Over the course of one year, six Facebook advertising campaigns were developed to direct adolescents to the 3forME Facebookpage and website. Adolescents with a Facebook account who self-identified as 13-18 years of age and living in Philadelphia were prioritized to receive advertisements. Advertisements, which ran for two-week periods, were displayed on the right side of the Facebook login page and varied by themes, images, and text, each linking to HPV immunization. Additionally, we sent reminder-recall letters to adolescents who were due for HPV vaccine at two city health centers where we held weekly vaccine clinics.
