Boldface used to indicate statistical significance, where p-value <.05. The regression model adjusted for the presence of parent comments in the qualitative data regarding children not being on the COVID-19 vaccination schedule (and thus not eligible to receive a vaccine); and also whether parents directly mentioned a lack of research/clinical data to support vaccination in children. This coding did not significantly contribute to the model for either category.
