  • Meningococcal B
  • For People with Risk Factors

Are people who are HIV-positive in a risk group for meningococcal disease?

Yes. Studies from the United States, South Africa, and the United Kingdom have shown that people with HIV infection have a risk of invasive meningococcal disease that is 11–24 times higher than the general population. In the United States, this excess risk is specifically for serogroups C, W, and Y. ACIP recommends routine MenACWY vaccination of all HIV-infected people 2 months of age and older. Children younger than age 2 years should be vaccinated using a multidose schedule based upon age (see the document “Meningococcal ACWY Vaccine Recommendations by Age and Risk Factor,” available at for details).

People age 2 years and older with HIV infection who have not been previously vaccinated should receive a 2-dose primary series of MenACWY (doses separated by at least 8 weeks). People with HIV infection who have previously received one dose of MenACWY should receive a second dose at the earliest opportunity (at least 8 weeks after the previous dose) and then receive booster doses at the appropriate intervals. ACIP does not recommend routine meningococcal serogroup B vaccination of people with HIV infection: MenB may be given based upon shared clinical decision-making to people with HIV who are age 16 through 23 years old, preferably between ages 16 and 18 years.
