Study Summary

Background: Prevention of cervical cancer and genital warts could be achieved by immunization with the prophylactic human papillomavirus (HPV) vaccines commercially available. However, in the U.S. only 38% of females and 14% of males in the recommended age group (9-26 years) receive the complete, three-dose HPV vaccine. Because the HPV vaccine is covered under the Vaccine for Children Program, the underinsured and uninsured have no-cost access. Nonetheless, data from Los Angeles county suggest that HPV vaccination rates among the uninsured and underinsured groups are significantly lower than the national average, likely related to knowledge of the vaccine, transportation, number of doses and concern of side effects. Aim: To evaluate the efficacy of health oriented text messaging to increase HPV vaccine uptake versus standard health messaging (Center for Disease Control and Prevention (CDC) HPV vaccine information flyers). Hypothesis: The investigators hypothesize that receiving general health messaging, including messages regarding the benefits of the HPV vaccine, will increase HPV vaccine uptake. Text messaging will also be more successful in reaching the uninsured and underinsured populations than will traditional flyers/information pamphlets used in clinics. Methods: A cluster randomized trial design will be used to recruit participants from four clinics in Los Angeles County which offer pediatric vaccination to uninsured and underinsured children. The sample will include women aged 18-45 years of age. Two of the sites will be randomized to the text messaging arm and the other clinic will be randomized to the control arm (standard messaging: CDC flyers and pamphlets available for patients at the clinic). Outcome measures will be HPV vaccinations rates at those clinics. Rates will be defined into groups who received 1 dose, 2 doses and 3 doses. Anticipated Results: The investigators expect to find statistically significant higher HPV vaccination rates among ch

Primary Outcome

In both arms of the study, we will collect data on the number of females aged 9- 26 years who made any visit to the clinic (denominator) and the number of females aged 9-26 vaccinated (numerator). Vaccination rates will be defined into groups who received at least 1 dose, compared to receiving none. We will also examine those receiving at least 2 doses vs 1 vs none.
