MenB is short for meningococcal group B bacteria. MenB is one of several types of meningococcal bacteria. The other most common types include W, Y and C.
The MenB vaccine helps protect babies from meningitis and sepsis caused by meningococcal group B bacteria. It does not protect against other types of meningococcal bacteria. Teenagers are offered a different vaccine, called MenACWY, to help protect against types A, C, W and Y.
