Eligibility

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Subjects who, in the opinion of the investigator, can and will comply with the

requirements of the protocol.

- A male or female 18 years of age and older at the time of the first vaccination.

- Written informed consent obtained from the subject.

- Healthy subjects as established by medical history and clinical examination before

entering into the study.

- Female subjects of non-childbearing potential may be enrolled in the study.

- Female subjects of childbearing potential may be enrolled in the study, if the

subject:

- has practiced adequate contraception for 30 days prior to vaccination, and

- has a negative pregnancy test on the day of vaccination, and

- has agreed to continue adequate contraception during the entire treatment period

and for 2 months after completion of the vaccination. Exclusion Criteria:

- Use of any investigational or non-registered product (drug or vaccine) other than the

study vaccine within 30 days preceding the dose of study vaccine, or planned use during the study period.

- Administration of any influenza vaccine within 6 months preceding the study start or

planned use of such vaccines during the study period.

- Administration of any other vaccine(s) within 30 days prior to study enrolment or

during the study period.

- Clinically or virologically confirmed influenza infection within the six months

preceding the study vaccination.

- Acute disease and/or fever at the time of enrolment.

- Significant acute or chronic, uncontrolled medical or psychiatric or neurological

illness.

- Any confirmed or suspected immunosuppressive or immunodeficient condition.

- Acute or chronic, clinically significant pulmonary, cardiovascular, hepatic or renal

functional abnormality, as determined by physical examination or laboratory screening tests.

- Insulin-dependent diabetes mellitus.

- Presence of blood dyscrasias, including hemoglobinopathies and myelo- or

lymphoproliferative disorder.

- Chronic administration of immunosuppressants or other immune-modifying drugs within

six months prior to the vaccine dose.

- A history of any demyelinating disease including Multiple Sclerosis and

Guillain-Barré syndrome.

- History of chronic alcohol abuse and/or drug abuse as deemed by the investigator to

render the potential subject unable/unlikely to provide accurate safety reports.

- Any significant disorder of coagulation that increases the risk of intramuscular

injections or treatment with coumadin derivatives or heparin. Persons receiving prophylactic antiplatelet medications, e. g. low-dose aspirin, and without a clinically-apparent bleeding tendency are eligible.

- Administration of immunoglobulins and/or any blood products within the three months

preceding the administration of the study vaccine or planned during the study.

- Any known or suspected allergy to any constituent of Fluviral® and/or a history of

anaphylactic type reaction to consumption of eggs, and/or reactions to products containing mercury.

- A history of severe adverse reaction to a previous influenza vaccination.

- Pregnant and/or lactating/nursing female.

- Any condition which, in the opinion of the investigator, prevents the subject from

participation in the study.
