Sense: verb/1

For disease protection, inoculate is more formal than vaccinate and often appears in technical, historical, or public-health writing. Vaccinate is the everyday word people use for giving a vaccine, especially when they talk about children, pets, or travel. Immunize is broader and can stress the protection achieved, not only the act of giving the material. Inject is wider still: it only describes putting something into the body with a needle, so you can inject pain medicine without protecting against a disease. A clinic may vaccinate a child, a report may say a village was immunized, and a lab paper may describe animals being inoculated with a vaccine strain.

Etymology

LatinEnglish

Inoculate comes from the Latin verb inoculare, which first meant putting a bud into a plant by grafting. English later used the same image for putting living material into a body to create protection from disease. From that medical sense, the verb also developed figurative uses about giving someone a small early dose of trouble or planting an attitude in the mind.
