Summary of WHO and UNICEF Immunization Coverage Estimates for Lao People’s Democratic Republic (Lao PDR) - 2021 Revision

WHO and UNICEF provide country-specific immunization coverage estimates for Lao PDR, updated as of July 2022. For the 2021 revision, estimates rely on reported data, survey results (e.g., MICS surveys, National Immunization Surveys), and administrative records, with no pooling from other countries. Key aspects include:

Methodology: Estimates are based on empirical data, calibrated to previous years (e.g., 2016 levels for many vaccines) to account for data consistency issues. A Grade of Confidence (GoC) is assigned, reflecting the strength of data support but not data quality judgments. For instance, GoC "•••" indicates strong support from multiple sources, while "•" suggests limited support and caution is needed.
2021 Estimates: The 2021 figures are largely calibrated from 2016 due to reliance on a planned but not yet completed Multiple Indicator Cluster Survey (MICS) in 2022. Common challenges include routine reports of vaccine stock-outs at national or subnational levels, data inconsistencies in surveys (e.g., LSIS II 2017 results often questioned), and calibration based on earlier years like 2016. Example estimates for key vaccines in 2021:
- BCG: 80% (GoC indicates support, but stock-outs noted).
- DTP1: 77% (calibrated to 2016, with survey modifications).
- Pol3: 84% (adjusted from DTP3 with campaign influences considered).
  For other vaccines like HepBB, HepB3, and Hib3, estimates are similar, often with low confidence due to data biases and recall issues.
General Notes: Immunization coverage for most vaccines is high, but data gaps and potential misreporting reduce reliability. HepB birth dose coverage started in 2017 with preliminary estimates. Overall, estimates should be used cautiously, as data quality varies, and the next revision is due in July 2023.
