==Key Stage 4==
===Meaning===
[[Vaccination]] is a method of preventing a future [[infection]] by a [[pathogen]].
===About Vaccination===
: [[Vaccination]] can also be referred to as 'inoculation' and 'immunisation'.
: [[Vaccination]] allows an [[organism]] to become resistant to an [[infection]] before being [[infection|infected]].
: To [[vaccinate]] an [[organism]] a weakened, inert or similar, but less deadly, form of the [[pathogen]] is injected into the [[organism]]. This allows the [[Immune System|immune system]] to create [[antibodies]] to fight the [[infection]] so that when the [[organism]] is [[infected]] by the active version of the [[pathogen]] the [[Immune System|immune system]] already has the [[antibodies]] it needs to destroy it.
===Examples===
: [[Infection|Infecting]] people with [[Cow Pox]] [[virus]] prevents an [[organism]] from getting [[Small Pox]] [[virus]].
: Injecting samples of a weakened version of the [[Tuberculosis]] [[Pathogenic Bacteria|bacterium]] reduces the chance of [[infection]] by 20% and of symptoms developing by 60%.
