Study Overview
Brief 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.

Outcomes
Primary Outcomes
Number of patients that received 1 dose of HPV vaccine during follow-up based on electronic health data
Time Frame: 90 days
Receipt of 1 dose of HPV vaccine within 90 days of receipt of reminder (yes/no) will be assessed using vaccination data available from the Marshfield Clinic Health System electronic health record, which includes vaccinations administered outside of MCHS through data exchanges with the Wisconsin Immunization Registry. Specifically patients will be classified as having received 1 dose of HPV vaccine if they have record of receipt of HPV vaccine with a vaccination date during the 90-day follow-up period.
