Acute viscerotropic disease following vaccination against yellow fever

Acute viscerotropic disease following yellow fever vaccination (YEL-AVD) is a rare but serious complication of vaccination with 17D yellow fever vaccine. This paper reviews the existing literature regarding YEL-AVD and discusses possible etiologic mechanisms. A greater understanding of this condition is essential to assuring safe and effective prevention of yellow fever and vaccination against other arboviral diseases for which 17D-based vaccines are being developed.
