An individual bitten by a rabid dog can be treated by an injection of human rabies antibodies.The type of immunity provided by this treatment is
Correct answer: D. Artificial passive
- A. Natural active
- B. Natural passive
- C. Artificial active
- D. Artificial passive
Explanation
The correct answer is artificial passive immunity. This type of immunity occurs when antibodies are directly introduced into the body, providing immediate protection without the body having to produce its own antibodies. In this case, the injection of human rabies antibodies provides immediate protection against the rabies virus, without the person's immune system actively responding to the pathogen.Other options are incorrect: Natural active immunity involves the body producing antibodies after exposure to a pathogen naturally; natural passive immunity involves naturally transferred antibodies, such as those from a mother to her baby; and artificial active immunity involves vaccination, where the body actively produces antibodies in response to an introduced antigen.

About Specific Defense Mechanism
Specific defense mechanisms provide targeted immunity through B lymphocytes, T lymphocytes, antibodies and memory cells that recognize particular antigens. Questions cover humoral and cell mediated responses, clonal selection, primary and secondary immune responses, vaccination and passive immunity, while distinguishing adaptive defenses from the immediate, non specific innate response.
