Immunity means resistant to infection. The picture shows a scientific image of a virus - it looks pretty, but won't do you any good!

Unit 1 - Vaccination

This GCSE Biology quiz explores how vaccination protects the body, using weakened or dead pathogens to train the immune system before a real infection happens.

Fascinating Fact:

White blood cells recognise the antigens in the vaccine and produce specific antibodies to destroy the pathogen.

In GCSE Biology, vaccination is studied as a key method of preventing infectious disease. You learn how vaccines trigger an immune response, create memory cells, and help protect whole communities.

Key Terms

Vaccine: A preparation containing weakened, dead, or modified pathogens used to stimulate immunity without causing the disease.
Antigen: A molecule on the surface of a pathogen that is recognised as foreign by the immune system.
Immunity: Protection against a specific disease, usually due to the presence of antibodies and memory cells.

Frequently Asked Questions (Click to see answers)

What is vaccination in GCSE Biology?

Vaccination is the process of giving a person a vaccine so their immune system learns to recognise a pathogen and respond quickly if they are infected in the future.

How do vaccines help protect the body from disease?

Vaccines introduce harmless forms of a pathogen so white blood cells produce specific antibodies and memory cells, allowing a faster and stronger response to later infections.

What is the difference between vaccination and natural infection?

Natural infection involves catching the disease, which can be dangerous, while vaccination stimulates immunity safely without causing the full symptoms of the illness.

1 .

Which of following describes how antibodies are released after a person has been vaccinated?

Quickly and in large amounts

Slowly but in large amounts

The same as before

Quickly but a different antibody is made

It is important for your immune system to destroy the pathogen before it can reproduce faster than your white cells can destroy it or make it harmless

2 .

White blood cells do not produce which of the following?

Antitoxin

Antibody

Antigen

Immunity

This is the part of the pathogen that triggers your immune system's response

3 .

Pathogens do not include which of the following?

Bacteria

Viruses

Fungi

Plants

Pathogens are usually microorganisms and viruses

4 .

Memory cells are specialised types of which cells?

Red blood cells

Platelets

White blood cells

Nerve cells

Vaccination only works because these cells exist

5 .

Vaccines are very safe for most people, but they can be dangerous for who?

People who are immune

People who are allergic

People who are resistant

People who are ill

Allergy is the most common reason for side effects after a vaccine. It can be very serious and lead to anaphylactic shock

6 .

Which of the following might you find in a vaccine?

Antigens

Neurons

Enzymes

Hormones

Antigens that are not attached to their pathogen pose no risk to the body, however, they will provoke your immune system to produce the correct antibodies to deal with them thus creating immunity

7 .

Which of the following is not a name for white blood cells?

Leucocytes

Lymphocytes

Memory cells

Erythrocytes

This is the scientific name for red blood cells

8 .

Immunity means resistant to what?

Resistant to infection

Resistant to disease

Resistant to cancer

Resistant to invasion

You have a natural immunity to many infections

9 .

Which of the following types of cancer do we have a vaccination for?

Lung cancer

Heart cancer

Cervical cancer

Leukaemia

This is possible because most cases of cervical cancer are caused by a pathogen called the human papilloma virus (HPV), rather than a genetic problem or environmental causes

10 .

Which of the following might you find in a vaccine?

Amoeba

Inactive bacteria

Fungi

Antibiotics

This is just one of the ways in which vaccines are made
