This study aimed to establish a foundation for future collaborations aimed at preparing for and responding to infectious diseases by examining the vaccine injury compensation programs (VICPs) of East Asian countries. We reviewed the current status of VICPs in the Republic of Korea, Japan, and Taiwan by searching national government websites and reviewing relevant literature. Additionally, we conducted email inquiries targeting experts from Japan and Taiwan.Through the comprehensive analysis of VICPs in these 3 countries covered various aspects,we identified several similarities and differences in the VICPs across these countries. Whilethe governments of the Republic of Korea, Japan, and Taiwan play a central role in supporting investigations into vaccine injuries and managing compensation procedures based on legalstatutes, they differ in terms of financial resources for compensation, the range of vaccinescovered, and the criteria for assessing causality. In the Republic of Korea, Japan, and Taiwan,compensation is typically paid in a lump sum, although the specific benefits available vary bycountry. This study on VICPs in the Republic of Korea, Japan, and Taiwan provides valuable insights for the further development and management of domestic systems.

Purpose: The purpose of this study is to develop the Theory of Uncertainty on COVID-19 using the strategy of theory derivation. Methods: Theory derivation was carried out in the following steps: review the literature to explore the phenomena related to uncertainty on COVID-19; select a parent theory that provides valuable concepts and a useful structure for derivation, and identify the concepts and structure of the parent theory to use in derivation; modify and redefine the concepts and structure of the parent theory to create a derived theory. In the literature review process, relevant findings were synthesized to support the propositions of the derived theory. Results: The Theory of Uncertainty on COVID-19 was derived from the Uncertainty in Illness Theory to make it relevant and applicable to a specific aspect of uncertainty on COVID-19, health-related uncertainty perceived by a person who has not contracted COVID-19. It is a middle-range theory targeting the general population and consists of a linear and unidirectional model centered on three themes: antecedents of uncertainty, appraisal of uncertainty, and coping with uncertainty. Conclusion The Theory of Uncertainty on COVID-19 will be able to contribute to efforts to manage perceived uncertainty on pandemic diseases and improve individual biopsychosocial health in the future.
