It is a preparation with attenuated viruses of one or more infectious diseases, is inoculated in a healthy person to generate specific antibodies for those diseases and thus immunize him from the natural pathogen. The term was suggested by Louis Pasteur, in recognition of Edward Jenner who christened the disease of variolae vaccinae ("cow smallpox" in Latin) to the disease whose naturally attenuated virus was used to create the first human smallpox vaccine. Thus the Latin voice vaccinae ( "bovine, vaccine, cow" ) ended up associated with the vaccine for immunization.
