Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Subjects were stratified by age-strata: 3-4, 5-8 and 9-17 years and received vaccine according to their priming status: primed subjects received a 2-dose priming immunization in a previous season, whereas unprimed subjects had not. Blood samples: at Days 0 - 28 for primed subjects and subjects 9-17 years and at Days 0-56 for unprimed subjects.

Reporting Groups
  Description
Flulaval Group

subjects received Flulaval™ vaccine according to their priming status and age:

  • 3-8 years: primed subjects 1 dose at Day 0; unprimed subjects 1 dose at Day 0 and a second dose at Day 28
  • 9-17 years: 1 dose at Day 0 Flulaval vaccine was administered intramuscularly into the non-dominant deltoid.
Fluzone Group

subjects received Fluzone® Sanofi Pasteur’s vaccine according to their priming status and age:

  • 3-8 years: primed subjects 1 dose at Day 0; unprimed subjects 1 dose at Day 0 and a second dose at Day 28
  • 9-17 years: 1 dose at Day 0 Fluzone vaccine was administered intramuscularly into the non-dominant deltoid.
