Timeframe: During the entire study period (Day 0 - Day 20 after vaccination).
- Subjects who the investigator believes that they can and will comply with the requirements of the protocol.
 - Written informed consent obtained from the subject
 
- 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.
 
- 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
 
Subjects who the investigator believes that they can and will comply with the requirements of the protocol.
- 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.

 - 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.
