Vaccination and immunisation are two different processes. Vaccination only refers to the administration of a vaccine or toxoid, while immunisation is the process by which the body produces antibodies against the vaccine preventable diseases through administration of speÂ­cific vaccines. These are used to protect us and our domestic animals against viral and bacterial diseases.
