What is the significance of using a hyperimmunized animal in antitoxin production?

Using a hyperimmunized animal in antitoxin production is significant because it increases the concentration of antibodies that are produced in response to a specific antigen. Hyperimmunization involves administering several doses of an antigen or a series of vaccines over a period of time, which stimulates the animal's immune system to produce a robust and heightened immune response. As the animal is exposed repeatedly, its immune system becomes more effective, leading to a higher titration of antibodies in its serum. This concentrated source of antibodies is then harvested to produce antitoxins that can be administered to other animals or humans for passive immunity against specific toxins or pathogens.

While the other options may have relevance in different contexts—such as cost considerations or ensuring efficacy—these factors are not the primary significance of hyperimmunization in the context of generating a potent antitoxin. The core goal is to maximize antibody concentration, which is crucial for effective antitoxin therapy.
