What this trial studies

This intervention focuses on educating underserved populations about the importance of the HPV vaccine through workshops led by trained Community Health Educators. Participants will receive educational materials developed by the National Cancer Institute, including presentations and videos, aimed at adolescents and young adults who have not started or completed the HPV vaccine series. The study will assess the effectiveness of this educational intervention using pre- and post-tests, as well as follow-up surveys to track vaccination rates and referrals to care. The goal is to enhance knowledge and increase the completion rates of the HPV vaccine among participants.

Why it matters

Potential benefit: If successful, this intervention could significantly increase HPV vaccination rates, thereby reducing the incidence of HPV-related cancers in underserved populations.

How similar studies have gone: Other studies have shown success with educational interventions aimed at increasing HPV vaccination rates, suggesting that this approach is promising.
