Primary Outcome Measures:
  • Identification of cases positive for wild-type influenza with an end-point PCR genotyping assay. [ Time Frame: Up to 6 months for each individual flu season ]
    Vaccine Effectiveness is defined as 100 x (1-odds ratio), where the odds ratio is the odds of exposures (Q/LAIV versus Inactivated Influenza Vaccine or no vaccine) among laboratory confirmed cases of flu versus controls. Effectiveness will be monitored by flu season, class of age and by influenza strain.


Biospecimen Retention:   Samples With DNA
A nasal swab specimen will be collected and tested for influenza and other viral pathogens.

Estimated Enrollment: 8760
Actual Study Start Date: December 2, 2013
Estimated Study Completion Date: April 13, 2018
Estimated Primary Completion Date: April 13, 2018 (Final data collection date for primary outcome measure)

Detailed Description:
This post-marketing study will enroll approximately 5,200 subjects 2-17 years of age who are seeking care in an outpatient setting for febrile acute respiratory illness. This study will begin in the fall of 2013 and will be completed after 4 influenza seasons (i.e.after the 2016-2017 influenza season). No investigational product will be administered in this study. A nasal swab will be obtained and tested for the presence of influenza virus and other viral pathogens. This study will be conducted at 4 sites in the United States of America. The duration of study participation for each subject is one day.
