 Phase 2 - Randomized controlled trial. Investigators will select and invite 1200 families whose daughter has an upcoming appointment at one of four Parkland clinic sites. Eligible patients will be randomized to either the Intervention group or the General Adolescent Vaccine Brochure group. The Intervention group participants will be mailed a packet containing an invitation letter to join the study and HPV vaccine-specific educational materials; General Adolescent Vaccine Brochure group participants will be mailed a packet with educational materials on all four of the recommended adolescent vaccines HPV, meningococcal, TDAP, and influenza. A few days after the packet has been sent, a research assistant will call participants to verify that the letter was received and assess interest in completing a pre-clinic visit survey.
