Serum therapy and passive immunity marked a milestone in serology. Emil von Behring and Shibasaburo Kitasato showed that immune factors in blood could neutralize toxins by developing a diphtheria antitoxin from immunized animals and using it to treat humans. The therapeutic product they introduced is the diphtheria antitoxin, a serum-based preparation that binds and neutralizes the diphtheria toxin, reducing mortality during outbreaks. This work established the foundation of modern serology and immunotherapy. The other options don’t fit because penicillin is an antibiotic, insulin treats diabetes, and a polio vaccine prevents disease rather than providing toxin-neutralizing serum therapy.
