Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a post-marketing case-controlled study of the effectiveness of a quadrivalent live attenuated influenza vaccine (Q/LAIV/FluMist® Quadrivalent) versus Inactivated Influenza Vaccine (IIV) and No Vaccine in subjects 2-17 years of age.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
