*Values are reported as % respondents (95% CI). n values indicate unweighted sample size/denominator. Bold text indicates statistical significance (p<0.05) between reachable and reluctant groups; reluctant group is the referent. R respondents were defined as adults who probably would or were unsure about getting a COVID-19 vaccine. RL respondents were defined as adults who probably or definitely would not get a COVID-19 vaccine. COVID-19, coronavirus disease; R, reachable; RL, reluctant.
