Coronavirus Disease-2019 Vaccine Hesitancy.

Early in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, before coronavirus disease-2019 (COVID-19) vaccines were authorized, surveys began tracking public acceptance of a hypothetical COVID-19 vaccine. As vaccines became more widely available, the focus shifted from evaluating premeditative thoughts about COVID-19 vaccines to observing behaviors, measuring uptake, and characterizing factors associated with acceptance. A wealth of peer-reviewed literature examining the complexities of COVID-19 vaccine acceptance has emerged, but our understanding of COVID-19 vaccine acceptance is constantly evolving. In this article, we review the current state of knowledge regarding COVID-19 vaccine hesitancy, with an emphasis on pediatric vaccination.
