Differential maternal responses to a newly developed vaccine information pamphlet

We compared the response to a new vaccine information pamphlet with the current CDC Vaccine Information Statements (VIS) among recently delivered mothers who were screened to identify those with concerns about immunization. Eligible mothers (n=226) were randomly assigned to one of three equal groups; those reviewing only the new pamphlet, those receiving only VIS, or those receiving both. Among those mothers reviewing both, 61% preferred the new pamphlet for its visual appeal (P<0.0001) and ease of understanding (P=0.005). Overall, mothers expressed increased confidence and fewer concerns regarding multiple injections after reviewing the pamphlet. However, older, more-highly educated mothers were less likely to report improved vaccine confidence after reviewing either the pamphlet or the VIS. Mothers in all three groups stated a preference for receiving the vaccine information during pregnancy or prior to the actual immunization visit. These data suggest that early provision of tailored immunization material along with the VIS to new mothers may enhance their overall confidence in vaccines and that additional strategies targeted toward certain mothers may be needed.
