WHO and UNICEF Estimates of Immunization Coverage for Jamaica: 2022 Revision

• Report Date: July 16, 2023 (Estimates based on data as of June 26, 2023). Next revision due July 15, 2024.
• Estimates Available: Coverage for key vaccines (BCG, DTP1, DTP3, Pol3, MCV1, MCV2, RCV1, IPV1, HepB3, Hib3, Pol3) from 2011 to 2022.
• Coverage Trends: Immunization coverage in Jamaica generally fluctuates annually, influenced by reported vaccination administration, survey data, and historical records. Key challenges include:
  • Stockouts: Regular reports of national or subnational stock-outs for vaccines (e.g., Polio, DTP, Hepatitis B) or supplies like AD syringeshave impacted coverage. Stockouts were frequently cited for years 2019-2022.
  • Confidence in Estimates (Grade of Confidence - GoC): Estimates are assigned a GoC level ('•••', '••', or '•') based on the data sources used (Routine [R], Administrative [D], Survey [S]). A higher GoC ('•••') indicates more robust support from reported and/or survey data, although the estimate remains subject to potential error. Declines or increases were often attributed to vaccine shortages or changes in scheduling/recommended age.
  • Data Reliability: Data quality varies. National official (GoC) and administrative (Admin) figures sometimes differ and may reflect reporting issues or different assumptions (e.g., polio coverage 2013, Hepatitis B birth dose). Survey data (GoC) for certain vaccines (like DTP2) directly informs specific estimates. The absence of survey data (e.g., for Rotavirus, Pneumococcal) relies on reported data.
• 2022 Data: The 2022 coverage estimates were largely informed by reported data or assumptions based on prior years. For some vaccines (BCG, DTP1, MCV1), a 2022 Multiple Indicator Cluster Survey was known but final results awaited. Annual reports often flagged four to six-month vaccine stockouts impacting that year's coverage.
• Disclaimer: All estimates should be used cautiously, considering the data limitations and the GoC assigned by WHO/UNICEF. There are no recommended uncertainty ranges (e.g., confidence intervals). The GoC reflects empirical support, not judgments on data quality.
• Surveys: The document includes survey results from various years (e.g., 2009, 2011, 2004, 2005, 2006, 2008) which factor into specific years' estimates or supplementation. Further data and estimates can be found online.
