Expert opinion in mental disorder: Why is acceptance of the COVID-19 vaccines so problematic?

A substantial number of people say they will probably or definitely not have a vaccine for COVID-19. We place the reasons for vaccine hesitancy and refusal into three categories: fears that the vaccines are not safe, misinformed ideas, and agreement with conspiracy theories. Evidence-based approaches are available that account for the psychological factors underlying vaccine hesitancy and refusal that should form the basis for counteracting facts and persuasion.
