Meningococcal group B (MenB) - Information for health professionals

On this page



Meningococcal is a notifiable disease, which most commonly presents as either meningitis or septicaemia, or a combination of both, or conjunctivitis. In the UK, meningococcal infection is most often caused by the bacterium Neisseria meningitidis group B, although other serogroups can also cause disease. The incidence is highest in children under one year, and also ages 16 – 24 years. The organism is spread by respiratory droplets and has an incubation period of two to seven days.


In September 2015 a four component meningococcal B (4CMenB) protein vaccine, Bexsero was introduced for infants at two, four and 12 – 13 months of age as part of the routine childhood programme.

Bexsero is an inactivated injectable vaccine in a pre-filled syringe presentation. Bexsero is an rDNA component adsorbed vaccine.

The MenB vaccine is effective against serious infections caused by meningococcal group B bacteria. The vaccine may also protect against infection by capsular groups other than group B.
