Question

Quizplus · Accepted Answer

The injection of anti-hepatitis antibodies is an example of artificial passive immunity since the patient is receiving pre-made antibodies rather than producing their own. Natural active immunity would occur if the patient's immune system produced its own antibodies after exposure to the virus. Natural passive immunity would result from the transfer of antibodies from a mother to her baby (such as through breast milk). Artificial active immunity would result from the administration of a vaccine, which stimulates the patient's immune system to produce its own antibodies.
