An alphavirus derived replicon particle (RP) vaccine expressing the cluster IV H3N2 swine influenza virus (SIV) hemagglutinin (HA) gene induced protective immunity against homologous influenza virus challenge. However, pigs with maternal antibody had no protective immunity against challenge after vaccination with RP vaccines expressing HA gene alone or in combination with nucleoprotein gene.
