Question

Quizplus · Accepted Answer

The procedure described refers to vaccination, which involves injecting a harmless microbe (called a vaccine) in order to stimulate the body to produce an immune response (including antibodies) that can protect against a dangerous microbe if encountered in the future. Immunity (choice B) refers to the state of being resistant to infection due to the presence of immune system defenses or previous exposure to a microbe. Antibody modification (choice C) and interferon activation (choice D) are specific immune responses that can occur after exposure to a pathogen, but they do not describe the process of vaccination. Immunoglobulin synthesis (choice E) is another immune response that involves the production of specialized proteins called antibodies, but it is not specific to the process of vaccination.
