Objectives:
Measles is a highly contagious airborne disease capable of rapid transmission in healthcare and school settings when immunity gaps accumulate. This review aims to examine the evolution of the measles immunization program in the Republic of Korea (ROK) and analyzes policy implications through international comparison.
Methods:
This narrative review uses the Korea Disease Control and Prevention Agency guidelines, national statistics, 2018-2019 outbreak reports, World Health Organization and United Nations Children's Fund coverage estimates, and official guidelines and reports from the United States, the United Kingdom, Japan, and Canada. The comparison is based on four criteria: the two-dose schedule, coverage, school-entry verification, and outbreak response.
Results:
ROK strengthened measles control through routine measles-mumps-rubella vaccination, the measles-rubella catch-up campaign in 2001, and a mandatory school-entry verification system. The 2018-2019 import-related outbreaks were contained through rapid reporting, laboratory confirmation, contact management, and targeted vaccination. From 2015 to 2024, first-dose coverage remained at 97.3-97.9% and second-dose coverage ranged from 94.6-97.8%. International comparison showed that the ROK maintained a high two-dose coverage and a stable school-entry verification system, while regional immunity gaps persisted in some countries.
Conclusions:
High two-dose coverage and school-entry verification have resulted in the elimination of measles in the ROK. Continued management of susceptible populations and policy evaluation using internationally comparable indicators remain important.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
