Sponsor's own description
This phase IV trial examines the impact of an education program on the human papilloma virus (HPV) and its effects on the acceptance and completion rates of a free HPV vaccination program in underserved adult patients. Participating in the HPV educational program may increase the HPV vaccination rates among low income uninsured adult patients and ultimately prevent HPV related cancers.
