Despite substantial health benefits and prolific research efforts to demonstrate safety and increase uptake, vaccine hesitancy has increased dramatically. This study aimed to systematically analyze available literature on vaccine hesitancy in the United States and determine the rationale behind vaccine-hesitant parents and potential interventions. ⋯ Despite large amounts of research on vaccination rates, patients are still reporting not enough information and safety as the most common reasons for vaccine hesitancy. Interventions were few and without promising results. More research was the most suggested intervention. Such research must address concerns of the vaccine-hesitant community, comparing risks and benefits of each vaccination in a longitudinal, coherent, and transparently unbiased fashion.
