COVID-19 Vaccination and Mental Disorders, What Has Been Accomplished and Future Direction.

The consequences of the pandemic on mental health are among the most important side effects of COVID-19. Wide concerns have emerged both regarding vaccine hesitation in the general population, and the vaccine's implementation plan. The aim of this study is to evaluate how the scientific community has investigated the relationship between the COVID-19 vaccine and mental disorders. Contrary to expectations, having a full-blown psychiatric pathology seems to positively affect the attitude towards the vaccine, except for PTSD. The intense fear that accompanied the current world emergency has made this pandemic unique; we discuss how it might be one of the factors involved in this result. Further experimental investigations are needed to estimate how personality traits, hyperarousal, and negative emotions influence vaccine compliance both in the general population and in people living with mental disorders.
