WHO and UNICEF Immunization Coverage Estimates for Cook Islands (2021 Revision)

• Date: July 8, 2022, with data received as of July 7, 2022; next revision available July 15, 2023.
• Methodology: Estimates based on national government data, survey reports, and administrative records. Grade of confidence (GoC) reflects data support; categories include ••• (well-supported but risky), •• (supported by at least one datasource), and • (challenged). Extrapolation used for some years due to sparse or unreliable data. Vulnerable to biases due to varying data quality and small birth cohorts.
• Coverage Overview:
  • High coverage rates reported for most vaccines (e.g., BCG, DTP1/DTP3, Pol3, MCV1/MCV2, etc.), typically between 95% and 100% in recent years.
  • Some vaccines show no empirical data or challenges, such as DTP3 and Pol3 in 2021, or issues with numerators/denominators reported.
  • Immunization programs face potential disruptions, e.g., stockouts of vaccines like DTP-containing vaccine in 2017.
  • No survey-based estimates available for all vaccines, including RotaC and PcV3.
• Disclaimer: Estimates should be used with caution as they are based on varying quality data and lack formal uncertainty measures. Further information at: WHO Unicef Links and WHO Immunization Data.
