During the mid- to late 19th century Pasteur demonstrated that microorganisms cause disease and discovered how to make vaccines from weakened, or attenuated, microbes. He developed the earliest vaccines against fowl cholera, anthrax, and rabies.
How did Edward Jenner contribute to medicine?
Jenner, a country physician, invented vaccination with cowpox to replace the fearful dangers of inoculation with smallpox. This development resulted in immunity to smallpox and ushered in the era of preventive measures for contagious diseases (World Health News.
