New Phase III data released by Novartis Pharmaceuticals showed that its under-development vaccine against four types of meningococcal strains produces a better antibody response than a commonly used existing vaccine. New Phase III data for Menveo® (MenACWY-CRM) depicts that the vaccine produced a greater immune response against meningococcal strains A, C, W-135 and Y in adolescents aged between 11 and 18 years, as compared to Sanofi Pasteur’s Menactra®. Infection with any of these four vaccine-preventable serogroups (strains) can lead to bacterial meningitis, an infection of the membrane around the brain and spinal cord, or sepsis, a serious infection of the blood stream.
