What is the difference between vaccination and inoculation?

There is no difference between vaccine and inoculation except for that a vaccine specifically denotes that a portion of the culprit bacteria was used in the formulation of the antidote. For instance, a bit of smallpox is actually introduced into the system in order to build antibodies and immunity to the disease. A vaccination is an inoculation in other words. Some use the terms interchangeably. A vaccine might not be injected but vaccination is.
