Submitted by m.nowlan on Mon, 2019-09-02 11:30To provide adequate direct and indirect protection against vaccine-preventable diseases (VPD), a high proportion of the population needs to be immune. Specific immunity against certain diseases can be achieved through immunisation with vaccines or exposure to the pathogen itself. The aim of immunisation programmes is to generate immunity in individuals and within the community to prevent the spread of disease and to reduce the impact of such diseases.
