First Vaccination (Immunology)
Edward Jenner develops a method to protect people from smallpox by exposing them to the cowpox virus. In his famous experiment, he rubs pus from a dairymaid's cowpox postule into scratches on the arm of his gardener's 8-year-old son, and then exposes him to smallpox six weeks later (which he does not develop). The process becomes known as vaccination from the Latin vacca for cow. Vaccination with cowpox is made compulsory in Britain in 1853. Jenner is sometimes called the founding father of immu -

Antiseptic Principle of the Practice of Surgery
Joseph Lister publishes Antiseptic Principle of the Practice of Surgery, one of the most important developments in medicine. Lister was convinced of the need for cleanliness in the operating room, a revolutionary idea at the time. He develops antiseptic surgical methods, using carbolic acid to clean wounds and surgical instruments. The immediate success of his methods leads to general adoption. In one hospital that adopts his methods, deaths from infection decrease from nearly 60% to just 4%. -

Aspirin is created
Felix Hoffman develops aspirin (acetyl salicylic acid). The juice from willow tree bark had been used as early as 400 BC to relieve pain. 19th century scientists knew that it was the salicylic acid in the willow that made it work, but it irritated the lining of the mouth and stomach. Hoffman synthesizes acetyl salicylic acid, developing what is now the most widely used medicine in the world. https://2020health.files.wordpress.com/2010/12/aspirin.jpg -
