1. Which vaccinations have you had?!
Measles, Mumps and Rubella (MMR) vaccine Tetanus vaccine Influenza vaccine HPV vaccine Hepatitis A vaccine Hepatitis B vaccine Rabies vaccine Yellow fever vaccine
We say the vaccination has made you immune to the disease

2. Learning Objectives
State what a vaccine is Describe a graph at GCSE standard Explain what a vaccine is and how it works to give us immunity

3. What’s in a vaccine? Dead pathogen Weakened pathogen
For example: the flu vaccine usually contains 3 strains of dead influenza virus

4. Can you figure out how vaccines work?

5. How vaccinations work
Dead or weakened p……………………. is injected (vaccine) White blood cells make a……………………….. If you are infected later in life your w………………………… recognise the same pathogen White blood cells make antibodies f…………………….. Pathogen is destroyed rapidly as you are i……………………………

6. How vaccinations work
Dead or weakened pathogen is injected (vaccine) White blood cells make antibodies If you are infected later in life your white blood cells recognise the same pathogen White blood cells make antibodies faster Pathogen is destroyed rapidly as you are immune

7. How vaccinations (immunisations) work Vaccines contain….
dead or weakened pathogens
Vaccines prevent infections because…
- White blood cells produce ……………….…. against the dead pathogen
Upon re-infection the antibodies are made much ………………..;
These antibodies ……………… the pathogen before it can cause harm;
Vaccines give your body protection against disease; this is called
immunity
The MMR vaccine protects you against…
Measles, Mumps and Rubella
antibodies
faster
kill

9. Describing graphs at GCSE standard
Describe how the incidence of mumps changes from 1985 to 1995 (3 marks)
Tip
Describe means:
‘say what you see’. Include numbers.
Increase
Go up
Shoots up Rises
Go down Fall
Drops Decrease

10. Describe how the incidence of mumps changes from 1985 to 1995 (3 marks)
The incidence of mumps increases rapidly from to 1987.
It peaks at 14 cases per 100,000 people.
The incidence decreases rapidly from 1987 to and then decreases slowly until 1995.

11. Noughts and Crosses What does a vaccine contain?
What word describes when you are ‘protected’ from a disease?
Explain how vaccines make us immune to a disease.
What does the MMR vaccine protect you against?
Name the three ways that white blood cells defend against pathogens.
How do bacteria cause harm to your body?
When describing a graph what must you do?
Define metabolic rate
Define a pathogen
