In the field of epidemiology, antitoxins play a crucial role in both the treatment and prevention of toxin-mediated diseases. They are invaluable in outbreaks of diseases like diphtheria and botulism, where rapid neutralization of the toxin can save lives. Epidemiologists also study the effectiveness of antitoxins in various populations and monitor the incidence of diseases that can be treated with antitoxins to ensure adequate supply and distribution.
