The overall objective of this study is to provide ongoing assessment of the safety and effectiveness of seasonal and pandemic H1N1 vaccines in the prevention of ILI (influenza like illness), ILI-associated work absenteeism, and laboratory-confirmed influenza in a cohort of Canadian HCP (Health care providers). Given the uncertainties around the timing of the provision of seasonal influenza immunization to HCP for the 2009/10 influenza season, this study will focus on evaluation of safety and effectiveness of pandemic influenza immunization in Year 1 and evaluation of all recommended influenza vaccines in Years 2 and 3.
