NCT ID NCT04611022
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether an educational video and toolkit can help more people from underserved groups start and finish the HPV vaccine series. The vaccine protects against HPV, a virus that can cause certain cancers. The trial will enroll 1,000 patients and parents at Denver Health, measuring changes in knowledge, intentions, and actual vaccine uptake.
