Yellow fever vaccine hesitancy and its relationship with contextual, individual, or group influences and vaccine-specific issues: a scoping review

Vaccine hesitancy is a phenomenon with the potential to reduce vaccination coverage rates, as observed with the yellow fever vaccine (YFV), leading to epidemics and the reintroduc-tion of controlled immunopreventable diseases. This study, together with the scientific literature, aims to map the relationship among the lack of information, vaccine safety and adverse events, and vaccine hesitancy concerning YFV. A scop-ing review was conducted in the Virtual Health Library (VHL), National Library of Medicine (PubMed), SCOPUS, Embase, and Web of Sci-ence databases, using controlled (DeCS/MeSH) and uncontrolled descriptors. In this work, we se-lected eleven articles, published in English, Span-ish, and Portuguese, with no time limits, which met the inclusion criteria. False information, in-adequate knowledge about the immunizer, lack of time to take a vaccination, acceptance of the vaccine, vaccine safety, and fear of adverse events were related to vaccine hesitancy. This study re-inforces the importance of access to adequate in-formation, provides guidance on YFV safety and adverse events, and can aid in the development of public health strategies to mitigate hesitancy.
