Chapter 1, Problem 1SEPP

English writer and essayist Lady Mary Wortley Montagu $\left(1689-1762\right)$ traveled extensively and was fascinated by the customs in other countries. While in Turkey, she observed the practice of "engrafting” wherein people were inoculated against smallpox by intentional exposure to a mild form of the disease. She was so convinced of the efficacy and the safety of engrafting, that she had both of her children inoculated. She herself had survived smallpox as a child. Lady Montagu campaigned for the practice when she returned to England, and despite opposition from doctors and religious leaders, inoculation came into common use. It remained the primary defense against the scourge of smallpox for decades—until Jenner developed the practice of vaccination.
