Clinical Trial Summary

The purpose of this study is to describe the immunogenicity of the prototype Quadrivalent Influenza Vaccine (QIV) compared with the 2009-2010 Trivalent Influenza Vaccine (TIV) and the 2008-2009 TIV among children and adults.

Primary Objective:

To describe the immunogenicity of the prototype Quadrivalent Influenza Vaccine (QIV) compared with the 2009-2010 Trivalent Influenza Vaccine (TIV) and the 2008-2009 TIV among adults.

Observational Objectives:

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Number of Adult Participants With Seroprotection Against Influenza Vaccine Antigens Following Vaccination With Fluzone® Quadrivalent Influenza Vaccine or Trivalent Influenza Vaccine	Immunogenicity outcomes were assessed in serum samples by HAI assay. The lower limit of quantitation (LLOQ) was set at the lowest dilution used in the assay, 1/10. Titers below this level were reported as <10.; Seroprotection to vaccine antigens was defined as a pre-vaccination and post-vaccination titer value of titer = 40 (1/dil)	Day 0 (pre-vaccination) and Day 21 post final vaccination	No
