Dr. Edward Jenner was a man who has saved millions of lives due to his discovery of cowpox as the most effective treatment for the killer disease of smallpox.

Born in 1749, he was orphaned at the age of five years, his parents both dying within two months of each other in 1754. He was sent away to boarding school at the age of eight years, and whilst there was subjected to be inoculated with a small amount of smallpox which was the standard treatment of the day, although it was a matter of luck as to whether the patient survived or not. He suffered side effects that haunted him to his dying day.

Luckily for us, he survived his ordeal, and as an adult, he dedicated his life to finding a more effective and much safer cure for smallpox and despite a great deal of opposition from some of his medical colleagues, found the cure and in 1980, the World Health Organisation officially announced that smallpox had finally been eliminated.

There is a statue of him in Gloucester Cathedral and sadly visitors to the cathedral know little or nothing about him. As the 200th anniversary of his death in 1823 approaches, this book attempts to show the reader how much we owe him.
