What meningococcal vaccines are available in the United States?

The vaccines for meningococcal serogroups A, C, W, and Y (MenACWY; Menactra or MenQuadfi by Sanofi; Menveo by GSK) contain meningococcal conjugate in which the surface polysaccharide is chemically bonded (“conjugated”) to a protein to produce a robust immune response to the polysaccharide. Although each of the 3 MenACWY vaccine products uses a different protein conjugate, the products are considered interchangeable; the same vaccine product is recommended, but not required, for all doses.

A discontinued meningococcal polysaccharide vaccine (MPSV4, Menomune, Sanofi) was available in the United States until all doses expired in September 2017. With rare exception, it was not interchangeable with MenACWY conjugate vaccines.

Since late 2014, vaccines have become available that offer protection from meningococcal serogroup B disease (MenB; Bexsero by GSK; Trumenba by Pfizer). These vaccines are composed of proteins found on the surface of the bacteria. These vaccine products are not interchangeable; the same vaccine product is required for all doses.

MenACWY vaccines provide no protection against serogroup B disease, and meningococcal serogroup B vaccines (MenB) provide no protection against serogroup A, C, W, or Y disease. For protection against all 5 serogroups of meningococcus, it is necessary to receive both MenACWY and MenB.
