Overview

This analysis finds poor congruence in measles vaccine coverage estimates, highlighting routine and survey data discrepancies in Western Kenya.

Key Points

  • Survey-modelled estimates significantly differed in 89% of sub-counties compared to population coverage estimates.
  • Intra-class correlation coefficients showed poor concordance between survey and population/service-based coverage estimates.
  • Bias in coverage estimates was highest between survey-modelled and population-based data, reaching 18.80 percentage points.
  • Improving survey models and routine data quality is essential for reliable vaccine delivery monitoring.
