This indicator measures a government’s commitment to providing essential public health services and reducing child mortality.
Relationship to Growth & Poverty Reduction
The Immunization Rates indicator is widely regarded as a good proxy for the overall strength of a government’s public health system. 1 It is designed to measure the extent to which governments are investing in the health and well-being of their citizens. Immunization programs can impact economic growth through their broader impact on health. 2 Healthy workers are more economically productive and more likely to save and invest; healthy children are more likely to reach higher levels of educational attainment; and healthy parents are better able to invest in the health and education of their children. 3 Immunization programs also increase labor productivity among the poor, reduce spending to cope with illnesses, and lower mortality and morbidity among the main income-earners in poor families. 4
MCC uses the simple average of the national diphtheria-pertussis-tetanus (DPT3) vaccination rate and the measles (MCV) vaccination rate. The DPT3 immunization rate is measured as the number of children that have received their third dose of the diphtheria, pertussis (whooping cough), and tetanus toxoid vaccine divided by the target population (the number of children surviving their first year of life.) The measles immunization rate is measured as the number of children that have received their first dose of a measles-containing vaccine divided by the same target population.
To estimate national immunization coverage, WHO and UNICEF draw on two sources of empirical data: reports of vaccinations performed by service providers (administrative data) and surveys containing items on children’s vaccination history (coverage surveys). Surveys are frequently used in conjunction with administrative data; in some instances—where administrative data differ substantially from survey results—surveys constitute the sole source of information on immunization coverage levels. There are a number of reasons survey data may be used over administrative data; for instance, in some cases, lack of precise information on the size of the target population (the denominator) can make immunization coverage difficult to estimate from administrative data alone. Estimates of the most likely true level of immunization coverage are based on the data available, consideration of potential biases, and contributions of local experts.
In consultation with the WHO, MCC considers Scorecard LMICs with immunization coverage above 90% to be passing this indicator. Scorecard LICs that score above the median are considered to be passing this indicator.[[MCC uses the World Bank’s historical ceiling for IDA eligibility to divide countries into assessment categories. Scorecard LICs are countries that fall below the ceiling (GNI per capita of $0-$1,945 for FY17) and Scorecard LMICs are countries above the ceiling but below the World Bank’s LMIC cut-off (GNI per capita of $1,946-$4,035 in FY17.)]]
