1. Warm up:
How do antibiotics/vaccines help us from getting sick?

2. How do antibiotics work?

3. Antiseptics – chemicals like soap, vinegar, rubbing alcohol, that kill pathogens.
Antibiotics – medicines that target bacteria or fungi and keep them from growing or reproducing.
Example: Penicillin makes bacteria unable to form cell walls.

4. Goal/Objective
Explain how vaccination protects an individual from infectious diseases

5. Discussion Question:
How do vaccines work?

6. KEY CONCEPT
Vaccines help a person build immunity and stay healthy.
Immunity refers to an individual’s ability to fight off a pathogen with the antibody-based specific immune response.

8. Discussion Question:
What do vaccines trigger in your body?

9. Vaccines produce immunity to pathogens.
Vaccines contain the antigen of a weakened pathogen.
Antigen results in antibody production

10. How vaccination provides immunity:
Antigens in a vaccine trigger an immune response, and memory B cells are made. 1
memory B cells
stimulates a specific immune response
causes antibodies and memory cells to be produced
A memory B cell is stimulated when the real pathogen binds to it. 2
allows immune system to respond quickly to infection when a person is exposed to the real pathogen later in life
The B cell quickly activates and makes antibodies that fight the pathogens before you get sick. 3

11. What are some common vaccines?

13. Research 3 vaccines and list 1) What they are for 2) How they work
Class Work:
Research 3 vaccines and list
1) What they are for
2) How they work
3) Any risks involved in using them.
Turn it in when you are finished.
