Chapter 43, Problem 6TYU
Summary Introduction
Introduction: Vaccination is a method of injecting an inactivated bacterial toxin, killed or weakened pathogen. This induces a primary immune response and immunological memory. This method increases the “number of lymphocytes with receptors that can bind to the pathogen”. Hence, the defense mechanism reacts strongly and rapidly during the subsequent invasion of the “pathogen”.

The man is rushed to the hospital and they administer to him anti-rattle snake venom. The anti-rattle snake venom is horse antibodies that were raised against rattle snake venom, and it provides immunity against rattle snake venom. Based on what you studied in the lecture: A) what is the type of immunity that antivenom provides? B) Are the antibodies part of the innate or the adaptive immune responses? C) From what you have learned about the properties of antibodies, can this horse anti-rattle snake venom be used as anti-venom to Cobra snake venom? Explain briefly. D) Six months after this incident, the same person got bitten again by a rattle snake. However, at the hospital the doctors were informed that he was previously given horse anti-venom and so they decided that this person cannot be injected again with horse anti-venom, and they had to find an anti-venom not prepared in horse.
