Dr. Petrie’s research interests are based in the epidemiology and transmission of respiratory virus infections. His current projects are focused on the incidence, clinical outcomes, and molecular epidemiology of hospital-associated respiratory virus infections. He is also collaborating on several CDC and NIH funded studies of influenza vaccine effectiveness in inpatient, outpatient and community settings. In addition to estimating influenza vaccine effectiveness each year, recent and ongoing projects have examined the duration of vaccine induced protection, the effects of repeated annual vaccination, and serologic correlates of immunity to influenza infection.
