Novel DNA vaccine design offers broad protection against influenza-A H3N2

Researchers developed a novel DNA influenza vaccine based on four micro-consensus antigenic regions selected to represent the diversity of seasonal H3N2 viruses across decades. The DNA vaccine protected mice against a lethal challenge with more than one influenza-A H3N2 virus and protected them from severe H3N2-related illness despite the lack of an exact sequence match between the vaccine immunogen and H3 immunogen. The findings are reported in a new Special Issue on DNA Vaccines in Human Gene Therapy,” a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.
