal antibody production.
