Data from a Phase 3 trial of a combination vaccine candidate to prevent meningococcal disease, a bacterial infection that can cause death or permanent disability, were positive, according to the developer GSK Plc. The vaccine candidate showed non-inferiority in primary endpoints for five Neisseria meningitidis serogroups compared with Bexsero and Menveo, two marketed GSK vaccines, which together cover the same serogroups. The five Neisseria meningitidis serogroups account for nearly all invasive meningococcal disease cases in the world.
