Abstract

Yellow fever vaccine is used since the 1930’s to prevent yellow fever a severe infectious disease caused by yellow fever virus (YFV) mainly transmitted by Culicidae mosquitoes of the genera Aedes and Haemagogus. Until 2013, the World Health Organization (WHO) recommended a vaccine dose each ten years. This was changed and a new recommendation of a single shot for life protection against YFV infection was established. Recent evidences published elsewhere suggest that at least a second dose is needed to fully protection against yellow fever disease. In this work we discuss the feasibility of one or two doses, the necessity of a new and modern vaccine and ask for a WHO meeting to a new recommendation on YFV vaccination for people living in or travelling to the endemic areas.
