Immunization coverage

Description

Immunization coverage is a key measure of immunization system performance

The following pages provide information on the methods, materials and tools used to measure or estimate immunization coverage, and on immunization coverage at the country level based on data reported by countries

Methods
  • the administrative method using reported routine immunization data, i.e. registry system of doses administered
  • immunization coverage surveys using survey methods recommended by WHO. Surveys should be conducted periodically (3-5 years)

The Data Quality Self-Assessment (DQS) is a flexible toolbox of methods used to evaluate different aspects of the immunization monitoring system at district and health unit (HU) levels
