Abstract
Influenza vaccines are universally funded in Ontario, Canada. Some public health units (PHUs) vaccinate children in schools. We examined the impact of school-based delivery on vaccination rates and healthcare use of the entire population over seven influenza seasons (2000–2007) using population-based survey and health administrative data. School-based vaccination was associated with higher vaccination rates in school-age children only. Doctors’ office visits were lower for PHUs with school-based vaccination for children aged 12–19 but not for other age groups. Emergency department use and hospitalizations were similar between the two groups. In the context of universal influenza vaccination, school-based delivery is associated with higher vaccination rates and modest reductions in healthcare use in school-age children.
