Further study details as provided by MedImmune LLC:

Primary Outcome Measures:
  • To demostrate that the efficacy over one influenza season against culture-confirmed influenza illness caused by community-acquired subtypes antifenically similar to those contained in the vaccine

Secondary Outcome Measures:
  • To demonstrate that the efficacy over one season of a single dose of CAIV-T was not inferior to that of one dose of TIV against culture-confirmed influenza-illness of any subtype
  • To compare the efficacy over a defined surveillance period against asthma exacerbations, asthma medication, clinical visits, hospitalizations, days off school (pharma-ecomonic measures) associated with influenza-like illness

Estimated Enrollment: 2229
Study Start Date: October 2002
Estimated Study Completion Date: May 2003
Detailed Description:
- To assess asthma exacerbation, being defined as acute wheezing illness associated with hospitalization, unscheduled clinic visits, or new prescriptions from study vaccination through to the end of the study.
