Narrative review of South Korea's legislative response to COVID-19 and MERS

This narrative review systematically analyzes the longitudinal evolution of South Korea’s legal and institutional frameworks from the 2015 MERS outbreak through the COVID-19 pandemic. The study introduces the “Pandemic Response Pentad,” an original conceptual model positioning Legislation as the foundational core, mediated by Governance, to drive three interconnected field operations. Based on this framework, Korea’s infectious disease control system is evaluated across four operational domains: (1) governance reform and personnel structure enhancement, (2) epidemiological response capabilities and data utilization, (3) medical response system, including vaccination programs and supply stockpiling, and (4) social response mechanisms, encompassing social distancing and the protection of vulnerable populations. While rapid legislative enactments enabled effective disease control, they also generated profound ethical tensions regarding fundamental human rights. To mitigate these unintended socioeconomic consequences, Korea institutionalized extensive statutory compensation mechanisms for healthcare facilities, small business owners, and vaccine injuries. The findings highlight that advancing national research infrastructure and establishing policy-oriented think tanks for future pandemic preparedness strictly require proactive legislative backing. Ultimately, this study provides valuable insights into the critical interplay between legal mandates and institutional resilience in global health crisis management.
