Parents' decisions about HPV vaccine for sons: the importance of protecting sons' future female partners.

Parents' decisions about human papillomavirus (HPV) vaccine for sons may be influenced by potentially protecting sons' future female partners from HPV. We sought to identify characteristics of parents likely to consider future partner protection in vaccine decisions, and to determine if parents likely to consider future partners in vaccine decisions had greater intention to vaccinate. We performed a cross-sectional survey of parents with sons in a pediatric clinic in 2010. We used Fisher's exact tests to identify demographics associated with consideration of future female partners in vaccine decisions. We used adjusted logistic regression to determine if parents likely to consider future partner protection in vaccine decisions had greater intention to vaccinate sons. Most parents (76 %, 187/246) reported vaccine decisions for sons were likely to be influenced by preventing HPV transmission from sons to their female partners. Parents 40 years and older, White and Black parents (vs other race), non-Hispanic, and college-educated parents were significantly more likely to indicate female partner protection may influence vaccine decisions (p < 0.05). Parents likely to be influenced by female partner protection in vaccine decisions had greater intention to vaccinate sons than their counterparts (adjusted odds ratio 2.54, 95 % CI 1.22, 5.28). Overall, many parents were likely to consider sons' female partners in vaccine decisions. Because parents likely to consider female partners had increased intention to vaccinate sons, future efforts to improve vaccine uptake in boys should explore the benefits of highlighting potential female partner protection, as this concept may resonate with many parents.
