Technical Abstract:
Recently, the 2009 human H1N1 influenza virus was identified in turkey breeders in Chile, Canada and the U.S. resulting in infection and production losses. In these studies sera from turkeys vaccinated against avian influenza H1 were tested against the recent human pandemic H1N1 virus. Genetic analysis demonstrated 92 percent nucleotide similarity in hemagglutinin gene sequences between avian and human H1N1. High levels of HI antibody were observed against the homologous avian vaccine viruses, while minimal cross reaction was observed against the human H1N1. Taken together, the current turkey H1N1 vaccines may have limited cross protection against the human pandemic H1N1.
