This article presents findings on the personality traits of individuals who identified as either Vaxxers (V) or Anti-Vaxxers (AV) during the COVID-19 pandemic. The study administered measures of Dark Triad traits (Machiavellianism, Narcissism, and Psychopathy), trait emotional intelligence, and personality to a sample of 479 participants (283 Vs and 196 AVs) recruited via mTurk. Results indicated that Vaxxers scored higher on HEXACO Honesty and Conscientiousness while Anti-Vaxxers scored higher on the Dark Triad and trait emotional intelligence. These findings contribute to the understanding of personality differences between Vaxxers and Anti-Vaxxers during a public health crisis.
