Vaccine Delivery System Component Flow. The HPV vaccine intervention system employed multiple evidence-based strategies to influence HPV vaccine delivery and receipt in primary care, including clinician-focused immunization alerts, education, and feedback, and family-focused telephone reminders and direction to educational content. The system was integrated with the electronic medical record (EMR) and supported an immunization history and reminder engine that was developed with logic from the CDC Immunization Schedules.
