A feasibility study assessing knowledge, vaccine hesitancy, and completion rates of free HPV vaccination in low-income uninsured adults

Background: Human Papillomavirus (HPV) vaccination rates remain low in the U.S., particularly among minorities and low-income, uninsured patients. We report preliminary data on a pilot study program providing education and free HPV vaccination at a clinic serving low-income uninsured adults.

Methods: From October 2020 through October 2022, we assessed HPV vaccination knowledge, awareness, and prevalence of hesitancy towards receiving the vaccine among low-income uninsured patients age 18-45. The Parents Attitudes about Childhood Vaccines (PACV) survey was modified and used to evaluate vaccine hesitancy. An educational video on HPV was shown to patients declining vaccination.

Results: 43 patients were enrolled. 69.8% had heard of the HPV vaccine and 85.7% were non-hesitant based on PACV scores of 0-49. Black participants had a statistically significant higher PACV score (more hesitant) than White participants. Familiarity with the HPV vaccine correlated with lower PACV scores. Only 27% completed all three HPV vaccine doses.

Discussion: The availability of an education program together with free HPV vaccination are not sufficient to achieve adequate vaccination rates in low-income, uninsured adults. Innovative, culturally sensitive education and supportive interventions, in addition to access to free HPV vaccination, are warranted in order to improve vaccination rates in this underserved population.
