About Vaccination
- Vaccination can also be referred to as 'inoculation' and 'immunisation'.
- Vaccination allows an organism to become resistant to an infection before being 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 to create antibodies to fight the infection so that when the organism is infected by the active version of the pathogen the immune system already has the antibodies it needs to destroy it.
