The overall objective is to document geographic variability in HPV vaccine series completion across the state of Indiana and to identify factors associated with low versus high rates of completion. Objective a: To map HPV vaccine series completion rates across Indiana's 92 counties for children aged 14 years and younger. Hypothesis: The investigators expect wide variability in completion rates from county to county. Further, the investigators expect significantly less variability in county-level administration of vaccines required for middle-school entry (Tdap, MenACWY, and HepA vaccines). Objective b: To identify county-level characteristics associated with HPV vaccine series completion rates across Indiana's 92 counties. Hypothesis: The investigators expect factors reflective of pragmatic obstacles to be associated with lower completion rates: such as lower population density, fewer primary health care providers (HCP) per capita, longer commute to work, lower median household income, and lower rates of insurance coverage of children.
