LOUIS PASTEUR SUMMARY
Born on December 27, 1822 Louis Pasteur was a French Biologist. He is renowned for his discoveries of the principles of Vaccination. This story is about Louis Pasteur, He found a cure for rabies, which was considered as one of the deadliest diseases of the 19th and 20th centuries.
Lets’s Read the story
One Day when Louis Pasteur was playing with his friends. Suddenly he saw a man strangely running towards him. He was very frightened, Louis asked him the reason for his such behavior. The man replied that “Someone has been bitten by a mad wolf from the mountain”. Louis understood that the mad wolf was suffering from rabies.
If you don’t know, Rabies is a viral disease that causes inflammation of the brain in humans and other mammals. Animals with this viral disease get Mad. This viral is can be spread to humans also if human beings are bitten by animals with rabies.
Many years later, after that incident. Louis Pasteur started experimenting to discover the vaccine for this disease. He started his experiments on rabbits. In his experiments, he treated rabbits by injecting them with the same virus and he succeeded in curing them. After this successful experiment on rabbits, he thought to try it on human beings. And that chance came on 6 July 1885, when a boy was returning from school was bitten by a Mad dog. Her mother came to Pasteur to seek help She started crying. Louis Pasteur answered her that he is ready to give everything he had.
As the vaccine which was used on rabbits was successful but Pasteur was not sure about the outcome of the same vaccine when used on human beings. He thought that if it works it will benefit the entire human race in the future. Thinking this he made up his mind to take the risk. He injected the boy with the virus. After injecting the virus Pasteur Kept him under observation, the result which came was very surprising, the boy responded to Pasteur’s treatment. It was a huge achievement for Pasteur and a great discovery for the human race. This new method of treatment of rabies made Pasteur famous all over the world.
