Brief summary

The cocooning strategy, which was implemented in Australia in 2009, can have a strong protective effect (indirect) against pertussis in infants. To achieve high maternal coverage, understanding maternal attitudes and other potentially influential factors is important. In this study, we examined the influence of baseline attitudes, modifiable factors and health message framing on pertussis booster vaccine uptake among postpartum women in the public hospital setting.

Interventions

Health-message framing: The tri-fold, coloured A4 pamphlet was written either in a gain or loss frame, indicating either what mothers gain from the cocooning strategy or what mothers would lose by not receiving the pertussis booster vaccine (for adults). The intervention was administered by the research nurse once the baseline questionnaire was completed. The interventions ( gain or loss pamphlet) were allocated to participants using sequential block allocation by week.
