Extensive media coverage and potential controversy about COVID-19 vaccination during the pandemic may have affected people’s general attitudes towards vaccination. We sought to describe key psychological antecedents related to vaccination and assess how these vary temporally in relationship to the pandemic and availability of COVID-19 vaccination. As part of an ongoing online study, we recruited a national (U.S.) sample of young gay, bisexual and other men who have sex with men (N = 1,227) between October 2019 and June 2021, and assessed the “4Cs” (antecedents of vaccination; range = 1–5). Overall, men had high levels of confidence (trust in vaccines; M = 4.13), calculation (deliberation; M = 3.97) and collective responsibility (protecting others; M = 4.05) and low levels of complacency (not perceiving disease risk; M = 1.72). In multivariable analyses, confidence and collective responsibility varied relative to the pandemic phase/vaccine availability, reflecting greater hesitancy during later stages of the pandemic. Antecedents also varied by demographic characteristics. Findings suggest negative effects of the COVID-19 pandemic on key antecedents of general vaccination and identify potential targets for interventions.
