Summary

Vaccine uptake in the United States is lower in rural areas, especially for HPV vaccine. Reminder/recall has been identified as an effective strategy to increase vaccination rates. This study will assess the impact by rurality of vaccine reminder notices sent via the parent's preferred method of communication on HPV vaccination among 12 year-old patients in a regional healthcare system.
