Methodology and Definitions:

WHO & UNICEF provide country-specific, empirical data-based estimates of immunization coverage by vaccine to surrogate markers.
Common vaccines tracked include BCG, DTP1/DTP3, HepBB/HepB3, MCV1/MCV2, Pol3, IPV1, Hib3, RCV1, RotaC, and PcV3.
Estimates use survey data, administrative reports from national programs, empirical assessments, recalculated data, and assume coverage consistency over years when data is missing.
Grade of Confidence (GoC) indicates the level of empirical support: Level 2 means support from one source; Level 1 is challenged; "No accepted empirical data" is a specific case category.
Confidence level is not provided via intervals or probability models; estimates should be used cautiously.

Key Findings:

BCG: Coverage declined from ~86-88% in 2014-2016 to ~20% in 2022. GoC is Level 2 for all years.
DTP1/DTP3/ Pol3/IPV1/IPV2/DTP/D: Coverage generally remains high (>93% for DTP3 in 2022). GoC is mostly Level 2 or "No accepted empirical data."
MCV1/MCV2/RMV1/RCV1: Coverage shows high and stable values (often 91-93%). GoC is Level 2, except for a pre-coverage period (GoC Level 1) and times with missing data (GoC "No accepted").
HepB/HepBB/HepB3/PcV3/Hib3/RotaC: Coverage is frequently high (>90%), with GoC largely Level 2. For HepB3, coverage is included, but HepBB is not estimated due to national policy.
COVID Impact: 2020 saw a significant drop in certain vaccinations due to COVID-19 disruptions, especially in Q2.

Conclusion & Caveats:

High coverage levels are reported for most vaccines over the review period.
Data sources vary, and adjustment methods are used where direct data is limited.
GoC indicates risk of inaccuracy or unreliability for many estimates due to lack of independent confirmatory data.
Further information is available via official WHO and UNICEF data portals.
