NCT01229397

Brief Summary

The study aims to evaluate the immunogenicity of a single full (0.5 mL) dose and a 0.25 mL 2-dose regime of Inflexal V in unprimed children aged 6 - \<36 months, using the EMA guideline for the re-registration of the seasonal influenza vaccine in adults (aged ≥18 ≤60 years) as reference.

Outcome Measures

Primary Outcomes (3)

  • Immunogenicity of a Single Full (0.5 mL) Dose and a 0.25 mL 2-dose Regimen of Inflexal V, Using the EMA Guideline for the Re-registration of the Seasonal Influenza Vaccine in Adults (Aged ≥18 to ≤60 Years) as Reference

    Seroprotection rate

    This assesment was done for immunogenicity data collected at Day 29 after completion of designated vaccination regimen

  • Immunogenicity of a Single Full (0.5 mL) Dose and a 0.25 mL 2-dose Regimen of Inflexal V, Using the EMA Guideline for the Re-registration of the Seasonal Influenza Vaccine in Adults (Aged ≥18 to ≤60 Years) as Reference

    Seroconversion rate

    This assesment was done for immunogenicity data collected at Day 29 after completion of designated vaccination regimen

  • Immunogenicity of a Single Full (0.5 mL) Dose and a 0.25 mL 2-dose Regimen of Inflexal V, Using the EMA Guideline for the Re-registration of the Seasonal Influenza Vaccine in Adults (Aged ≥18 to ≤60 Years) as Reference

    GMT-fold increase - calculated as the GMT on Day 22 divided by the baseline GMT value

    This assesment was done for immunogenicity data collected at Day 29 after completion of designated vaccination regimen

Secondary Outcomes (1)

  • Number of Participants With Local and Systemic Adverse Events as a Measure of Safety and Tolerability

    Solicited local and systemic AEs were collected from Day 1 (day of vaccination) to Day 4 inclusive using a subject diary
