Yellow fever and Japanese encephalitis vaccines: indications and complications.

摘要

Appropriate administration of yellow fever or Japanese encephalitis vaccines to travelers requires an assessment of the traveler's risk for infection with these vector-borne flaviviruses during their travels and the presence of risk factors for adverse events following immunization. Japanese encephalitis and yellow fever vaccines have been more frequently associated with serious adverse events following immunization since the early 1980s and the late 1990s, respectively. This article describes the adverse events, the magnitude of their risk, and associated risk factors.
