Initiative Description: A local public health agency initiated school-based influenza vaccination in two Wisconsin elementary schools during October 2010 (exposed schools); two nearby schools served as a comparison group (non-exposed schools).
Study Results: School-based influenza vaccination was associated with reduced absenteeism due to fever or cough illness, but not absenteeism for other reasons.
