Question

Quizplus · Accepted Answer

Vaccination is a prophylactic measure because it involves the administration of a weakened or inactivated form of a pathogen or a part of it to stimulate the immune system to produce antibodies against it. This prepares the immune system to recognize and destroy the pathogen in case of future exposure, thus preventing infection. Artificial passive immunity (choice B) and antiserum injection (choice C) are not prophylactic measures but rather therapeutic measures used to treat an ongoing infection.
