How does vaccination protect you against disease?
Your white blood cells produce antibodies to destroy the pathogens. Then your body will respond rapidly to future infections by the same pathogen, by making the correct antibody. You become immune to the disease.

What is an antibody and what cell produces them?
An antibody is a protein produced by the white blood cells to fight disease.
2 of 7
What is active immunity?
Active immunity is when the vaccine triggers the immune system to produce antibodies against the disease as though they are being infected with it.
3 of 7
What is passive immunity? Why do new born babies have immunity?
Passive immunity is when immunity is passed on passively. New born babies have immunity because antibodies have been passed down from their mother.
4 of 7
What three ways that a pathogen can be altered to produce a vaccine?
1. Weakening it by growing it repeatedly so it is less dangerous. 2. Taking out the part of the pathogen that causes the immune response and using this in the vaccine. 3. Using the toxin that the pathogen makes and inactivating it.
5 of 7
What are the advantages of vaccination?
In some cases vaccines provide lifelong protection from a disease and you will be protected from serious/life threating diseases. Giving people vaccinations will eventually wipe out that disease.
6 of 7
What are the disadvantages of vaccination?
The vaccine could cause side effects. You could be allergic to the vaccination. Some vaccines are not so effective and do not give you lifelong protection.
