WHO and UNICEF National Immunization Coverage Estimates Summary
Core Content
The document outlines the methodology and data sources used by the World Health Organization (WHO) and United Nations Children's Fund (UNICEF) to estimate national immunization coverage levels. These estimates are intended to provide a more accurate reflection of immunization system performance, taking into account potential biases and data inconsistencies. The estimates are not based on ad hoc adjustments but are derived from a combination of national reports, survey data, and demographic information.
Main Points
- Estimates are country-specific, with data reviewed individually and not borrowed from other countries.
- Estimates are not based on probability models, so classical measures of uncertainty like confidence intervals are not provided.
- Grade of Confidence (GoC) is used to characterize the level of empirical support for each estimate, not the quality of data reported by national authorities.
- Estimate GoC levels:
- ●●: Well supported by reported data, independent denominator, and at least one supporting survey within 2 years.
- ●: Supported by reported data and independent denominator.
- No accepted empirical data: Estimates based on interpolation or lack of direct data sources.

Data Sources
- Administrative Coverage: Based on aggregated reports from health service providers. May be biased due to inaccurate numerator or denominator data.
- Official Coverage: Estimated by national authorities using a combination of administrative, survey, or other data sources. Varies by country.
- Survey Coverage: Based on population-based household surveys of children aged 12-23 months or 24-35 months. Combines documented evidence or caregiver recall.
Notes on Methodology
- For years where no data are available, interpolation is used between earlier and later years.
- IPV coverage estimates began in 2015 due to the Global Polio Eradication Initiative's Endgame Strategic Plan, which recommended including IPV in routine immunization schedules.
- Estimates are not guaranteed to be accurate and should be used with caution depending on the objective.
- The GoC is a measure of empirical support, not data quality, and is used to indicate the reliability of the estimate.
