Hispanic populations have low HPV vaccination rates, although the vaccine is safe and efficacious. We surveyed a low-income Hispanic population to characterize knowledge gaps about the HPV vaccine and understand factors associated with the decision to vaccinate a child to determine how physicians can enhance vaccination rates. Surveys in English and Spanish were distributed to parents of children under age 18. Statistical analysis included logistic regression. Knowledge that the vaccine can prevent invasive cervical cancer most impacted intent to vaccinate. Physician recommendation to vaccinate was far more influential in a parent's decision compared to TV and other sources. Girls are more likely to receive the HPV vaccine over boys. While physician recommendation is critical, they have minimal time for education. Our results suggest that physicians should focus on the vaccine's link to cancer prevention, leaving other knowledge areas for the interdisciplinary care team.
