This paper investigates the determinants of a Colorado College student’s being vaccinated for the human papillomavirus (HPV). Data consists of healthcare information, personal information, socioeconomic information, and information regarding one’s knowledge of and exposure to HPV and HPV advertisements for ninety-five students. A Logit regression model is used to determine the factors that influence HPV vaccination completion rates. Sexual preference, current standing in school, doctor recommendations, vaccine advertisements, and the religious practices of a student’s father are significant determinants.
