School-located Influenza Vaccination Clinics for Adolescents

The overarching goal of the study was to evaluate the effectiveness and cost-effectiveness of offering school-based influenza vaccination clinics during school hours on influenza vaccination rates. A cluster-randomized trial (clustering by school) was conducted in Monroe County, NY. Twenty middle and high schools were paired based on several characteristics including urban/suburban,school grade-span (6-8th, 9-12th), school size, percent of students eligible for free or reduced school lunch, and influenza vaccination rates in the previous season among students in the school. School were randomized within pairs, with one school offering a school-based influenza vaccination clinic or and one school not offering the clinic (control).
