A number of vaccinations are available that offer some protection against meningitis."

According to NHS Choices meningitis is usually caused by a bacterial or viral infection - and can be spread through:

sneezing

coughing

kissing

sharing utensils, cutlery and toothbrushes

Meningitis is usually caught from people who carry these viruses or bacteria in their nose or throat but aren't ill themselves.

It can also be caught from someone with meningitis, but this is less common.
