报告摘要

Revision Date: July 1, 2023; Data cutoff: June 26, 2023; Next revision: July 15, 2024.
Methodology: Estimates based on national reports, surveys, administrative data, and interpolation. The Grade of Confidence (GoC) reflects empirical support without judgment on data quality. For example, 2013 coverage estimation used reported data and survey evidence.
Key Vaccines Covered: BCG, DTP, Polio, Measles, Hepatitis B, Hib, Pneumococcal, Rotavirus, etc.
Estimates Overview: Coverage generally stable and high (e.g., >90% in most years), but varies by vaccine and year. Notable events included a 2017 IPV stockout reducing coverage to 46%. Recent coverage for HepB birth dose began in 2018, with data improving over time. Pol3 and MCV1 frequently exceeded 95%.
Grades of Confidence (GoC): Most GoCs indicate at least moderate empirical support (e.g., R+ or S+), but some estimates are challenged due to data gaps or business process issues, requiring cautious use.
Limitations: Data quality is variable, and estimates rely on interpolation or extrapolation, so reliability depends on GoC but underscores the need for careful interpretation.
Trends: Immunization coverage has remained robust for many vaccines, with fluctuations explaining temporary dips. Introduction of new vaccines (like Rotavirus and HepB) may provide additional insights into coverage gaps.
