MenACWY, or meningococcal conjugate, protects against meningococcal disease caused by serogroups A, C, W, and Y. A different meningococcal vaccine, meningitis B or meningococcal B, is available that can help protect against serogroup B.

If documentation of your meningitis vaccine does not clearly indicate it is MenACWY or meningococcal conjugate, you will not be considered fully vaccinated for meningitis A, C, W, and Y serotypes. Common brand names of the MenACWY vaccine in the US are Menactra, Menveo, and MenQuadfi.
