Meningococcal Disease and Adults

Adults need to be vaccinated for meningococcal disease if they are at increased risk. This includes college students, military personnel, international travelers to areas where meningococcal disease is endemic, scientists who may be exposed to meningococcal bacteria, adults who have certain types of immune problems, HIV infection, and those without a functioning spleen. (Some children and teens are also at increased risk.)

Healthy adults who got the vaccine as adolescents may not need to be vaccinated again. Adults with an increased risk of meningococcal disease will need booster doses as long as they are still at risk.

There are two types of meningococcal vaccines currently approved for use in the US. Talk with a healthcare professional to determine which vaccines you need.
