Japanese encephalitis vaccine: market and supply update

This note contains information on the global availability of Japanese encephalitis vaccines primarily affecting children in Asia and the Western Pacific and an at-risk population of nearly 3 billion people.


This note provides revised information on Japanese encephalitis vaccine market demand and supply. Several factors can affect Japanese encephalitis vaccine supply availability as the prevalence of the disease is seasonal. The timing and availability of vaccine supply could also delay programmes by up to one year if calendar schedules are mismatched with procurement lead times. Despite there being a global at-risk population of three billion in 24 countries where JE is endemic, ten countries are still pending JE vaccine introduction at national level.
