Arms & Interventions
Study Group
Participants received one dose of Fluzone® vaccine on Day 0.
Intervention: Split, Inactivated, Trivalent Influenza vaccine (Fluzone®) (Biological)
Outcomes
Primary Outcomes
Percentage of Participants With at Least a 4-Fold Rise in Hemagglutination Inhibition Antibody Titer Post-Vaccination With Fluzone Vaccine (Seroconversion)
Time Frame: 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 Formulation
Time Frame: Day 0 and 21 days post-vaccination
Number of Participants With at Least 1 Solicited Injection Site Solicited Systemic Reactions Post-vaccination With Fluzone® Vaccine.
Time Frame: 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)
Time Frame: 21 days post-vaccination
Seroprotection was defined as post-vaccination titer value of ≥ 1:40.
Secondary Outcomes
No secondary outcomes reported
