Percentage of Subjects With Seroprotection, in Healthy Adults 18 to 64 Years of Age
Aikaikkuna: 21 days after vaccination
|
To evaluate immunogenicity, measured by seroprotection (percentage of subjects achieving a hemagglutination inhibition [HI] titer ≥40) after one injection of the investigational influenza virus vaccine, administered to healthy adults 18 to 64 years of age.
The CBER Guidance states that the lower bound of the two-sided 95% CI for the percentage of subjects achieving seroprotection meet or exceed 70%.

21 days after vaccination

|
Percentage of Subjects Achieving a Seroconversion Rate, in Adults 18 to 64 Years of Age
Aikaikkuna: 21 days after vaccination
|
Seroconversion rate is defined as percentage of subjects achieving seroconversion (defined as negative pre-vaccination serum [HI<10]/ post-vaccination HI titer ≥40) or significant increase defined as at least a 4-fold increase).
According to the CBER Guidance, the lower bound of the two-sided 95% CI for the percentage of subjects achieving seroconverion/significant increase meet or exceed 40%.
