Working as a physician in rural England, he noted the observation that people who had contracted cowpox in rural communities were less susceptible to smallpox. Medicine in the 18th century evolved between empirical knowledge and experimentation.
In 1796, he experimented with inoculation using cowpox and demonstrated the possibility of preventing smallpox. Smallpox spread throughout the world and became an important basis for later vaccine concepts and public health policy.
Although there had been attempts to prevent smallpox before Jenner, he systematically demonstrated the effectiveness of cowpox inoculation and made it widely available. The history of medicine is an example of how observation and practice changed society.
By studying Jenner, we can understand the process by which infectious disease countermeasures developed not just as treatment for individuals, but also as preventive policies for society as a whole. He was the starting point of the long history of public health that led to the eradication of smallpox, and collaboration between science and government is also considered.
