The disease is preventable with a live-attenuated vaccine, which is considered safe, effective, and provides lifelong immunity. Since 2016, Brazil has experienced an influx of Yellow fever outbreaks throughout the country due to the expansion of the virus. This literature review examines factors contributing to the expansion of Yellow fever throughout Brazil and identifies challenges to Yellow fever prevention and control efforts ongoing throughout the country. A systematic literature search was conducted, and twenty-nine relevant articles were found to meet the selection criteria of Yellow fever, Brazil, challenges, and population health. This review of literature revealed lack of Yellow fever immunity, adverse effects of vaccination, deforestation, fractional dosing, and various vaccine supply chain challenges to be the leading challenges facing the Yellow fever control efforts in Brazil since 2016. In the interest of public health, these findings are significant because they have shown that initiating additional prevention methods and revising policies in turn could exceedingly end the Yellow fever epidemic in Brazil, while simultaneously reducing morbidity and mortality of this vaccine-preventable disease.} }
