Meningococcal group B (MenB) bacteria can cause serious, life-threatening illnesses including meningitis and septicaemia which can both lead to sepsis. Being around lots of new people in shared living spaces like university halls increases the risk of the bacteria that cause meningococcal disease spreading. Getting 2 doses of the MenB vaccine before the autumn term is one of the most important things young people can do to protect themselves.
