Meningococcal Serogroup C Conjugate Vaccine

Vaccination is the best protection against meningococcal serogroup C infections and their complications. Meningitis (infection of the brain lining) and meningococcemia (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, Y and W135. Serogroup B and serogroup C are the ones found most often in Québec. This vaccine protects against serogroup C.
