Yellow fever is a mosquito-transmitted hemorrhagic viral disease that is endemic 
to tropical regions in South America and Africa. It remains a significant health 
concern for deploying military personnel, accordingly vaccination is frequently 
performed on troops. Although the vaccine is generally administered with only 
minor complications, rare severe complications are also reported. Herein, we 
report a mild case of yellow fever vaccine-associated viscerotropic disease 4 
days after administration of the vaccine. The various complications of the 
vaccine and their pathogenesis are also reviewed.
