Vaccination is a cornerstone of public health, preventing infectious diseases with significant contribution to human health. In South Korea, the Korea Expert Committee on Immunization Practices (KECIP) plays a pivotal role in guiding national vaccination policies. In this comprehensive review, we investigated the history, legal basis, operation, and achievements of the KECIP, highlighting its critical role in shaping the country's successful vaccination program. We analyze the KECIP's diverse responsibilities, including deliberating on national immunization programs, establishing vaccination criteria, managing targeted infectious diseases, and formulating eradication strategies. Also, we revealed its well-defined structure, specialized subcommittees, and ethical protocols that ensure transparency and integrity. Furthermore, we explored the KECIP's strategic evolution, showcasing its contributions to expanding vaccine coverage, implementing emergency approvals, and optimizing foundational vaccinations for all age groups as well as special populations including immunocompromised individuals. By combining scientific rigor, expert insights, and a commitment to public health, the KECIP had navigated the dynamic landscape of infectious disease control, contributing significantly to South Korea's impressive vaccination achievements.
