Passive artificial immunity is obtained by

• A. True
• B. False
• C. Only from vaccination
• D. Only from maternal antibodies

Answer: (A)

The main idea is that passive artificial immunity comes from giving someone preformed antibodies from another source. This provides immediate protection or treatment because the body doesn’t have to make antibodies on its own, but the protection is temporary since no immune memory is established in the recipient. Examples include immune globulins or antivenoms given after exposure to a toxin or pathogen (like rabies immune globulin or hepatitis B immune globulin, and various antivenoms). Because the protection is due to externally supplied antibodies, there isn’t a lasting immune memory in the person who receives them. This differs from vaccination, which builds active immunity by stimulating the person’s own immune system to produce antibodies and memory cells—leading to longer-lasting protection. It also differs from natural passive immunity provided by maternal antibodies transferred during pregnancy or through breast milk, which is a natural form of passive protection rather than an artificial one. So the statement is true: passive artificial immunity is obtained by administering preformed antibodies from an external source.
