Vaccinate \Vac"ci*nate\, v. t. [imp. & p. p. {Vaccinated}; p.
pr. & vb. n. {Vaccinating}.] [See {Vaccine}.]
To inoculate with the cowpox by means of a virus, called
vaccine, taken either directly or indirectly from cows; now,
generally, to administer (by injection or otherwise) any
vaccine with the objective of rendering the recipient immune
to an infectious disease. One who has been thus immunized by
vaccination is said to be

{vaccinated against} a particular disease. One may be thus
immunized (vaccinated) also by oral ingestion or
inhalation of a vaccine.
