Risk of vaccine hesitancy among pregnant women compared to mothers of young children adjusted for Functional VL score: OR 2.53(95 %CI 2.08, 3.09).

Risk of vaccine hesitancy among pregnant women compared to mothers of young children adjusted for Interactive VL score: OR 1.63(95 %CI 1.31, 2.02).

CI = confidence interval; VL, vaccine literacy.
