Several studies showed varying trends of vaccine hesitancy rates among different countries. Major factors involved in vaccine hesitancy in general include mistrust, misinformation, believing in conspiracy theories, and negative attitudes towards vaccines. It was surprising that none of the studies were focused on vaccine acceptance rates and factors associated with vaccine hesitancy among the mentally ill population. However, studies do show that COVID-19 is associated with worse healthcare outcomes for psychiatric patients, and vaccine hesitancy correlated with a lower likelihood of receiving mental health treatment and vaccinations. Psychiatrists need to address issues among patients who are particularly vulnerable to the fear of vaccines which include anxiety, panic attacks, certain phobias including trypanophobia and agoraphobia, obsessive-compulsive disorder, and certain types of traumas. Psychiatrists need to communicate effectively, show respect, empathy, and deliver accurate and honest information about the vaccines.
