Yellow Fever Vaccine-associated Viscerotropic Disease / 대한내과학회지

ABSTRACT

This report describes a case of yellow fever vaccine-associated viscerotropic disease (YEL-AVD) that occurred after vaccination in a 23-year-old male. Seven days after vaccination, our patient presented with fever, myalgia, and nausea. The IgM enzyme-linked immunosorbent assay (ELISA) for yellow fever virus was positive. After a 24 day hospitalization, he recovered and was discharged. Yellow fever is a viral hemorrhagic febrile illness caused by a flavivirus and transmitted by mosquitoes. The clinical presentation ranges from a mild febrile illness to a serious infection, leading to hepatic and renal failure, myocardial injury, hemorrhage, and shock, with a case fatality rate of 20-30%. Because yellow fever is a potentially fatal disease, vaccination is encouraged for people traveling to high-risk areas. Although considered a safe vaccine, severe adverse reactions have been reported. In 2001, rare, but severe, acute viscerotropic disease following vaccination was first described. We report the case of a 23-year-old male with fever and hepatitis following vaccination with 17D yellow fever vaccine.
