Pasteur was a pioneer in the field of germ theory. In 1881, the inventor of pasteurization perfected a way to isolate and weaken germs, and he went on to develop a vaccine against anthrax in sheep. He soon turned his attention to researching rabies. In 1885, he inoculated a 9-year-old boy who had been badly mauled by a rabid dog. The vaccine likely prevented the boy from contracting rabies, which then meant certain death. How did Pasteur’s chickens accidentally get vaccinated against cholera? Discuss
