Postgenomics of Neisseria meningitidis for vaccines development

Abstract

Meningococcal disease is a global problem. Multivalent (A, C, Y, W135) conjugate vaccines have been developed and licensed; however, an effective vaccine against serogroup B has not yet become available. Outer membrane vesicle (OMV) vaccines have been used to disrupt serogroup B epidemics and outbreaks. Postgenomic technologies have been useful in aiding the discovery of new protein vaccine candidates. Moreover, proteomic technologies enable large-scale identification of membrane and surface-associated proteins, and provide suitable methods to characterize and standardize the antigen composition of OMV-based vaccines.
