Immunogenicity and Safety of a Single 0.5 mL Dose of Inflexal V With a 0.25 mL 2-dose Regimen of Inflexal V
A Phase III Open, Randomized, Parallel, Multi-center Study in Children Aged 6 - 35 Months to Compare the Immunogenicity and Safety of a Single 0.5 mL Dose of Inflexal V With a 0.25 mL 2-dose Regimen of Inflexal V Administered According to a 0/4 Week Schedule

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.

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
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
Study Arms (2)
Inflexal V 0.25 mL x 2
ACTIVE COMPARATORInflexal V 0.5 mL x 1
EXPERIMENTALInterventions
vaccination with Inflexal V 0.25 mL administered twice, 4 weeks apart
