 * 3.2 Jenner's Famous Experiment** page 111

Jenner created an experiment in which he took an eight-year-old boy and placed him near infected cows so he would get cowpox. Just after the boy recovered, Jenner infected him with smallpox. Just as he thought, the boy did not show any symptons of smallpox. This risky experiment help him discover that getting cowpox would prevent a person from getting the deadlier disease, smallpox. Once people found out about this discovery, they started purposely infecting themselves with the cowpox to prevent them of future smallpox infection. Jenner's experiment would be considered way to risky to perform today.
