Meningitis is an infection of the protective membranes that surround the brain and spinal chord. It can affect anyone but is most common in babies, young children, teenagers and young adults.
It can cause life-threatening sepsis and result in permanent damage to the brain or nerves.
There are a number of vaccinations than offer some protection against meningitis.
This NHS Meningitis webpage provides more information, including details of symptoms, vaccinations and other treatments.
