Introduction: Neisseria meningitidis infections represent a serious health problem that can lead to invasive meningococcal disease (IMD), a life-threatening condition associated with significant morbidity and mortality. IMD could however be preventable via vaccination. During the past five decades, vaccines against N. meningitidis capsular groups A, C, W and Y were introduced into the market. Recently, group B vaccines based on N. meninigitidis recombinant antigens and outer membrane vesicles have been developed and novel vaccine candidates are under evaluation. Areas covered: In this review we discuss the main meningococcal vaccines available, with focus on immunogenicity data, vaccination impact on disease burden and persistence of vaccine-induced immune response. Preliminary results on new vaccine formulations, potentially able to provide multi-group coverage, are also reported. Expert commentary: Continuous surveillance and optimization of national immunization programs are required in order not only to promptly fight future outbreaks but also to identify possible changes in N. meningitidis epidemiology.
