Which statement describes artificially acquired passive immunity?

Which statement describes artificially acquired passive immunity?

• A. Short-term immunity via administration of antibodies not produced by the recipient.
• B. Long-term immunity from vaccination.
• C. Naturally acquired immunity.
• D. Immunity after recovery from disease.

Answer: (A)

Artificially acquired passive immunity is protection that comes from receiving antibodies produced outside the recipient. Because the body is not actively making its own immune response, protection appears quickly but lasts only for a short time—the antibodies will eventually degrade and memory cells are not formed. This matches the description of short-term immunity via administration of antibodies not produced by the recipient. Vaccination, in contrast, induces long-term immunity by stimulating the person’s own immune system to produce antibodies and memory cells (active immunity). Naturally acquired immunity results from infection, and immunity after recovery from disease is a natural active process.
