“…Interestingly, four of the studies evaluated vaccine performance in the context of mass vaccination campaigns 25,26,29,32 The seroconversion rates in these studies ranged from 89.7% to 98.2%. Moreover, Tavares-Neto and others 29 reported a seroconversion rate of 94% (363 of 387) after a vaccination campaign in a remote region of Brazil, which was characterized by its difficult access, minimally trained personnel, and limited resources.…”

Abstract. Current regulations stipulate a yellow fever (YF) booster every 10 years. We conducted a systematic review of the protective efficacy and duration of immunity of YF vaccine in residents of disease-endemic areas and in travelers to assess the need for a booster in these two settings and in selected populations (human immunodeficiency virus-infected persons, infants, children, pregnant women, and severely malnourished persons). Thirty-six studies and 22 reports were included. We identified 12 studies of immunogenicity, 8 of duration of immunity, 8 of vaccine response in infants and children, 7 of human-immunodeficiency virus-infected persons, 2 of pregnant women, and 1 of severely malnourished children. Based on currently available data, a single dose of YF vaccine is highly immunogenic and confers sustained life-long protective immunity against YF. Therefore, a booster dose of YF vaccine is not needed. Special considerations for selected populations are detailed.
