Nimenrix (Meningococcal-vaccine) belongs to the family of medications known as vaccines. It is used to prevent infections such as Meningitis, pneumonia, and blood infections caused by the bacteria Neisseria meningitidis groups A, C, Y, and W-135. It works by stimulating the production of antibodies (substances produced by the immune system designed to attack that particular bacteria). These antibodies remain in the body, ready to attack these bacteria, thereby reducing the risk of infection.

It is given to people who are 6 weeks to 55 years of age. It starts to work several days to a few weeks after the vaccine is given.
