Share of newborns vaccinated against tuberculosis
What you should know about this indicator
- The WHO recommends BCG vaccination at birth for all newborns in countries or settings with a high incidence of TB and/or high leprosy burden. Countries with low TB incidence or leprosy burden may choose to selectively vaccinate newborns in high-risk groups.
- This chart shows official estimates of national immunization coverage published by the WHO and UNICEF. 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 combine several sources: official administrative data from health facilities, coverage surveys that meet WHO quality standards, and other relevant information like vaccine supply issues or schedule changes. The accuracy of these estimates depends on how complete and reliable each country’s reporting systems are.
