Experimental: Study Group
Participants received one dose of Fluzone® vaccine on Day 0.
Biological: Split, Inactivated, Trivalent Influenza vaccine (Fluzone®)
0.5 mL, intramuscular
Other Name: Fluzone®
- 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
- 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 ]
- 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.
- 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
