简要总结
To assess the safety of a bivalent vaccine of two new influenza virus reassortants in healthy adults prior to the release of the trivalent vaccine (FluMist) containing them.
详细描述
This prospective, randomized, double blind, placebo-controlled release study will enroll approximately 300 healthy adults 18-49 years of age. Eligible subjects will be randomly assigned in a 4:1 fashion to receive a single dose of bivalent vaccine or placebo by intranasal spray. This study will be conducted at multiple sites in the United States. Randomization will be stratified by site.

排除标准
- •History of hypersensitivity of any component of the vaccine, including egg or egg protein
- •History of hypersensitivity to gentamicin

- •Acute febrile (>100.0°F oral or equivalent) and/or clinically significant respiratory illness (e.g., cough or sore throat) within the 14 days prior to randomization
- •Any known immunosuppressive condition or immune deficiency disease, including HIV infection, or ongoing immunosuppressive therapy
- •History of Guillain-Barré syndrome

结局指标
主要结局
The primary endpoint of this study is fever (Study Days 0-7), defined as oral temperature of at least 101°F.
次要结局
- Secondary endpoints of the study include other reported REs and AEs that occur within 7 days after vaccination (Study Days 0-7) and all REs and AEs that occur within 14 days after vaccination (Study Days 0-14).
