Primary Outcome Measures
NameTimeMethod
Percentage of Participants With at Least a 4-Fold Rise in Hemagglutination Inhibition Antibody Titer Post-Vaccination With Fluzone Vaccine (Seroconversion)21 days post-vaccination

Seroconversion was defined as a four-fold rise in titers or greater from baseline. If the baseline titer value is \< 10, then 10 is used as the baseline value for the purposes of this calculation

Geometric Mean Titers (GMTs) for the 3 Influenza Strains Pre- and Post-vaccination With Fluzone® Vaccine 2008-2009 FormulationDay 0 and 21 days post-vaccination
Number of Participants With at Least 1 Solicited Injection Site Solicited Systemic Reactions Post-vaccination With Fluzone® Vaccine.Days 0-3 post-vaccination

Solicited Injection Site Reaction: Pain, Erythema, Swelling, Induration, and Ecchymosis. Solicited Systemic Reaction: Fever (temperature), Headache, Malaise, Myalgia, and Shivering

Percentage of Participants With at Least 1:40 Hemagglutination Inhibition Antibody Titer Post-Vaccination With Fluzone® Vaccine (Seroprotection)21 days post-vaccination

Seroprotection was defined as post-vaccination titer value of ≥ 1:40.
