Adolescent Male Human Papillomavirus Vaccination.

Objective. To determine male vaccination rates with quadrivalent human papillomavirus vaccine (HPV4) before and after the October 2011 national recommendation to routinely immunize adolescent males. Methods. We reviewed HPV4 dose 1 (HPV4-1) uptake in 292 adolescent males in our urban clinic prior to national recommendations and followed-up for HPV4 series completion rates. After national recommendation, 248 urban clinic and 247 suburban clinic males were reviewed for HPV4-1 uptake. Factors associated with HPV4-1 refusal were determined with multiple logistic regression. Results. Of the initial 292 males, 78% received HPV4-1 and 38% received the 3-dose series. After recommendation, HPV4-1 uptake was 59% and 7% in urban and suburban clinics, respectively. Variables associated with HPV4-1 uptake/refusal included time period, race, type of insurance, and receipt of concurrent vaccines. Conclusions. HPV4-1 vaccination rates in our urban clinic were high before and after routine HPV vaccine recommendations for adolescent males. Our vaccination rates were much higher than in a suburban practice.
