以下是针对Chile的WHO和UNICEF免疫覆盖率估计报告的总结内容，基于2021年修订版，发布日期为2022年7月8日。报告涵盖了多种疫苗的覆盖率数据从2010年至2021年。

• Report title: WHO and UNICEF estimates of immunization coverage for Chile, 2021 revision.
• Background: WHO and UNICEF jointly estimate national immunization coverage based on data from member states, including administrative reports, surveys, and empirical data, with careful consideration of potential biases. The estimate methodology began in 2015.
• Key vaccines covered: BCG, DTP1, DTP3, Pol3, IPV1, MCV1, MCV2, RCV1, HepBB, HepB3, Hib3, RotaC, PcV3.
• Data sources: Rely on nationally reported data, interpolated surveys, and recalculated denominators, but quality varies. Coverage estimates use a grade of confidence (GoC) system to indicate support level, without providing classical uncertainty measures.
• Trends and findings: For example, BCG coverage has been around 95-98% since 2010; DTP3 coverage fluctuates, with declines potentially linked to school vaccination disruptions; HepBB coverage was 65% in 2019 but improved. Data often lack independent verification.
• Limitations: Estimates are based on varying data quality; no probability models are used. Users are advised to assess the context and objectives when interpreting the data, as bias and errors are possible.
• Next revision: Expected in July 2023.
