Immunization is one of modern medicine’s greatest success stories. Time and again, the international community has endorsed the value of vaccines and immunization to prevent and control a large number of infectious and, increasingly, cancers and other chronic diseases.

Expanding access to immunization is crucial to achieving the Sustainable Development Goals (SDGs). Not only do vaccinations prevent sickness and death associated with infectious diseases such as diarrhoea, measles, pneumonia, polio and whooping cough, they also hold up broader gains in education and economic development.
