Outcomes

Primary Outcome Measures

Immunogenicity endpoint: Seroprotection rate
Seroprotection rate is defined as the proportion of subjects with HAI titer ≥ 1:40.
Immunogenicity endpoint: Seroconversion rate
The seroconversion is defined as the HAI titer of the post-vaccination serum is at least 1:40 for those who had a negative pre-vaccination HAI serum titer or a four-fold or greater increase in HAI titers in subjects who had a positive pre-vaccination HAI serum titer. The seropositive is defined as the HAI titer ≥ 1:10, and the seronegative is defined as HAI titer < 1:10.
Immunogenicity endpoint: Geometric mean folds increase in HAI titer

Secondary Outcome Measures

Safety: Reactogenicity events
Reactogenicity events are pre-specified adverse events systematically recorded for 7 days after vaccination. The selection of the events to be collected systematically is based on events expected to occur with wild-type influenza infection including fever (≥38°C), runny nose or nasal congestion, cough, sore throat, headache, muscle aches, vomiting, nausea and malaise. Furthermore, the local (injection site) reactions will also be evaluated that include soreness/pain, swelling, redness, ecchymosis and limitation of arm motion.
Safety: Serious and non-serious adverse events

5. Study Description

Brief Summary
The purpose of this study is to evaluate the antibody response to each of the three influenza vaccine strains included in the licensed seasonal flu vaccine, as measured by hemagglutination inhibition (HAI) at three weeks post immunization in non-elderly and elderly subjects in compliance with the requirements of the current European Union (EU) recommendations for the evaluation of the immunogenicity for a new formulation of a licensed flu vaccine (CPMP/BWP/214/96).
