Influenza

Influenza Research at the UMN (Areas of research focus, accomplishments and highlights)

• Validation of oral fluids for influenza virus and sensitivity of detection in vaccinated and non-vaccinated populations
• Assessment of the effect of vaccination to reduce influenza transmission
• Assessment of the effect of maternal immunity on influenza spread
• Validation of air collection methods to study airborne influenza in pigs
• Characterization of influenza viruses affecting US swine
