Immunization Coverage Estimates for the Republic of Korea (2021 Revision)

Background

WHO and UNICEF estimate national immunization coverage using empirical data, surveys, grey literature, and expert consultation. Doses are analyzed for reliability, and estimates reflect coverage levels for young children.

Key Methodology

• Estimates rely on national or surveyed data, analyzed without statistical uncertainty ranges.
• Coverage grades (GoC) indicate empirical support, from challenged to strongly supported.

Republic of Korea Performance

High coverage overall, except recent years with missing data (estimated through extrapolation).

• BCG, DTP3, Pol3 (polio):
  • 2021: Extrapolation based on national data (No accepted empirical data)
  • 2020: Same
  • 2019-2014: Coverage approx. 98-99%, supported by data.

Important Notes

Estimates may be affected by data irregularities or missing years, with cautious use recommended due to limited data verification.
