What oversight helped Louis Pasteur discover the modern method of vaccination?
One day, Louis Pasteur, who was conducting experiments on the infection of birds with chicken cholera, decided to go on vacation and left his assistant in the laboratory. He forgot to vaccinate the chickens and went on vacation himself. When the assistant returned, he infected the chickens, which weakened at first, but then unexpectedly recovered. Thanks to this oversight, Pasteur realized that weakened bacteria are the key to getting rid of the disease, as they give immunity from it, and became the founder of modern vaccination. Subsequently, he also created vaccinations against anthrax and rabies. 0 reply
