Edward Jenner

In the late 18th century, a young English doctor named Edward Jenner made a groundbreaking discovery that would change the course of medical history. Observing that milkmaids who contracted cowpox seemed immune to the deadly smallpox virus, Jenner embarked on a daring experiment. He inoculated a young boy with cowpox and later exposed him to smallpox, proving his theory of vaccination. This revolutionary concept not only saved countless lives but also laid the foundation for modern immunology. Jenner's work ultimately led to the global eradication of smallpox, making him a true pioneer in the field of medicine and earning him the title "Father of Immunology."
