Estonia 2022 Immunization Coverage Summary

Coverage Estimates

WHO and UNICEF provide these estimates based on:

Estimation Sources

Acquired data is curated from different sources:

• Administrative: National reports from health providers.
• Survey: Population-based household surveys (where available).
• Official: National assessments of coverage.
• Independent Denominators: Recalculated with UN Population Prospects data.

Key Immunization Coverage

Overview by Vaccine:

¹ Based on administrative data, subject to independent denominator and surveys:

Grade of Confidence (GoC)

GoC indicates the strength of evidence behind the estimate:

• •• Well supported, with high confidence.
• • Limited data sources; carries some risk.
• No support or challenge: When no data sources align, or sources challenge the estimation.

Key Observations

- Data Trends:

• Immunization decline noticed during 2022-2023.
  • Examples:
  • BCG coverage dropped from 90% to 78%.
  • DTP1 fell from 91% to 86%.
  • Pol3 decreased from 91% to 89%.

- Confirmed Discrepancies:

• The official administration and estimated adjustment sometimes challenge each other; data recalibration is recommended for reliability.

- Technical Notes:

• All data are subject to uncertain biases and interpolation when surveys are missing.
• Estimates use available numerator/denominator data, but some ambiguities remain (e.g., vaccine type, schedules).

Authorities & Transparency

• WHO and UNICEF provide estimates freely but note no warranty or liability.
• Both organizations advise caution on interpretation.
