Edward Louis Jenner

Edward Louis Jenner was an English physician best known for developing the smallpox vaccine in the late 18th century. His work was pioneering in the field of immunology, as he discovered that using material from cowpox sores could protect people from smallpox, a deadly disease at the time. Jenner’s innovation laid the foundation for modern vaccination and greatly contributed to global health efforts to control infectious diseases. His scientific approach and careful experimentation marked a significant advance in understanding how immunity works and transformed medicine's ability to prevent illnesses.
