Vaccination is the best protection against meningococcal serogroup B 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 2 serious infections caused by serogroup B meningococcus.
There are different serogroups or types of meningococcus, among other serogroups A, B, C, Y and W135. This vaccine protects against serogroup B.
The vaccine is recommended for persons with a high risk of infection from meningococcus.
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 B vaccine is safe. Most reactions are harmless and do not last long.
