Overview
This Phase 3 study is a randomized, observer-blind study of MF59-adjuvanted influenza vaccine (aQIV or aTIV) compared with a non-adjuvanted influenza vaccine (QIV or TIV) in adults ≥65 years of age. The aim of the study is to evaluate MF59-adjuvanted influenza vaccine compared with non-adjuvanted influenza vaccine in the prevention of reverse transcription-polymerase chain reaction (RT-PCR)-confirmed influenza A and/or B in subjects ≥65 years of age.

6. Clinical conditions representing a contra-indication to intramuscular administration of vaccines or blood draw.
7. Abnormal function of the immune system resulting from:
1. Clinical conditions;
2. Systemic administration of corticosteroids (PO/IV/IM) at a dose ≥20 mg/day of prednisone (or equivalent) for more than 14 consecutive days within 90 days prior to informed consent; Topical, inhaled and intranasal corticosteroids are permitted. Intermittent use (one dose in 30 days) of intra-articular corticosteroids are also permitted;
3. Administration of antineoplastic and immunomodulating agents or radiotherapy within 90 days prior to informed consent.
8. Receipt of immunoglobulins or any blood products within 180 days prior to informed consent.
9. Receipt of any investigational or non-registered product (drug or vaccine) other than the study vaccine within 30 days preceding the study vaccination, or planned use during the entire study period.
10. Acute (severe) febrile illness.
11. Any other clinical condition that, in the opinion of the investigator, might interfere with the results of the study or pose additional risk to the subject due to participation in the study.
