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

How do antibiotics work?

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.

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

Discussion Question: How do vaccines work?

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.

Discussion Question: What do vaccines trigger in your body?

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

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
