Nаme the fаmоus micrоbiоlogist who produced the first lаboratory-developed vaccine: the vaccine for chicken cholera. He happened upon the method of attenuation by accident. In his lab, he was studying fowl cholera by injecting chickens with the live bacteria and recording the illness progression. He had instructed an assistant to inject the chickens with a fresh culture of the bacteria before a holiday. The assistant, however, forgot. When the assistant returned a month later, he injected the chickens with month-old cultures. The chickens, while showing mild signs of the disease, survived. When they were healthy again, they injected them with fresh bacteria. The chickens did not become ill.
