Abstract
Very little is known about the effect of concurrent co-vaccination on HPV series completion. This study utilized a retrospective review of a Clinical Data Repository to assess whether concurrent vaccination had an impact on HPV vaccination series completion, and whether there were differences based on age. 3371 patients who received the HPV vaccine at a single academic medical center between the years 2009–2013 were included in this analysis. The adjusted odds ratio (aOR) for effect of concurrent vaccination on series completion for the age group 9–18 was 1.32 (95% CI 1.09, 1.60). Although not statistically significant, the aOR for effect of concurrent vaccination on completion changed direction for the 19–25 age group and was 0.44 (95% CI 0.17, 1.12). This study provides preliminary evidence that pairing the HPV vaccine with one or more co-vaccines may yield a higher HPV vaccination completion rate among adolescents age 9–18.
