Eligibility Criteria:
Inclusion Criteria:

* Subjects who the investigator believes that they can and will comply with the requirements of the protocol.
* Written informed consent obtained from the subject
* Male and female adults, 18 years of age and older in stable health as determined by investigator's clinical examination and assessment of subjects' medical history.
* 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:

* 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.
* 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.
* Acute disease and/or fever at the time of enrolment.
* Significant acute or chronic, uncontrolled medical or psychiatric illness.
* Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
* Acute, clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, based on history and physical examination.
* 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 study vaccine dose.
* A history of any demyelinating disease including Multiple Sclerosis and Guillain-Barré syndrome.
* Presence of an active neurological disorder.
* 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 anti-platelet 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 FLU-Q-QIV 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.
