Hi Abbie,

Vaccines work because once you body has dealt with an infection, it it better prepared to deal with other infections.

A vaccine give your body a weaker version of an infection and once your body has dealt with that, it can deal with the stonger version of the infection.

Full details are given in the section below....hope that helps :)
