*Model also contained additional variables: Seriousness of illness, duration of illness, vaccine effectiveness, risk of illness without vaccination, risk of death without vaccination, risk of severe side effects, length of time vaccine available, location, time, healthcare provider type, PCP recommendation, and cost after insurance

†Indicates that odds ratio is significantly different from 1 (p < 0.05)
