Ontario’s Publicly Funded Meningococcal Immunization Program

August, 2026 - Manufacturers have advised that monovalent conjugate meningococcal serogroup C vaccines (Men-C-C) will no longer be available in Canada. 

  • Ontario will transition to using quadrivalent conjugate meningococcal serogroups A, C, Y, and W vaccines (Men-C-ACYW) for the routine childhood immunization program.  
  • Communication from the Ontario Ministry of Health is linked above.
  • The program change is driven by a discontinuation of Men-C-C vaccines and is not specifically related to changes in provincial meningococcal disease epidemiology but the program change will provide broader protection against additional serogroups (A, Y and W)
  • Providers are asked to:
    • Continue to administer Men-C-C vaccines (Menjugate Liquid and NeisVac-C) until product expiry. 
    • Transition to the use of Men-C-ACYW for those 12 months of age, or as required for catch-up, once all Men-C-C inventory is depleted. 
    • Do not discard usable Men-C-C vaccines prior to expiry.
