Interventions

Informational Animation Video

The informational animation video will also take several minutes and will cover human papillomavirus (HPV) disease, address specific concerns when identified, and the importance and safety of HPV vaccines.

Personal Narrative Video

Personal narrative videos will consist of someone describing the person's own personal experience with HPV. The investigators have a collection of videos of personal narratives from different people that the investigators have cut to approximate several minutes in length so the investigators can tailor the personal narratives to match each study participant's race/ethnicity and gender as closely as possible.

Primary outcome measure

  • Number of participants who receive vaccine [ Time Frame: 9-month follow-up ]
