7.3.5.Role of Vaccines
Vaccines on primary administration sensitises the host and builds up a protective immune response by way of memory cells which persist for a longer time – longevity varies. Natural encounter with the pathogen acts as a booster to the immunity already produced by vaccination. Development of immunity may be systemic or in integumentary organs. It is thus important to demarcate the route of administration of the vaccines |
