WHO and UNICEF provide estimates of immunization coverage in Colombia based on national government data, spanning the period 2010 to 2021, with the 2021 revision reflecting July 2022 data. Coverage is assessed for various vaccines including BCG, DTP, polio, measles, hepatitis B, and others, primarily relying on administrative reports and empirical data, often without high-quality nationwide surveys. The Grade of Confidence (GoC) is assigned to each estimate, indicating the level of support: GoC=R+ D+ (well-supported by reported data and surveys), with R- or D- noting challenges. Key findings show generally high coverage for vaccines like BCG and some DTP doses, but trends are influenced by inaccurate target populations or denominators. For instance, HepB birth dose coverage improved with better reporting, while other vaccines showed fluctuations.

• Methodology: Estimates are not adjusted from other countries and are subject to biases; all should be used with caution due to potential data issues.

• Notable Challenges: Colombia faces difficulties in ensuring accurate immunization registry counts, leading to periods with estimated coverage changes due to relative decreases in target population data.

The reports are available for further review.
