a Odds Ratio in BOLD indicate significance. bThe following covariates were also included for each logistic regression model in the paired group analysis—presence of health insurance, influenza illness within the past 12 mo, concern about potential vaccine side effects, perceived influenza severity for mother, perceived influenza severity for unborn child, and perceived vaccine efficacy. These variables were insignificant in the models, and therefore not included in the above table.
