IVI’s 25th International Vaccinology Course
31 August – 4 September 2026
Seoul, Republic of Korea | Kigali, Rwanda | Stockholm, Sweden
The 25th International Vaccinology Course took place from 31 August to 4 September 2026 across Seoul, Kigali, and Stockholm, marking the 25th anniversary of the International Vaccine Institute’s flagship vaccinology training program. Under the theme “Vaccines for a Connected World: A One Health Perspective,” the course explored the increasingly interconnected nature of global health and the importance of collaboration across disciplines, sectors, and borders. The course explored how vaccines support the broader One Health framework, which recognizes the close connection between human, animal, and environmental health. The course further examined how integrated approaches spanning vaccination, surveillance, research, innovation, and policy can strengthen preparedness, advance global health security, and support more effective responses to health challenges.
About the IVI International Vaccinology Course
IVI’s International Vaccinology Course is a training program to build knowledge, practical skills, and connections in vaccine science and development. Through lectures, quizzes, case studies, networking opportunities, and site visits, the course provides vaccine professionals with an inclusive and immersive training experience. World-renowned experts from diverse fields, including vaccinology, immunology, epidemiology, communication, and related fields, serve as faculty members.
Established in 2000, the International Vaccinology Course is held annually at IVI’s headquarters in Seoul, Republic of Korea and has since expanded to additional sites in Stockholm, Sweden and Kigali, Rwanda, where IVI’s Europe Regional Office and Africa Regional Office are located. It is a vital component of IVI’s work to discover, develop, and deliver safe, effective, and affordable vaccines—empowering vaccine equity, impact, and sustainability globally. The program has trained more than 5,200 vaccine professionals from across the world in person and certified an additional 1,100 participants through an online edition of the course, fostering lasting collaborative partnerships in research and public health.
