Brief summary: This study is designed to test the immunogenicity and reactogenicity of the Fluarix™/Influsplit SSW® influenza vaccine containing the influenza strains recommended for the 2008-2009 season.


Eligibility criteria: Inclusion Criteria:

* Subjects who the investigator believes that they can and will comply with the requirements of the protocol should be enrolled in the study.
* A male or female aged 18 years or above at the time of the vaccination.
* Written informed consent obtained from the subject.
* Healthy subjects or with well-controlled chronic diseases as established by medical history and clinical examination before entering into the study.
* If the subject is female, she must be of non-childbearing potential or if she is of childbearing potential, she must practice adequate contraception for 30 days prior to vaccination, have a negative pregnancy test and continue such precautions for 2 months after completion of the vaccination series

Exclusion Criteria:

* Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine(s) within 30 days preceding the vaccination or planned use during the study period.
* Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs within six months prior to the vaccine dose.
* Administration of immunoglobulins and/or any blood products within the three months preceding the administration of the study vaccine or planned during the study.
* Administration of an influenza vaccine within 1 year preceding the study start.
* Administration of an influenza vaccine other than the study vaccine during the entire study
* Clinically or virologically confirmed influenza infection within 1 year preceding the study start
* History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.
* Acute disease at the time of enrolment.
* Acute clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by physical examination or laboratory screening tests.
* Not stabilized or clinically serious chronic underlying disease.
* Lactating female.
* History of chronic alcohol consumption and/or drug abuse.
* Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
* Any condition which, in the opinion of the investigator, prevents the subject from participation in the study
