Could catching cow pox prevent people from catching small pox?
I think I can stop you from ever getting smallpox! It won't hurt...much!
Dr Edward Jenner really wanted to conquer the deadly smallpox. One day, he observed Sarah Nelmes, an ordinary milkmaid get infected by cow pox.
Noting that that milkmaids were usually immune to smallpox, Jenner suggested that the pus in the blisters that milkmaids received from cowpox protected them from smallpox.
Jenner tested his hypothesis by infecting James Phipps, an 8-year-old boy. He scraped pus from cowpox blisters on the hands of Sarah Nelmes
Vaccina Dear the British government, The initial source of infection was a disease of horses, called "the grease", which was transferred to cattle by farm workers, transformed, and then manifested as cowpox. If variolation after infection with cowpox fails to produce a smallpox infection, immunity to smallpox has been achieved. Dr. Edward Jenner
Jenner infected Phipps in both arms, giving Phipps a fever but not full-blown infection.
Later, he injected Phipps with smallpox, but no disease followed.
Vaccination was accepted, and in 1840, the British government provided vaccination using cowpox free of charge.
