Outcome Measures
Primary Outcomes (1)
To demostrate that the efficacy over one season against culture-confirmed influenza-illness caused by community-acquired subtypes antigenically similar to those contained in the vaccine
Secondary Outcomes (3)
To demostrate that the efficacy over one season of CAIV-T is not inferior to that of TIV against culture-confirmed influenza-illness of any subtype
To demonstrate that the efficacy of CAIV-T is not inferior to that of TIV against clinically-defined acute otitis media
To compare the rate of occurence over a defined surveillance period in children with a histroy of recurrent RTIs
