Meningococcal Vaccination:: An Update on Meningococcal Vaccine Recommendations for the Primary Care Physician.

Neisseria meningitidis is an aerobic, gram-negative, diplococcus bacterium that is a leading cause of meningitis and sepsis in the United States. Particularly at-risk groups include those with complement deficiencies, people using complement inhibitors, individuals with anatomic or functional asplenia, patients with HIV infection and travelers to endemic countries. There are currently three quadrivalent meningococcal vaccines (Serogroups A, C, W, Y) and two recombinant serogroup B vaccines available for use in the United States, and recommendations for vaccine use have changed rapidly in the past 10-15 years. This article summarizes updated ACIP recommendations for meningococcal vaccination for the primary care provider.
