Invasive meningococcal disease caused by Neisseria meningitidis presents a significant public health concern. Meningococcal disease is rare but potentially fatal within 24 hours of onset of illness, and survivors may experience permanent sequelae. This review presents the epidemiology, incidence, and outbreak data for invasive meningococcal disease in the United States since 1970, and it highlights recent changes in vaccine recommendations to prevent meningococcal disease. Relevant publications were obtained by database searches for articles published between January 1970 and July 2015. The incidence of meningococcal disease has decreased in the United States since 1970, but serogroup B meningococcal disease is responsible for an increasing proportion of disease burden in young adults. Recent serogroup B outbreaks on college campuses warrant broader age-based recommendations for meningococcal group B vaccines, similar to the currently recommended quadrivalent vaccine that protects against serogroups A, C, W, and Y. After the recent approval of two serogroup B vaccines, the Advisory Committee on Immunization Practices first updated its recommendations for routine meningococcal vaccination to cover at-risk populations, including those at risk during serogroup B outbreaks, and later it issued a recommendation for those aged 16-23 years. Meningococcal disease outbreaks remain challenging to predict, making the optimal disease management strategy one of prevention through vaccination rather than containment. How the epidemiology of serogroup B disease and prevention of outbreaks will be affected by the new category B recommendation for serogroup B vaccines remains to be seen. [ABSTRACT FROM AUTHOR] |
