==Why Vaccinate?==
===Why Vaccinate?===
*To protect against infectious diseases
*Where there is no effective treatment once infected
**E.g. FeLV, FIV
*Where disease is life-threatening
**E.g. Canine Parvovirus
*To prevent the spread of disease
**E.g. Rabies, FMDV
==How do we vaccinate?==
*Usually by subcutaneous injection for '''systemic''' protection (IgG)
*For '''mucosal''' immune reponse, intranasal administration is best (IgA)
==What do we vaccinate with?==
'''Passive immunisation'''
*Administer antibodies
**Maternally-derived antibodies in colostrum
**Antiserum (artificial)
*Immediate protection
*Short duration of action
'''Active immunisation'''
*Administer antigen so the patient's own antibodies protect against disease
**Living organisms
**Dead organisms
**Toxoids
**Subunit antigens
**DNA
*Delay in protection
*Often needs two or more doses
*Long duration of action
