Purpose : Yellow fever, a mosquito-borne viral hemorrhagic fever, is one of the most lethal diseases. Recently there have been an increasing number of Korean children who have travelled to yellow fever endemic zones and were administered yellow fever vaccine (YFV). Therefore, we carried out this study to provide child travelers with safety information of YFV. Methods : This study was conducted at the International Clinic of National Medical Center in Seoul between April 2007 and June 2008 for the evaluation of adverse events of YFV. One hundred twenty-five children received YFV (17-DD) and were prospectively monitored for adverse events through telephone interviews on day 3, 6, 9, 16, 23 and 30 after vaccination. Results : Adverse events were observed in 31 (24.8%) of 125 child travelers who received the YFV. The mean age was 12.5${\pm}$5.0 years. Sixty-six of the child travelers (52.8%) were males. The common adverse events were pain in 11 (8.8%), swelling in 8 (6.4%) and redness in 7 children (5.6%) at the injection site. The systemic adverse events included mild fever in 5 (4.0%), headache in 5 (4.0%), cough in 4 (3.2%), abdominal pain in 3 (2.4%), and vomiting in 2 children (1.6%). Most of the adverse events were detected within 7 days of administration and there were no differences in adverse events by gender or age. All travelers who had complained of symptoms improved spontaneously or following symptomatic treatment. Conclusion : This study showed that YFV is well-tolerated and there were no reports of severe adverse events. Studies are ongoing to clarify the cause and risk factors for rare adverse events.

플라비바이러스(Flavivirus)는 모기와 같은 곤충을 매개로 하여 인체에 감염된다고 잘 알려져 있다. 그 대표적인 예로 지카 바이러스(Zika virus), 뎅기 바이러스(Dengue virus), 황열 바이러스(Yellow fever virus), 일본 뇌염 바이러스(Japanese encephalitis virus) 등을 들 수 있다. 본 연구에서는 생물정보학을 기반으로 인체 감염 주요 플라비바이러스인 지카 바이러스, 뎅기 바이러스. 황열 바이러스, 일본 뇌염 바이러스의 총 4종류 플라비바이러스에 공통적으로 적용 가능한 펩타이드 백신 후보를 제시하고자 한다. 먼저 UniProt (The Universal Protein Resource)의 유전자 서열정보를 이용하여 4종류의 바이러스가 가진 단백질 중 백신으로써 적합한 단백질을 선정하였다. 선정된 단백질의 아미노산 서열정보를 바탕으로 IEDB (Immune Epitope Database And Analysis Resource)를 활용한 에피토프(epitope) 분석을 통해 에피토프로 작용하는 4 종류 바이러스의 공통적인 서열을 도출하였다.
