Abstract

Abstract: Background: Yellow fever (YF) vaccine has the potential to cause viscerotropic and neurotropic disease in at-risk individuals. Screening patients is necessary to prevent vaccine-related life-threatening complications. We lack data on the clinical features of patients seeking YF vaccination. We aim to describe the characteristics of a cohort of patients receiving the YF vaccine before travel. Methods: A retrospective analysis of 964 patients receiving the YF vaccine (Stamaril®) from Oct 2016 to Jul 2019 was performed at the University of Colorado Hospital in the United States. 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 patients was 39 ± 18 years with a range of 9 months to 83 years. Patients who were 60 years of age and older represented 17%. Women consisted of 52%, and most of the patients were Caucasians (64%). Patients reported traveling to Africa (57%) or South America (40%). The primary destination for patients overall was 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 visiting friends and relatives were 2 times more likely to receive the YF vaccination less than 10 days before departure. Table 1.

Reasons for travel among patients receiving the YF vaccine (n=964). Conclusion: 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 travelers visiting friends and relatives. Disclosures: All Authors : No reported disclosures
