School-based influenza vaccine delivery, vaccination rates, and healthcare use in the context of a universal influenza immunization program: an ecological study.
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.
