Vaccination Immunization

Vaccines And Immunisation

Vaccines are used to immunise people against infectious diseases, such as polio, hepatitis and whooping cough. Immunisation helps prevent diseases that can cause illness, severe disability or even death. For some diseases, immunising the whole population can eradicate the disease completely (as with smallpox) or make it very rare.
