Note: Adjusted odds ratios were calculated for the outcome of intention of free COVID-19 vaccination with adjustment for department and were calculated for the outcome of intention of self-paid COVID-19 vaccination with adjustment for department and education level. † p < 0.1; * p < 0.05; ** p < 0.01; *** p < 0.001.
