New vaccine boosts hopes of eliminating meningitis across Africa
A trial of a new vaccine against meningococcal disease, a cause of meningitis and blood poisoning, has found that it is safe and induces a strong immune response across five strains of meningococcal bacteria: A, C, W, Y and X. The phase 3 trial compared the immune response generated by the new pentavalent vaccine NmCV-5 against that of the licensed quadrivalent MenACWY-D vaccine in 1,800 healthy 2-29-year-olds in Mali and The Gambia.
