Principal Investigator

Year the work was done

2014-2017

Overall objective

  • To investigate ways to enhance prophylactic strategies against avian influenza virus.

Outcomes

  • Pathogen associated molecular patterns (PAMPs) were evaluated and three PAMPs with the ability to enhance and immune capabilities were identified and used as adjuvants for an inactivated AI vaccine.
  • Vaccine formulations that included PAMP and different administration routes for the vaccine were developed.
  • An adenovirus vector for administration of the vaccine was identified, further developed, and used for AI vaccination.

Application

  • A virus vector that can be used for delivery avian influenza virus as well as potentially other avian viruses was developed. This vector has been licensed and is being commercialized.
  • Several combinations vaccine adjuvants in chickens have been identified and have the potential for commercialization.
