Note: Odds ratios represent the likelihood that the participant is willing to receive a COVID-19 vaccine, as compared to those who are unsure or unwilling to receive the vaccine.
aAdjusted model includes age and education as co-variates. Education remained significant in the adjusted model; age did not remain significant.
