Vaccine for Meningitis

Bacterial meningitis is a serious infection of the protective membranes covering the brain and spinal cord. While it can occur worldwide, certain regions pose a higher risk to travellers. The “meningitis belt” in sub-Saharan Africa, stretching from Senegal to Ethiopia, experiences seasonal outbreaks, especially during the dry season (December to June). During epidemics, the incidence can reach up to 1,000 cases per 100,000 people. Invasive meningococcal disease (IMD), caused by Neisseria meningitidis, is a leading cause of bacterial meningitis in this region and can progress rapidly, sometimes leading to death within 24 hours if untreated.

For Canadian travellers, vaccination is recommended for those visiting high-risk areas, particularly during outbreaks. The quadrivalent meningococcal conjugate vaccine (Men-ACWY) protects against four strains (A, C, W, Y). Canadian children receive the conjugate vaccine in grade 9, which provides protection for up to 5 years. In addition to sub-Saharan Africa, the Hajj and Umrah pilgrimages to Saudi Arabia are associated with increased risk due to large gatherings and close contact among pilgrims. Saudi authorities require proof of Men-ACWY vaccination at least 10 days before arrival for pilgrims, with a validity of up to 5 years for the conjugate vaccine. Travellers should consult with a healthcare provider to determine the appropriate vaccination schedule based on their travel plans.
