IMMUNOLOGY

Detailed explanation-1: -Vaccines contribute to active immunity by providing us with a controlled way to create an immune response. When a vaccine is introduced, our immune system treats it like any other exposure. It works to stop the “assault” and, in the process, immunologic memory develops.

Detailed explanation-2: -If you’re wondering why vaccine-induced immunity is considered a form of active immunity, while immune globulin shots are passive, it is because immune globulin is a substance made up of antibodies that are naturally made by the body to provide protection from certain diseases.

Detailed explanation-3: -Examples of active immunity include a person’s resistance to strep throat due to a previous infection or a person’s immunity to polio due to the polio vaccine. Types of active immunity can either be natural active immunity or artificial active immunity.
