This article examines disaster-related research ethics in terms of its values, principles, systems of review, and methodologies. The article also reviews some of the major ethical issues in, and current status of, research ethics related to COVID-19 in Korea. Principles to be considered in disaster-related research include scientific validity, social value, risk-to-benefit ratio, time-sensitive reviews, and informed consent. It is necessary to develop guidelines for disaster-related research ethics that facilitate complete, yet time-sensitive ethical reviews. The potential benefits, scientific validity, and social value of research plans should be harmonized, and the participation of research subjects should be based on scientific evidence. A comprehensive review and plan for national-level research and research ethics governance appropriate to disasters is needed in Korea.
