_______ is Borrowed Immunity, So Its Effects Do Not Last

Question

_______ is borrowed immunity, so its effects do not last.
A) Passive immunity
B) Active immunity
C) Immunization
D) Primary response

Accepted Answer

Passive immunity is borrowed from another source, such as antibodies passed from mother to fetus during pregnancy or through breast milk. Because the antibodies are not produced by the person's own immune system, the effects are temporary and do not last long-term. Active immunity, on the other hand, is when the body produces its own antibodies in response to an infection or vaccination, providing long-term protection. Immunization is a process of inducing active immunity. Primary response refers to the initial immune response to an antigen.
