Integrating HPV Education Into School Health Programs in Cambodia and Kenya

The Clinton Health Access Initiative conducted a mixed-methods, school-based interventional study in Cambodia and Kenya to evaluate whether integrating age-appropriate human papillomavirus (HPV) education into existing school health education improves HPV vaccination coverage and students' knowledge and awareness of HPV, HPV vaccination, and cervical cancer. The study also assessed HPV vaccine-related attitudes and the feasibility, acceptability, and cost of the integrated education model. Schools were assigned to intervention or control using setting-specific procedures that combined geographic structuring and random elements rather than uniform school-level randomization. Intervention schools received integrated HPV education, while control schools continued existing curricula without the study-added package. Routine HPV vaccination eligibility, products, schedules, supply, and delivery arrangements were unchanged. Quantitative outcomes were assessed at baseline and endline using school immunization records and repeated cross-sectional student knowledge, attitudes, and practices questionnaires. Qualitative interviews with caregivers, teachers, and healthcare workers examined HPV-related knowledge, vaccination perceptions, accessibility, and implementation feasibility and acceptability. A costing analysis estimated intervention cost per immunization administered. The study included 46 schools in Cambodia and 160 in Kenya.

Stories to Prevent (StoP) HPV Cancers

This randomized controlled trial (RCT) evaluates the association of a narrative communication intervention on human papillomavirus (HPV) vaccination rates among 9- to 12-year-olds. The intervention is a brief video from local cancer survivors narrating their stories with an HPV-related cancer diagnosis and recommending the HPV vaccine for cancer prevention. RCT participants will be the parents (n=200) of children ages 9-12 who have not initiated HPV vaccination. Participants will be randomized (1:1) to our intervention or control (placebo video) one week before their child's next primary care visit. Our primary outcome is HPV vaccine initiation (first dose of the HPV vaccine series) among children ages 9-12 at the time of the wellness visit. The study also explores the effect of narratives on theory-based mediators of HPV vaccination, including parents' cognitive (e.g., risk perception) and emotional reactions (e.g., hope, anticipated regret).

HPV Vaccine Reminders - SEARCH II Study

This RCT will take place at health centres and their affiliated schools and community immunization centers overseen by the Kampala Capital City Authority (KCCA) as well as at the Makerere/Mulago/Columbia Adolescent Health Clinic in Kampala. The investigators will assess the impact of vaccine text message and automated phone reminders on human papillomavirus (HPV) vaccination initiation and completion.
