Primary Outcome Measures:
  • To compare the families of children in the target schools with families of children in the control schools with respect to workdays lost by adults and school days lost by children. [ Time Frame: 7 days after each vaccination ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Absenteeism - To compare the families of children in the target schools to those in the control schools with respect to the overall increase in absenteeism during the influenza outbreak, using aggregated (summary) absentee rates. [ Time Frame: between outbreak and non-outbreak weeks ] [ Designated as safety issue: No ]
  • Herd Community - To compare unvaccinated children in the target schools to the children in the control schools with respect to changes in absentee rates between outbreak weeks and non-outbreak weeks. [ Time Frame: between outbreak and non-outbreak weeks ] [ Designated as safety issue: No ]
