Question

Quizplus · Accepted Answer

The purpose of a vaccine is to elicit an active immune response. This means that the vaccine introduces a harmless version of a pathogen to the body to stimulate the immune system to produce specific antibodies and immune cells. This way, if the person is later exposed to the actual pathogen, their immune system is already prepared to fight it off, providing immunity to the disease. Vaccines do not cure the disease, cause a fever, or kill infected cells. They are designed to help the body build immunity to prevent future illness.
