Abstract
Vaccine hesitancy—the reluctance, delay, or refusal to vaccinate regardless of availability—is not a new concept in psychology, medicine, or public health. However, given the emotions surrounding the COVID-19 vaccine, hesitancy has proven difficult to overcome. To-date, the bulk of available data on vaccine hesitancy are quantitative, leaving room for exploratory investigations into the reasons adults remain unvaccinated. This qualitative study assessed the motivations, beliefs, and perceptions of individuals who have decided to remain unvaccinated against COVID-19. We had one exploratory research question: What social psychological justifications emerge from vaccine hesitant people’s explanations of their decisions to remain unvaccinated? To assess this question, we conducted 18 interviews with unvaccinated adults throughout 2021–2022. The interviews consisted of 20 questions regarding participants’ perceptions of the COVID-19 vaccine and their intentions to get vaccinated. Thematic analysis revealed four main themes in the answers provided by participants: rationalization; identity, beliefs and potential modifiers; emotional responses; and information sources. These results offer insight for future vaccination efforts.
