Edward Jenner was an English physician known for his pioneering work in immunology. In 1796, he conducted experiments that led to the development of the smallpox vaccine, which involved inoculating a boy with material taken from cowpox lesions. This groundbreaking study demonstrated that exposure to cowpox could provide immunity to smallpox, ultimately leading to the successful eradication of the disease. Jenner's work laid the foundation for modern vaccination practices.
