Factors Associated with Initiating but not Completing the HPV Vaccination

Thee purpose of the study was to examine social in uences and healthcare characteristics on vac-cination completion among females who initiated the process. Questionnaire data were analyzed from 536females and 20.1% initiated the HPV vaccination but did not complete. Relative to women who com-pleted the vaccination, those who were older at time of vaccine initiation (P<0.001) and reported a parentdecision to vaccinate (P<0.001) were more likely to have initiated but not completed the cycle. Highersocial in uence to be vaccinated scores were associated with initiating but not completing the vaccination(P=0.017). These findings can guide health promotion interventions to encourage vaccine completion.
