innoculate or inoculate?Innoculate - to introduce to a person or animal some kind of active disease agent causing a mild form of something and so stimulating immunity to a more severe form.
Vaccinate - was originally to inoculate using cowpox virus to prevent smallpox, now used more generally.
Immunize - to make a person or animal immune to a disease, for example.
The current programmes in the UK are referred to as vaccination and immunization.
That may have been the original definition, but "vaccination" has expanded to include injected vaccines as well. As a vaccine by definition is a preparation of killed or weakened organisms, I think that is what determines if it is called a "vaccination", and not the method of introducing the vaccine into the body.Surely "vaccination" is typically regarded as the introduction of a vaccine by rubbing it into a scratch, whereas inoculation would indicate that the substance to be introduced would be injected through the skin to various depths.
