The Treatise on Smallpox and Measles

The "Treatise on Smallpox and Measles" is a detailed medical work from the 18th century by Edward Jenner. It explains how these infectious diseases spread, their symptoms, and their dangers. Jenner is famous for developing the smallpox vaccine, which used cowpox to protect against smallpox. The treatise laid important groundwork for understanding how vaccines work and helped promote smallpox prevention, ultimately leading to the disease's eradication. It represents a significant step in the history of immunology and public health.
