Not on topic, just adding perspective
In the 18th Century, a British Physician named Edward Jenner noticed how the local milk maids never seemed to catch small pox; a wide spread disease of the time. He first observed how milk maids never exhibited any scars of previously having had small pox, which left people horribly scarred if they managed to live through it. He then observed milk maids simply never got small pox, but often had smaller, less severe "cow pox" blisters and sores on their hands from milking, which always cleared up and left no scars. He then purposely infected an orphan boy with cow pox by scratching the boy's skin with a needle that had been inserted directly into a cow pox blister from a milk maid. The boy caught cow pox, and quickly recovered as the milk maids did. About a month later, Dr. Jenner infected the young orphan boy with small pox, by scratching the boy's skin with a needle that had been directly inserted into a blister on a person with small pox. The orphan boy never caught small pox!. The very first vaccine ever was discovered! Jenner then vaccinated himself, and his family too, against small pox. He then went through the country side, vaccinated anyone who wanted it, and spared many from dying horrible deaths, or being horribly scarred for life from small pox. Do you want to know what his reward was for inventing a vaccine(the first vaccine ever) against small pox?????
He was stoned to death by the community for practising witchcraft !!!
