Abstract
Low uptake of human papillomavirus (HPV) vaccine calls for innovative approaches. Offering the vaccine in settings outside the traditional medical home, such as schools and pharmacies, could increase use. We sought to characterize the acceptability of HPV vaccine delivery in these alternative settings using a national (US) sample of parents of adolescent males ages 11-17 y (n = 506) and their sons (n = 391) who completed our online surveys in Fall 2010. We used multivariable regression to identify correlates of parents' and sons' comfort with (i.e., acceptability of) alternative settings. Half of parents (50%) and over one-third of sons (37%) reported that they were comfortable with schools or pharmacies as locations for the sons to receive HPV vaccine. Parents and sons were more comfortable with HPV vaccination in alternative settings if the sons had not recently visited their health care providers or had previously received vaccines at school, or if parents and sons were comfortable talking with each other about new vaccines. Parents who perceived greater barriers to HPV vaccination were more comfortable with alternative settings, as were sons who perceived that their peers were more accepting of HPV vaccine (all p < 0.05). Offering HPV vaccine in alternative settings may increase vaccination, especially among hard-to-reach adolescents. For example, our results suggest that offering the vaccine in alternative settings to boys who had not had recent health care visits could increase uptake by more than 10%. Study findings also highlight factors that should be addressed to maximize the potential success of HPV vaccination programs.
