===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
 +
