World Immunization Week Hero

Edward Jenner

Edward Jenner (1749–1823) was an English physician and scientist who pioneered the world's first vaccine for smallpox. His groundbreaking work in the late 18th century, observing that milkmaids exposed to cowpox were immune to smallpox, laid the foundation for immunology. Jenner's method of vaccination quickly spread globally, leading to the eventual eradication of smallpox, one of history's deadliest diseases. His legacy continues to inspire modern vaccine development and public health initiatives worldwide.

History of World Immunization Week

Although great strides in inoculation had already been made in Asia and Africa, it was still very risky. Vaccination only really took off in England during the end of the 18th Century after becoming widely understood as a way to prevent smallpox. A patient waiting for her turn to see the doctor made an interesting comment. She remarked that she could not catch smallpox as she already had cowpox. Her comment did not escape the attention of Edward Jenner, a young medical student who was also present. He obsessed over the idea while completing his studies in London.

After graduating, he started practicing medicine in his hometown of Gloucestershire where he would eventually discover that the lady was right. While developing a cure for smallpox, he found that people who had cowpox had fewer chances of getting smallpox. After having successfully conducted the necessary experiments, he went on to give patients a light dose of cowpox to ensure their protection from the horrible plague of smallpox.

Further progress was made In 1798 when Jenner conducted another crucial test. Four children who had been vaccinated with cowpox were now given a weak form of smallpox to protect them against the disease. In support of his theory, not one of them caught smallpox. He made the great discovery of vaccination which today has helped researchers develop various vaccines to prevent life-threatening diseases.
