PREVENTABLE DISEASES

Vaccine Preventable Diseases

Vaccination against a range of bacterial and viral diseases is an integral part of communicable disease control world-wide. Vaccination against a specific disease not only reduces the incidence of that disease, it reduces the social and economic burden of the disease on communities. Very high immunisation coverage can lead to complete blocking of transmission for many vaccine preventable diseases (VPDs). The world-wide eradication of smallpox and the near eradication of polio from many countries provide excellent examples of the role of immunisation in disease control.
