Importance of human papillomavirus vaccination leaflets focusing on the safety profile targeted pediatricians in Japan.

OBJECTIVES

To investigate the association between providing leaflets to support pediatricians in explaining the safety of the human papillomavirus (HPV) vaccine and mother's decision to vaccinate their daughters in Japan.

METHODS

In this cross-sectional study, we conducted a survey of mothers to evaluate the effect of leaflets that were created to support pediatricians in explaining the safety profile of the HPV vaccine. Mothers who provided consent for vaccination before receiving an explanation were excluded from the study. The primary outcome was the mother's decision to vaccinatetheir daughters with the HPV vaccine after receiving an explanation from pediatricians using our leaflets.

RESULTS

Among 161 eligible mothers, 101 decided on HPV vaccination (decided group) and 60 did not (decided against group). There was no difference in the maternal background between the 2 groups. The decided group had a significantly more positive impression of the leaflets than the undecided group. In multivariable logistic regression analysis, a detailed explanation for possible adverse events and specific solutions to them was associated with the mother's decision to have their daughters vaccinated (odds ratio 2.35, 95% confidence interval 1.02-5.44), but not the pathology of cervical cancer and the HPV vaccination process.

CONCLUSION

Leaflets emphasizing an explanation of adverse events may contribute to mothers' decision making for HPV vaccination.
