Background

WHO and UNICEF provide country-specific estimates of immunization coverage for Suriname based on data from surveys, administrative reports, and program data. Their methodology includes calibrating data, considering the grade of confidence (GoC), and noting challenges in data quality.

Key Estimates and Trends

• Vaccines Covered: Includes BCG, DTP1/DTP3, Pol3, IPV1, MCV1, MCV2, RCV1, HepBB, HepB3, Hib3, RotaC, PcV3, and YFV.
• Annual Coverage (2010-2021):
  • Most vaccines show fluctuations due to factors like COVID-19 disruptions and stockouts.
  • For example:
    • BCG: Coverage stable but anchored around 90-80%.
    • DTP1/DTP3 and Pol3: Suggest recovery from COVID-19 and previous deficits, with GoC varying from • to •••.
    • General trend: Coverage declined during disruptions (e.g., 2016-2020), with calibration to earlier years often noted.
• Grade of Confidence (GoC):
  • Indicated by three symbols (• to •••), with ••• being the highest support.
  • Many estimates (especially post-2020) challenged due to COVID-19, survey trends, and data inconsistencies.
• Methodology: Estimates not borrowed from other countries; survey evidence and administrative data integrated where available. Some doses calibrated to 2016 levels.

Challenges and Considerations

• COVID-19 Impact: Significant decline in coverage in 2020-2021, attributed to service disruptions.
• Stockouts: Frequent underreporting or anticipated issues (e.g., syringe shortages) affecting several vaccines.
• Data Quality: Figures based on reliable but varying sources; disclaimers advise cautious use due to potential inaccuracies.

Context

These estimates help track Suriname's immunization performance; however, high-level empirical assessments recommended for validation. Next revision due July 15, 2023.
