Immunization provides an opportunity to deliver other life-saving measures

Immunization not only protects children from vaccine-preventable diseases. It also serves as an opportunity to deliver other life-saving measures, such as vitamin A supplements to prevent malnutrition, insecticide-treated nets for protection against malaria and deworming medicine for intestinal worms. In addition, the benefits of immunization are increasingly being extended across the life course to include adolescents and adults, providing protection against life-threatening diseases such as influenza, meningitis, and cancers that occur in adulthood.
