You may have already been vaccinated against meningococcal strain C
However, there are actually four vaccine-preventable strains: A, C, Y
and W-135. Strains Y and W-135 have become increasingly common in
Canada, therefore, broad protection against meningococcal meningitis is
something to consider. There is currently no vaccine available to
protect against the fifth strain of meningococcal meningitis, strain B.
