Vaccinating travelers who are at risk is necessary to prevent virus-related life-threatening complications. We lack data on the clinical features of persons seeking YF vaccination. We aim to describe the characteristics of a cohort of persons receiving the YF vaccine before travel. Methods: A retrospective analysis of 964 travelers receiving the YF vaccine (Stamaril\u00ae) from Oct 2016 to Jul 2019 was performed at the University of Colorado Hospital, U.S. Percentages, means, and standard deviations were calculated. A multivariate logistic regression model was built to evaluate the association between receiving YF vaccination less than 10 days before departure and visiting friends and relatives (VFR). Results: The average age of the subjects was 39 \u00b1 18 years with a range of nine months to 83 years. Persons who were 60 years of age and older represented 17%. Women consisted of 52%, and most of the travelers were Caucasians (64%). Travelers reported traveling to Africa (57%) or South America (40%). The primary destinations for travelers overall were Kenya (19%), Uganda (11%), and Tanzania (11%) in Africa; and Peru (14%) and Brazil (13%) in South America. The most common reasons for travel included leisure (44%), VFR (18%), and mission trips (10%). Comorbidities included a history of hematologic disorders (4%), HIV infection (2%), and diabetes mellitus (3%). The average duration between vaccine administration and travel was 43 days. Those VFR were two times more likely to receive the YF vaccination &lt;10 days before departure. Conclusions: Identifying the type of travel, itinerary, and underlying medical conditions allows providers to administer the YF vaccine to travelers safely. There is a need to identify strategies to improve the timing of YF vaccination among VFR travelers.<\/jats:p>","DOI":"10.3390\/tropicalmed5030125","type":"journal-article","created":{"date-parts":[[2020,7,29]],"date-time":"2020-07-29T07:31:45Z","timestamp":1596007905000},"page":"125","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Ensuring the Safety of Yellow Fever Vaccination in Travelers\u2014The Experience at a Large U.S. Academic Medical Center in Colorado"],"prefix":"10.3390","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5929-6219","authenticated-orcid":false,"given":"Mehdi","family":"Bandali","sequence":"first","affiliation":[{"name":"School of Medicine, University of Colorado Anschutz Medical Campus, Aurora, CO 80045, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9405-5333","authenticated-orcid":false,"given":"Jonathan","family":"Schultz","sequence":"additional","affiliation":[{"name":"Division of Infectious Diseases, Department of Medicine, University of Colorado Anschutz Medical Campus, Aurora, CO 80045, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kimlien","family":"Than","sequence":"additional","affiliation":[{"name":"School of Pharmacy, University of Colorado Anschutz Medical Campus, Aurora, CO 80045, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donna","family":"McGregor","sequence":"additional","affiliation":[{"name":"Division of Infectious Diseases, Department of Medicine, University of Colorado Anschutz Medical Campus, Aurora, CO 80045, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Solana","family":"Archuleta","sequence":"additional","affiliation":[{"name":"School of Medicine, University of Colorado Anschutz Medical Campus, Aurora, CO 80045, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sindhu","family":"Chadalawada","sequence":"additional","affiliation":[{"name":"NRI General Hospital, Pradesh 522503, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0043-7419","authenticated-orcid":false,"given":"William","family":"Mundo","sequence":"additional","affiliation":[{"name":"School of Medicine, University of Colorado Anschutz Medical Campus, Aurora, CO 80045, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4018-0195","authenticated-orcid":false,"given":"Daniel","family":"Chastain","sequence":"additional","affiliation":[{"name":"Department of Clinical and Administrative Pharmacy, University of Georgia College of Pharmacy, Albany, GA 30901, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8757-643X","authenticated-orcid":false,"given":"Carlos","family":"Franco-Paredes","sequence":"additional","affiliation":[{"name":"Division of Infectious Diseases, Department of Medicine, University of Colorado Anschutz Medical Campus, Aurora, CO 80045, USA"},{"name":"Department of Emergency Medicine, Hospital Infantil de M\u00e9xico, Federico G\u00f3mez, M\u00e9xico City 06720, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elaine","family":"Reno","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Hospital Infantil de M\u00e9xico, Federico G\u00f3mez, M\u00e9xico City 06720, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7363-8652","authenticated-orcid":false,"given":"Andr\u00e9s F.","family":"Henao-Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Division of Infectious Diseases, Department of Medicine, University of Colorado Anschutz Medical Campus, Aurora, CO 80045, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,7,29]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2013).
