Vaccination

Vaccination

1. injected with vaccine- small amount of dead or inactive pathogen

2. white blood cells detect the antigens on the dead or inactive pathogens

3. antibodies attach themselves to the dead or inactive pathogens and kill them

4. white blood cells memorise the antigen

5. live pathogens enter the body

6. white blood cells recognise the pathogens as they have the same antigens

7. create antibodies to fit antigens

8. antibodies attach and kill them before you feel ill
