Male human papillomavirus (HPV) vaccination rates remain very low. The study objective was to gain an understanding of the perceptions of HPV disease and acceptance/barriers to HPV vaccine by parents of boys aged 9 to 18 years. An anonymous, written survey was administered from January 1, 2011 to September 30, 2013 in private pediatric offices (PPOs) and public health clinics (PHCs) in Chicago, Illinois. A total of 230 PPO parents (PPOPs) and 286 PHC parents (PHCPs) completed the survey. Despite significant differences ( P < .0001) in education level, socioeconomic status, and HPV disease and vaccine knowledge/awareness between the PPOP and PHCP, there was no difference between PPOP and PHCP who would vaccinate their sons with HPV vaccine. For both groups, health care provider recommendation was the primary influence for vaccination. The major barrier to vaccination was lack of information on HPV disease/vaccine. Health care providers need to proactively discuss and use HPV vaccine in male patients.
