WHO and UNICEF estimate immunization coverage in Türkiye for the 2021 revision based on data up to July 7, 2022. Coverage estimates are derived from national reports, surveys, and administrative data, with grades of confidence indicating data reliability: ••• for well-supported estimates, •• for some data support, and • for limited or challenged data. Overall, coverage remained high for most vaccines between 2010 and 2021, typically in the 90s for BCG, DTP3, and Pol3, but with declines in reported denominators since 2016, which may suggest overestimation. Surveys from specific years (e.g., 2017) supported some estimates but noted recall bias. Estimates should be used cautiously due to potential data biases and lack of uncertainty measures, with detailed data available from WHO and UNICEF sources.
