Background: This study was performed to determine the priority of vaccine introduction for five vaccine-preventable diseases (VPDs) caused by Haemophilus influenzae type b (Hib), pneumococcus (Spn), hepatitis A virus (HepA), rotavirus (RV), and human papillomavirus (HPV) to the future Korean National Immunization Program (NIP) and to suggest framework programs to assist decision makers on implementation of the NIP. Methods: Following analysis of the disease burden and economics of the five VPDs by the core team and Korean Advisory Committee on Immunization Practices sub-committee members, a Delphi survey was administered to 94 Korean experts using structured questionnaires that provided the reference data. The two evaluation frameworks for NIP prioritization were (1) a disease-related framework and (2) a vaccine-related framework. After analyzing the responses, a meeting of experts was held to build a consensus for determining how to prioritize NIP implementation. Results: The average scores for relative importance were 63.29 for the disease-related framework and 36.71 for the vaccine-related framework. Within the disease-related framework, the mortality and case fatality rate was the highest scored factor (8.97), whereas within the vaccine-related framework, efficacy of the vaccine was considered the most important factor (9.56). On average, Spn, Hib, and HepA had the highest priority scores. Conclusion: The Korean experts suggested that the main factors influencing the decision to adopt new vaccines in the Korean NIP should be disease mortality, case fatality, and the efficacy and effectiveness of the vaccine. Among the five selected VPDs, Spn, Hib, and HepA were considered to be of higher priority than RV and HPV.
