Analysis of WHO and UNICEF Immunization Coverage Estimates for Mongolia (2021 Revision)

Document Focus: This report presents country-specific estimates of immunization coverage for various vaccines based on data from national authorities, surveys, and other sources for the period 2010-2021. The 2021 revision indicates an unexplained 10% decrease in reported target population and doses administered between 2020 and 2021.
Methodology: Estimates are derived from reported national data, survey-based information, and administrative records. Adjustments are made for recall bias and denominator validation using UN Population Division data. The Grade of Confidence (GoC) system evaluates empirical support: ••• for high confidence, • for medium, and • for low confidence, without providing statistical uncertainty measures.
Vaccines Covered: Key vaccines include Bacillus Calmette-Guérin (BCG), Diphtheria-Tetanus-Pertussis (DTP), Polio (Pol3 and IPV1), Measles Containing (MCV1 and MCV2), Rubella Containing (RCV1), Hepatitis B, Haemophilus influenzae type b (Hib3), Rotavirus (RotaC), and Pneumococcal Conjugate (PcV3).
Grade of Confidence (GoC):
- ••• (High): Supported by reported data, survey evidence, and denominator validation.
- • (Medium): Supported by at least one data source but challenged by potential inconsistencies.
- • (Low): Lacks sufficient sources or data challenges actual levels.
- Estimates reflect potential underreporting and data biases, with notes suggesting actual coverage may be lower than reported.
Limitations and Cautions: Data quality varies, and estimates should be used carefully for decision-making. Annual updates are provided, with the next revision expected in July 2023. Sources include national surveys and program reports, but findings are not guarantees.
