Immunization Coverage Estimates for Cuba (WHO and UNICEF 2021 Revision)

Overview

This report details WHO and UNICEF's joint estimates of national immunization coverage in Cuba for the 2021 revision, based on data received up to July 7, 2022. The estimates focus on key vaccines and are reviewed annually, with the next revision available in July 2023. Coverage levels are consistently high across most indicators, though some years show minor adjustments due to data quality issues.

Vaccines Covered

• Key Vaccines: BCG (tuberculosis), DTP1/DTP3 (diphtheria, tetanus, pertussis), Pol3 (polio), IPV1 (inactivated polio), MCV1/2 (measles-containing), RCV1 (rubella-containing), HepBB/HepB3 (hepatitis B), Hib3 (Haemophilus influenzae type b), and others as listed in the background.
• Indicators: Include routine doses, birth doses, and booster shots for infants and children, categorized by vaccine type and age group.

Data Sources and Methodology

• Sources: Estimates are based on national government reports, survey data (e.g., Cuba Multiple Indicator Cluster Surveys), and administrative data.
• Grade of Confidence (GoC): Indicates the strength of empirical support; reflects data quality without subjective uncertainty assessments; estimates may be challenged or well-supported based on sources like reported data, surveys, or denominators.
• Method: Involves interpolation, recalculation with independent denominators, and validation from surveys. Coverage is assessed for specific doses and age cohorts, with some doses estimated from others (e.g., Pol3 from three doses of polio vaccine).

Estimated Coverage Trends

• High coverage rates are maintained across most vaccines, with estimates typically ranging from 96% to 100% for years 2010-2021, sometimes interpolated or adjusted based on available data or surveys.
• Variations noted in some cases, such as influenza vaccine and Pol3, due to inconsistent survey results or data challenges. Generally, Cuba shows strong immunization performance, but estimates are used with caution due to potential biases in data sources.

Disclaimer

• All estimates are based on varying data quality and should be assessed carefully for the intended use, as there are no classical uncertainty measures like confidence intervals provided.
