Pfizer Inc. announced results of two Phase 3 studies demonstrating the immunogenicity of TRUMENBA® (Meningococcal Group B Vaccine) against invasive meningococcal B (MnB) strains representative of prevalent strains in the U.S. and Europe. The two studies, one in adolescents and one in young adults, met all primary immunogenicity endpoints. Also, secondary data presented show that TRUMENBA demonstrated similar immune responses against ten additional MnB strains, in both adolescents and young adults. The data, which continue to support the vaccine’s current safety and tolerability profile, were presented at the 34th Annual Meeting of the European Society for Paediatric Infectious Diseases (ESPID 2016).
