Influenza B virus is an important cause of acute upper respiratory disease in humans. Vaccination is the primary method of control of influenza related disease, yet vaccine methodology and production technology have not changed in over 40 years. In this study, we compare the efficacy of recombinant baculovirus produced protein based neuraminidase containing influenza B vaccines with conventional inactivated influenza vaccine (CIV) and live-attenuated influenza vaccine (LAIV) in a murine model. All HA containing vaccines stimulated antibody and protected against an infectious challenge with homotypic virus (B/Harbin/7/94), only recombinant protein based (rHA + rNA and rNA) vaccines containing immunogenic amounts of influenza neuraminidase (NA) protected against challenge with a significantly antigenically different heterovariant virus (B/Beijing/243/1997), as measured by a reduction in mean pulmonary virus titers. This report demonstrates with influenza B virus, in a side-by-side comparison with CIV and LAIV in a murine model system the superiority of vaccines containing immunogenic NA over currently approved CIV and LAIV vaccines. |
