Abstract
The role of personality traits and perceived threat on COVID-19 vaccine acceptance among undergraduates is relatively scarce. The study investigated the role of personality traits and perceived threat on COVID-19 vaccine acceptance among 374 (age = 18-28 years, M =23.23 years, SD = 2.57 years) undergraduates in Obafemi Awolowo University, Ile-Ife, Nigeria. A cross-sectional survey design was utilized. A self-administered questionnaire was used to gather information about socio-demographics, HEXACO personality traits, perceived threat and COVID-19 Vaccine acceptance. Results showed a significant influence of personality traits on COVID-19 vaccine acceptance. Findings also revealed that perceived threat significantly predict COVID-19 vaccine acceptance among undergraduates. Result further showed that there was a significant influence of religion on COVID-19 vaccine acceptance (t (372) = −2.13, p = .034, 95% CI (−6.44, −.25), d = 0.22.) These results emphasize the importance of HEXACO personality traits and perceived threat when considering program targeted at COVID-19 vaccine acceptance among undergraduates.
