What does variolating mean?
Variolating is the historical medical verb meaning to inoculate someone with material from a smallpox lesion in order to induce immunity. It is the present participle of variolate. The method used actual variola virus rather than cowpox, so it could cause severe smallpox even while producing protection. Practitioners often used material from a smallpox pustule, introducing it through the skin or nose. Variolation was long practiced in parts of Asia and Africa and was also used in Europe before vaccination became the safer standard. Because inoculation with live smallpox could transmit the disease to contacts, the procedure was hazardous as well as valuable. Today variolating is chiefly historical and technical terminology. It should not be confused with violating, which means breaching a law or rule, or with modern vaccination, which uses vaccine material rather than the disease virus itself. The word remains notable as a record of medicine’s gradual movement from deliberate infection toward safer immunization.

Etymology of variolating
English variolate and its inflections come through Latin forms based on variola, meaning “smallpox” or “pock”; variola is a diminutive of varius, “spotted” or “variegated.” Latin variolatus, meaning “pitted” or “pockmarked,” supplied an adjectival base, while the English medical verb came to mean inoculation with variola. The resulting English forms include variolating and variolation.
