a

Counts are raw pooled counts with weighted percentages (W%)

b

Based on DAG: age, gender, education, family income, healthcare/transportation challenges, lifetime alcohol use, current smoking status, and current e-cigarette status

c

Among respondents with no previous vaccine doses (n=221 with CHC, n=154 without CHC)
