1 We evaluated the willingness of accepting COVID-19 vaccines through participants responded with five options (very unlikely, somewhat unlikely, somewhat likely, very likely, and unsure). When a participant responded, “very likely” or “somewhat likely”, it was defined that the participant had a positive willingness of accepting COVID-19 vaccines. 2 The p-value was calculated using the chi-square test with effect size presented as coefficient of contingency. * p-value < 0.05; ** p-value < 0.01; *** p-value < 0.001. Abbreviation: COC, coefficient of contingency; CCI, Charlson Comorbidity Index.
