Vaccines

BACK TO IMMUNOLOGY BACK TO HOST INVASION BY MICROORGANISMS

---

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
