A Study to Evaluate the Safety and Immune Responses to Fluzone® Vaccination

Phase 4

Completed

• Conditions: Influenza

• Registration Number: NCT00835926
• Lead Sponsor: Sanofi Pasteur, a Sanofi Company

Brief Summary

To describe the safety during days 0 to 21 following injection of the 2003-2004 formulation of the inactivated, split-virion influenza vaccine Fluzone® in subjects aged 18-59 years and subjects aged ≥ 60 years.

To describe the immune response at 21 days following injection of the 2003-2004 formulation of the inactivated, split-virion influenza vaccine Fluzone®, in subjects aged 18-59 years and subjects aged ≥ 60 years.

Detailed Description

Safety will be assessed throughout the trial period. Using antigens provided by Aventis Pasteur Inc., pre- and post-vaccination serum antibody titers for each of the three vaccine strains will be measured.

Primary Outcome Measures

Name	Time	Method
Percentage of Participants With Solicited Injection Site and Systemic Reactions Post-Vaccination With Fluzone®	Days 0 to 3 Post-vaccination	Solicited injection site reactions: Erythema, bruising, induration, and Pain at injection site.; Solicited systemic reaction: Fever (temperature), chills, rash, headache, cough, runny nose, nausea, vomiting, diarrhea, malaise, myalgia, and arthralgia
Geometric Mean Titers (GMTs) of Hemagglutination Inhibition Antibodies Before and After Vaccination With Fluzone®	Day 0 and Day 21 Post-vaccination	Hemagglutination inhibition antibodies is a measure of the serum antibody to the influenza virus in the vaccine as determined by the hemagglutinin inhibition (HAI) assay.
Percentage of Participants With a ≥ 4-Fold Rise in Serum Hemagglutination Inhibition Antibody Titers Post-Vaccination With Fluzone®	Day 21 Post-vaccination	Hemagglutination inhibition antibodies is a measure of the serum antibody to the influenza virus in the vaccine as determined by the hemagglutinin inhibition (HAI) assay.
Percentage of Participants With Serum Hemagglutination Inhibition Antibody Titers ≥ 40 Post-Vaccination With Fluzone®	Day 21 Post-vaccination	Hemagglutination inhibition antibodies is a measure of the serum antibody to the influenza virus in the vaccine as determined by the hemagglutinin inhibition (HAI) assay
