Brief Summary

Primary Objective:

To evaluate for each influenza strain the non-inferiority of Investigational Fluzone vaccine to the standard Fluzone® vaccine in healthy subjects aged 6 to 35 months or 3 to 8 years.

Secondary Objectives:

* To describe the immunogenicity of of Investigational Fluzone vaccine to the standard Fluzone® vaccine in healthy subjects aged 6 to 35 months or 3 to 8 years.

* To describe the safety of of Investigational Fluzone vaccine to the standard Fluzone® vaccine in healthy subjects aged 6 to 35 months or 3 to 8 years.

Primary Outcome Measures
NameTimeMethod
Geometric Mean Titers (GMTs) Before and Post Vaccination With Either a Fluzone Intradermal or a Fluzone Intramuscular VaccineDay 0 and Day 28 post-vaccination

Antibody titers against each strain of influenza hemagglutinin were measured in the sera using the hemagglutination inhibition (HI) technique.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants That Achieved A 4-Fold Rise in Serum HAI Antibody Titer Post-vaccination With Either a Fluzone Intradermal or a Fluzone Intramuscular VaccineDay 28 post-vaccination

Antibody titers against each strain of influenza hemagglutinin were measured in the sera using the hemagglutination inhibition (HI) technique.

Percentage of Participants That Achieved Seroprotection Before and Post-vaccination With Either a Fluzone Intradermal or a Fluzone Intramuscular VaccineDay 28 post-vaccination

Seroprotection was defined as participants achieving a post-dose antibody titers ≥40.

Antibody titers against each strain of influenza hemagglutinin were measured in the sera using the hemagglutination inhibition (HI) technique.

Percentage of Participants That Achieved Seroconversion Post-vaccination With Either a Fluzone Intradermal or a Fluzone Intramuscular VaccineDay 28 post-vaccination

Seroconversion was defined as the conversion to a post-vaccination titer of ≥ 40 for subjects with pre-vaccination titer \< 10, or at least a 4-fold increase in post vaccination titer for subjects with pre vaccination titer ≥ 10.

Number of Participants Reporting a Solicited Injection Site or Systemic Reactions After Each Vaccination With Either a Fluzone Intradermal or a Fluzone Intramuscular Vaccine - Age 6 to 35 Months.Day 0 to Day 7 post-vaccination

Solicited injection site reactions: Tenderness, Redness, Swelling, Induration and Ecchymosis. Solicited Systemic reaction: Fever (Temperature), Vomiting, Abnormal crying, Drowsiness, Loss of Appetite, and Irritability.

Number of Participants Reporting a Solicited Injection Site or Systemic Reactions After Each Vaccination With Either a Fluzone Intradermal or a Fluzone Intramuscular Vaccine - Age 3 to 8 Year OldsDay 0 to Day 7 post-vaccination

Solicited injection site reactions: Pain, Redness, Swelling, Induration and Ecchymosis. Solicited Systemic reaction: Fever (Temperature), Headache, Malaise, and Myalgia.
