What you should know about this indicator

  • The current release of the WUENIC with data up to 2023 (released in 2024) includes estimates for WHO Member States, including those that did not report 2023 data. For these non-reporting countries, estimates were extrapolated from the last point informed by empirical data.
  • Global and regional coverages, values were extrapolated from 2022 for non-reporting countries.
  • Non-reporting countries represent ≈5% of the global 2023 cohort.
  • These estimates are based on quantitative data: 1) Country reported coverage data (official and administrative coverage) and 2) survey coverage (from survey final reports, and complying with minimum set of quality criteria), and are informed by contextual information (e.g., stock-outs, changes in schedule, and other relevant information where available and appropriate). As such, these estimates are affected by the availability and quality of the underlying data.
  • In countries where the national schedule recommends two doses during infancy and a booster dose at 12 months or later based on the epidemiology of disease in the country, coverage estimates may reflect the percentage of surviving infants who received two doses of PcV prior to the 1st birthday.
