---|---|---|---|---|
Primary | Number of Subjects With Culture-Confirmed Influenza Illness Caused by Vaccine-like Strains | The vaccine efficacy of CCI and IVV vaccines was estimated relative to Placebo group as the number of subjects prevented against virus-confirmed symptomatic influenza illness caused by each of three vaccine-like virus strains. | 6 Months | |
Secondary | Number of Subjects With Culture-confirmed Influenza Illness Caused by Non-Vaccine Like Strains | The vaccine efficacy of CCI and IVV vaccines was estimated relative to placebo group as the number of subjects prevented against virus-confirmed symptomatic influenza A or B illness caused by non-vaccine-like strains. | 6 Months | |
Secondary | Number of Subjects With Influenza Caused by Vaccine-like and Non-vaccine-like Strains | The vaccine efficacy of CCI and IVV vaccines was estimated relative to placebo as the number of subjected prevented against virus-confirmed symptomatic influenza A or B illness caused by vaccine-like and non-vaccine-like strains. | 6 Months | |
Secondary | Influenza-Associated Days in Bed, All Subjects | The number of subjects in this analysis included all subjects in the per protocol efficacy population. | 6 Months | |
Secondary | Influenza-Associated Days in Bed, Subset of Subjects With Virus-Confirmed- Influenza | The analysis was done among the subset of subjects in the per protocol efficacy population who had culture-confirmed influenza. | 6 Months | |
Secondary | Number Of Medical Visits (Inpatient and Outpatient) Due to Influenza Illness or Symptoms of Influenza, All Subjects | The number of subjects in this analysis included all subjects in the per protocol efficacy population. | 6 Months | |
Secondary | Number of Medical Visits (Inpatient and Outpatient), Subset of Subjects With Virus-Confirmed-Influenza | The analysis was done among the subset of subjects in the per protocol efficacy population who had culture-confirmed influenza. | 6 Months | |
Secondary | Number of Days of Usual Activity (i.e. Job, School,Household/Family/Community Activities) Lost Due to Influenza Disease, All Subjects | The number of subjects in this analysis included all subjects in the per protocol efficacy population. | 6 Months | |
Secondary | Number of Days of Usual Activity (i.e. Job, School,Household/Family/Community Activities) Lost, Subset of Subjects With Virus-Confirmed-Influenza | The analysis was done among the subset of subjects in the per protocol efficacy population who had culture-confirmed influenza. | 6 Months | |
Secondary | Percentages of Subjects Who Achieved HI Titers =40 After One Vaccination of Either Cell-culture Derived or Egg-derived Influenza Vaccine or Placebo | Immunogenicity was measured as the percentage of subjects achieving HI titers =40 at baseline (day 1) and three weeks after (day 22) one vaccination of either cell-culture or egg-derived vaccine or placebo for each of the three influenza vaccine strains (A/H1N1, A/H3N2 and B), evaluated using hemagglutination inhibition (HI) egg-derived antigen assay. This criterion is met according to US (CBER) guideline if the lower limit of the two-sided 95% CI for the percentage of subjects achieving HI titers =40 is =70%. | Before vaccination (day 1) and three weeks after vaccination (day 22) | |
Secondary | Percentages of Subjects Achieving Seroconversion After One Vaccination of Either Cell-culture Derived or Egg-derived Influenza Vaccine or Placebo | As per the CBER guideline, seroconversion is defined as the percentage of subjects with a prevaccination HI titer <10, a postvaccination titer =40; or in subjects with prevaccination HI titer =10, a =4-fold increase in postvaccination HI antibody titer. According to CBER criteria, the lower limit of the two-sided 95% CI for the percentage of subjects achieving seroconversion for HI antibody titer at day 22 met exceeded 40%. | Three weeks after vaccination (day 22) | |
Secondary | Number of Subjects Reported Solicited Local and Systemic Reactions up to 7 Days After Vaccination | The solicited local and systemic reactogenicity were collected up to 7 days after vaccination for all three vaccine groups. | Up to 7 days post vaccination |
