Parental vaccine hesitancy has been a hotly debated issue long before the COVID-19 pandemic. Still, the emergence of a new vaccine during this public health crisis made even pro-vaccine individuals reconsider vaccines for their children. This scoping review was conducted to understand why parents expressed hesitancy towards the COVID-19 vaccine for children under 12 years old. The search included primary sources of evidence published in English from 2020-2022. A final 41 articles met the criteria. Overall, more vaccine-hesitant characteristics were non-white, female, lower education level, lower income, on public insurance, conservative political affiliation, younger age, and rural residence. Concerns affecting confidence in the vaccine were the risk of possible side effects and lack of trust in the development of the emergency approval of the vaccine. School nurses can acknowledge parental fears and provide parents with evidence-based information when communicating with them about vaccinations.
