研究概览
简要总结
The purpose of this research is to demonstrate immunologic equivalence of three consecutive production lots of the subunit influenza vaccine compared to egg-derived inactivated influenza vaccine in healthy subjects 18 to 49 years of ages. In addition, this study is to show how safe and well tolerated a conventional inactivated subunit influenza vaccine, licensed in many countries outside the United States, is compared to an inactivated influenza vaccine, licensed in the United States.

结局指标
主要结局
Geometric Mean Titers (GMTs), by Vaccine Lots
时间窗: 21 days after vaccination
The immunologic equivalence of three consecutive production lots of the influenza virus vaccine was measured in terms of GMTs for all vaccine influenza strains.
次要结局

- Geometric Mean Titers (GMTs), by Vaccine Group and Strain(21 days after vaccination)
- Number of Subjects Reporting Solicited Local and Systemic Symptoms(7 days after vaccination)
- Percentage of Subjects With Seroprotection and Seroconversion (Strain A/H1N1)(21 days after vaccination)
- Percentage of Subjects With Seroprotection and Seroconversion (Strain A/H3N2)(21 days after vaccination)
- Percentage of Subjects With Seroprotection and Seroconversion (Strain B)(21 days after vaccination)
