Actual (reported)Human papillomavirus (HPV) is the most common sexually transmitted disease among adolescent females in the United States. Our primary objective is to determine if Short Message Service (SMS) text message reminders increase adherence to the recommended 3 dose schedule for Gardasil compared to usual care in an outpatient clinic setting. Secondary objectives of this study are: 1) to demonstrate the feasibility of using SMS text message reminders to increase adherence with Gardasil vaccination; and 2) to assess satisfaction and acceptability of text message reminders compared to telephone reminders among women who receive the text message arm of the intervention. The investigators hypothesize that receiving SMS text message reminders will increase adherence to the recommended 3 dose schedule for Gardasil compared to usual care.

Actual (reported)Number of Participants That Adhered to Vaccine Schedule
Our primary objective is to determine if Short Message Service (SMS) text message reminders increase number of participants that adhered to the recommended 3 dose schedule for Gardasil compared to usual care in an outpatient clinic setting.
at the end of the study (30 days after the third vaccination or 360 days after the first vaccination, whichever comes first)
Participants follow the usual practices for scheduling their follow up visit(s) for vaccination at the clinic. Participants will receive the standard reminder from the clinic for their scheduled appointment(s) (phone call, letter, etc, as appropriate).
Participants in both the Usual Care group and the SMS Text Message group will receive the standard reminder from the clinic for their scheduled appointment(s) (phone call, letter, etc, as appropriate). Women in the SMS Text Message group that reschedule a vaccination visit will receive text message reminders one per day for each of the seven days prior to the rescheduled visit.
Women in the SMS Text Message group that reschedule a vaccination visit will receive text message reminders one per day for each of the seven days prior to the rescheduled visit (or as many days as possible depending on when the rescheduled visit will take place - for example, if they call in and reschedule the visit to take place in 4 days, they will receive text messages for the 3 days prior to the rescheduled visit). Participants in both the Usual Care group and the SMS Text Message group will receive the standard reminder from the clinic for their re-scheduled appointment(s).
