Meningococcal vaccine evolution

Abstract

Neisseria meningitidis is a leading cause of bacterial sepsis and meningitis worldwide. Although polysaccharide and glycoconjugate vaccines have been developed for serogroups A, C, Y and W-135, currently there are no broadly effective vaccines available for the prevention of meningococcal B disease. A general overview of the burden of the disease and the strains prevalence in the world with the focus in particular on the Italian situation is provided in this article, together with the vaccinations developed and under evaluation.
