Yellow Fever (YF) immunization required a single dose vaccine with boosters every 10 years. After International Health Regulation (IHR) amendment annex 7 (July 2016), it was accepted that a single dose confers lifelong immunity. Since pre-travel advice is as important as vaccination when traveling, it is essential to clarify why travelers come to a travel health consultation, with the possibility of IHR amendment having a negative impact on travelers' health. This study aims to describe travelers' reasons to come to a pre-travel consultation in Lisbon and if they would return if they wouldn't need the YF vaccine booster.
An observational cross-sectional study was conducted during 5 months in the waiting room of Instituto de Higiene e Medicina Tropical travel clinic in Lisbon, Portugal. Travelers were asked about sociodemographic characteristics, destination country, travel duration and reasons to travel in an anonymous self-administered questionnaire.
A total of 1043 travelers agreed to participate in the study. Although 61.0% (627/1028) did not come to the clinic to get the YF vaccine, from those who did, 36.7% (133/362) would not come and 12.9% (47/362) didn't knew if they would come if the vaccine would not be necessary.
The IHR amendment may have a negative impact on travel clinic attendance and on travelers´ health.
黄热病（YF）免疫接种需要接种一剂疫苗，每10年加强一次。《国际卫生条例》（IHR）修订案附件7（2016年7月）发布后，人们认为单剂量疫苗可提供终身免疫。由于旅行前的建议与旅行时的疫苗接种同样重要，因此有必要弄清楚旅行者前来进行旅行健康咨询的原因，因为IHR修订案可能会对旅行者的健康产生负面影响。本研究旨在描述旅行者前往里斯本进行旅行前咨询的原因，以及如果他们不需要黄热病疫苗加强针，是否还会再来咨询。
在葡萄牙里斯本热带卫生与医学研究所旅行诊所的候诊室进行了为期5个月的观察性横断面研究。通过一份匿名的自填问卷，询问旅行者的社会人口学特征、目的地国家、旅行时长和旅行原因。
共有1043名旅行者同意参与该研究。尽管61.0%（627/1028）的人不是为了接种黄热病疫苗而来诊所，但在那些因接种疫苗而来的人中，36.7%（133/362）表示如果不需要疫苗就不会再来，12.9%（47/362）表示不知道如果不需要疫苗是否还会再来。
IHR修订案可能会对旅行诊所的就诊率和旅行者的健康产生负面影响。
