What the trial is, and whether it could suit you
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.
