Outcome Measures

Primary Outcomes (1)

Immunogenicity Endpoint: hemagglutination inhibition (HAI) titer and microneutralization (MN) titer
The primary immune response endpoint is to evaluate the seroconversion rate (SCR) in terms of HAI assays at Day 43 (21 days after the second dose).The secondary HAI endpoints are defined as following: 1. SCR for the first vaccination, at Day 22. 2. Seroprotection rates (SPR) for each vaccination, at Day 22 and 43. 3. The geometric mean fold rise (GMFR) for each vaccination, at Day 22 and 43. The supportive immunogenicity endpoints of MN antibodies are SCRs, SPRs and GMFRs at Day 22 and 43.
At Day 43 (21 days after the second dose).

Secondary Outcomes (1)

The secondary objective is to evaluate the safety and tolerability profiles including the presence or absence of the pre-specified reactogenicity events and other serious/non-serious adverse events after vaccination.
At 4 weeks after two doses of study vaccine, 4 weeks apart. Reactogenicity will be recorded for 7 days after each vaccination.

Primary Completion

You may not qualify if:

Medical history of physician-confirmed infection with an H5N1 virus or a history of vaccination with an H5N1 influenza vaccine.
Subject is at high risk of contracting H5N1 influenza infection (e.g. poultry workers).
Has received any other licensed vaccines within 2 weeks for inactivated vaccines or 4 weeks for live vaccines prior to enrollment in this study.
Use of any investigational or non-registered product other than the study vaccine within 30 days preceding the first dose of study vaccine, or planned use during the study period.
Subject has used oral or parenteral steroids, high-dose inhaled steroids (\>800 mcg/day of beclomethasone dipropionate or equivalent) or other immunosuppressive or cytotoxic drugs within 30 days preceding the first dose of study vaccine.
Subject has received a blood transfusion or immunoglobulins within 90 days prior to first dose of study vaccine, or planned administration of any blood products during the study period.
Subject has a known allergy to eggs or other components of the study vaccine.
Subject has a history of severe allergic reactions or anaphylaxis.
Subject has a history of Guillain-Barré Syndrome.
Subject has an acute illness or temperature greater than 38.0 degrees Celsius by any method within 3 days prior to each vaccination.
Subject has confirmed or suspected immunosuppressive or immunodeficient condition including history of human immunodeficiency virus (HIV) infection.
Subject has a rash, dermatologic condition or tattoos which may interfere with injection site reaction rating.
Evidence of substance (alcohol or drug) abuse or of neurological or psychiatric diagnoses which, even if clinically stable, are deemed by the investigator to render the potential subject unable/unlikely to provide accurate safety reports.
Subjects with abnormal laboratory results at screening:(1) ALT or AST \> or = 1 x upper limit of normal (ULN). (2) Creatinine \> or = 1 x ULN. (3) Any significant laboratory abnormality as judged by the investigator
Females are known pregnancy or a positive urine beta-human chorionic gonadotropin test result prior to the first study vaccine dose, or are lactating or nursing.
