Summary of WHO and UNICEF Immunization Coverage Estimates for Democratic People’s Republic of Korea (DPRK), 2021 Revision

Based on data received as of July 7, 2022, WHO and UNICEF estimate immunization coverage for various vaccines in the DPRK. Key points include:

• Coverage Levels: Estimates range from 0% to 100%, with most vaccines maintaining high coverage (typically 90-100%) from 2010-2021 for vaccines like BCG, DTP3, Pol3, and HepBB. Notable drops occurred during vaccine stock-outs, such as 41-42% for PCV3 in 2021 and 0% for IPV1 in 2016.
• Methodology: Estimates rely on reported data, surveys, and administrative sources. A grade of confidence (GoC) system indicates support from data types, ranging from high confidence (e.g., survey-calibrated data) to challenged estimates due to data limitations.
• Vaccine-Specific Notes:
  • BCG, DTP, Pol3, HepBB, HepB3 show sustained coverage above 90% in most years.
  • IPV1 and OPV/Pol3 were affected by stock-outs, leading to lower estimates (e.g., 52% in 2016 and 0% in some cases).
  • MCV2 and Hib3 show high coverage but with some data gaps or low confidence in estimates.
• Overall Trends: Coverage fluctuates based on reporting and supply issues; surveys from 2015-2017 provided robust data during disruptions, but estimates should be used cautiously.
• Next Revision: Available on July 15, 2023, for updated immunization coverage data.
