Vaccination is the best protection against meningococcal serogroup C infections and their complications. For instance, meningitis that is an infection of the brain lining and meningococcemia that is an infection of the blood are two serious infections caused by serogroup C meningococcus.
There are different serogroups or types of meningococcus, among other serogroups A, B, C, W and Y. This vaccine protects against serogroup C.
The Québec Immunization Program has provided for the administration of one dose of the meningococcal serogroup C vaccine at 18 months of age, followed by one dose of a menincococcal serogroups A, C, W and Y vaccine in Secondary 3.
Some symptoms may be caused by the vaccine, e.g. redness at the injection site. Other problems may occur by chance and are not related to the vaccine. e.g. cold, gastro, headache.
Meningococcal serogroup C conjugate vaccine is safe. Most reactions are harmless and do not last long.
