professional reports from WHO and UNICEF documented Belarus's immunization coverage rates for key vaccines between 2010 and 2021. For vaccines like BCG, HepBB, and various doses of DTP, Pol, MCV, and HepB, coverage consistently remained above 97% across most years analyzed, with many years seeing values of 98% or 99%.

Coverage data was primarily based on national government reports from health services, adjusted by an independent denominator (from UN Population Division data). Generally, the Grade of Confidence (GoC) level reflected as •• or ••• (medium to high confidence) for most years, particularly from 2010 onwards, though some earlier years had lower confidence.

A notable finding was the absence of nationally representative household surveys for immunization within the last five years by 2022, and key surveys like the Multiple Indicator Cluster Survey (MICS) were only conducted in 2004. Since 2016, reported target populations for vaccines in the first year of life declined by 33%, a factor accounted for in the estimates. Estimates were challenged due to data limitations, including potential inaccuracies in administrative data and lack of recent surveys.

These estimates help assess Belarus's performance in maintaining near-universal immunization coverage for key vaccines and disease elimination goals, highlighting both strengths and data-related weaknesses.
