Influenza A viruses cause highly contagious diseases in a variety of hosts， including humans and pigs. To develop a vaccine that can be broadly effective against genetically divergent strains of the virus， in this study we employed molecular breeding (DNA shuffling) technology to create a panel of chimeric HA genes.
