Share of one-year-olds vaccinated against rotavirus
What you should know about this indicator
- This data represents official WHO/UNICEF estimates of national immunization coverage (WUENIC). The estimates include all WHO Member States, even those that did not report 2023 data. For non-reporting countries, WHO uses statistical methods to extrapolate from previously reported data, ensuring global coverage can be assessed.
- Global and regional vaccination coverage is calculated using population-weighted averages. In 2023, approximately 5% of countries did not report data, requiring extrapolation from their 2022 data to maintain complete global estimates.
- These estimates synthesize multiple data sources: officially reported administrative data (based on health facility reports), coverage surveys that meet WHO quality criteria, and contextual information about vaccine supply disruptions or schedule changes. The quality and reliability of these estimates depend on the completeness and accuracy of country reporting systems.
