Question

Quizplus · Accepted Answer

Passive immunity is acquired from another source and does not involve the individual's immune system. In this case, the newborn infant acquires antibodies from their mother's breast milk while nursing, but this immunity ends when nursing ends. This is in contrast to active immunity, which involves the individual's own immune system producing antibodies, and can be further categorized as either innate or adaptive immunity. Cell-mediated immunity is a type of adaptive immunity that involves specialized immune cells, such as T cells, fighting off infections.
