Read the excerpt from "Edward Jenner and the History of Smallpox and Vaccination.” However, the most successful way of combating smallpox before the discovery of vaccination was inoculation. The word is derived from the Latin inoculare, meaning "to graft.” Inoculation referred to the subcutaneous instillation of smallpox virus into nonimmune individuals. The inoculator usually used a lancet wet with fresh matter taken from a ripe pustule of some person who suffered from smallpox. The material was then subcutaneously introduced on the arms or legs of the nonimmune person. . . .
