Learning objectives

3.5.8 You can describe how antibodies protect against infection.

3.5.9 You can describe how immunity is created.

3.5.10 You can describe what happens in the event of an allergic reaction.

Immunity

What do you call the micro-organism causing the disease?

1. Antibody
2. Antigen
3. Infection
4. Pathogen

An antibody is used to fight antigens and thus kill the pathogen

1. what is vaccination?

2. Did you get all your vaccinations as a child?

3. What is your opinion about vaccinating?

Immunity I

A pathogen is a micro-organism causing a disease.

The foreign body (protein on the outside of a micro-organism) is called an antigen.

In order to kill a pathogen, antibodies are produced by white blood cells (memory cells). 

Every antigen is unique and only one antibody will match.

immunity II

immune is not getting sick because white blood cells can make antibodies almost immediately for a pathogen you have previously been infected with.

Immunity can be obtained naturally (after contracting the disease) or artificially  (via vaccination.

Immunity can be obtained actively  (via giving someone antibodies) or passively (the body producing the antibodies).

Natural, active immunity

Artificial, active immunity

Natural, passive immunity

artificial, passive immunity

Antibodies made after exposure to an infection

Antibodies transmitted from mother to baby

Antibodies made after getting a vaccination

Antibodies acquired from an immune serum medicine

Note!

Immunity III

Immunity coverage is the percentage of people who have to be vaccinated if the population as a whole is to be protected against a disease.

Portfolio

1. Create a summary (you may use the summary exercise from the book)
2. Write down 2 questions to test your knowledge about vaccination
3. Put the note about the types of immunity in your portfolio including examples
4. send your portfolio to me (Marjolein Coppens) via teams

If you are done, start questioining each other with the exam questions from your portfolio.
