Summary of WHO and UNICEF Immunization Coverage Estimates for Botswana (2021 Revision)

• Report Period: Estimates cover data up to 2021, with calibration to 2012 levels for many indicators.
• Indicators Covered: Key vaccines include BCG, DTP1, DTP3, Pol3, IPV1, MCV1/2, RCV1, HepBB, HepB3, Hib3, RotaC, and PcV3.
• Coverage Trends: Most indicators show coverage above 90% in recent years (e.g., BCG, DTP1, Pol3, DTP3 consistently >95%), but with variations due to administrative issues and data calibration; some years have exclusions due to poor quality or fluctuations.
• Data Quality Issues: Common problems include inconsistent reporting, stock-outs (e.g., Polio and other vaccines), over-reporting exceeding 100%, and reliance on older survey data; no nationally representative surveys in recent years.
• Grade of Confidence: Assigned based on available data; estimates are often challenged (e.g., D-R-, R-) due to data reliability; GoC maintained for consistency across vaccines where no better data exist.
• Recommendations: WHO and UNICEF advise high-quality household surveys, administrative system assessments, and continued monitoring to improve coverage accuracy.
• Disclaimer: All estimates should be used with caution, as data quality varies, and no probability models provide uncertainty intervals.
