It protects against serogroups A, C, W, and Y. Menomune, has been available since the 1970s. The duration of immunity mediated by Menomune (MPSV-4) is three years or less in children aged under 5 because it does not generate memory T cells. Attempting  to overcome this problem by repeated immunization results in a diminished, not increased, antibody response, so boosters are not recommended with this vaccine.

Meningococcal conjugate vaccine (MCV4):  this vaccine is sold as Menactra, MenHibrix, and Menveo.   Since the introduction of  MACV in 2010, more than 260 million people have been vaccinated across 19 countries. This has resulted in a reduction of the number of meningitis cases by more than 57%. Much work, however, remains to be done to protect the region from meningitis C outbreaks and other types of the disease. The meningococcal conjugate vaccine protects against four types of meningococcal bacteria (called types A, C, W, and Y). In August 2018,  Nigeria introduced the Meningitis A Conjugate Vaccine into the routine Expanded Programme on Immunization (EPI) schedule.

Serogroup B meningococcal vaccine: This vaccine is  sold as Trumenba and Bexsero and licensed for people 10 years or older who are at increased risk for serogroup B meningococcal infections.It  protects against serogroup B. These vaccines are recommended routinely for people 10 years or older who are at increased risk for serogroup B meningococcal infections, including:

  • People at risk because of a serogroup B meningococcal disease outbreak
  • Anyone whose spleen is damaged or has been removed
  • Anyone with a rare immune system condition called ”persistent complement component deficiency”
  • Anyone taking a drug called eculizumab (also called Soliris®)
  • Microbiologists who routinely work with N. meningitidis isolates
  • These vaccines may also be given to anyone 16 through 23 years old to provide short term protection against most strains of serogroup B meningococcal disease; 16 through 18 years are the preferred ages for vaccination.
