Laboratory-confirmed or suspected influenza disease within 6 months prior to Visit 1. "Laboratory-confirmed" includes:

Positive serology result

Positive rapid antigen test
"Suspected" influenza disease includes: subjects with influenza-like illness within the past 6 months with a household/intimate contact with "laboratory-confirmed" influenza disease
- Individuals experiencing any acute disease or infection requiring systemic antibiotic or antiviral therapy within 6 days before vaccination (chronic antibiotic therapy for urinary tract prophylaxis is acceptable)
- History of any anaphylaxis, serious vaccine reactions, or hypersensitivity to influenza viral proteins, to any excipients, and to eggs (including ovalbumin), chicken protein.
- History of any serious disease, such as:

a. Medically significant cancer (except for benign or localized skin cancer, cancer in remission for ≥10 years or localized prostate cancer that has been clinically stable for more than 2 years without treatment) b. autoimmune disease (including rheumatoid arthritis) except for Hashimoto's thyroiditis that has been clinically stable for ≥ 5 years; c. diabetes mellitus type I; d. poorly controlled diabetes mellitus type II; e. diabetes relating to genetic defects/syndromes, diseases of the exocrine pancreas, or infections; f. advanced arteriosclerotic disease; g. severe chronic obstructive pulmonary disease (COPD), i.e. GOLD stages 3 and 4; h. acute or progressive hepatic disease; i. acute or progressive renal disease; j. medically significant congestive heart failure; k. history of underlying medical condition such as major congenital abnormalities requiring surgery, chronic treatment, or associated with developmental delay (e.g., Down's syndrome)

Known or suspected impairment/alteration of immune function, including:
1. Receipt of immunosuppressive therapy such as oral or systemic corticosteroids, (use of inhaled, intranasal, or topical corticosteroids is allowed) or cancer chemotherapy within 60 days prior to Visit 1
2. receipt of immunostimulants within 60 days prior to Visit 1
3. receipt of parenteral immunoglobulin preparation, blood products, and/or plasma derivates within 3 months prior to Visit 1 or planned during the full length of the study
4. HIV infection or HIV-related disease
5. Heritable immunodeficiency
6. Abnormalities of splenic or thymic function

Experienced body temperature ≥38.0°C (100.4°F) within 3 days prior to each study vaccination.
Use of antipyretic/analgesic medication within 24 hours of each study vaccination

Pregnant or breast-feeding female
Any positive or indeterminate pregnancy test
If female, of childbearing potential, and has not used any of the "acceptable contraceptive methods" for at least 2 months prior to study entry
1. Of childbearing potential is defined as status post onset of menarche and not surgically sterile
2. Acceptable birth control methods are defined as one or more of the following:

Barrier (condom with spermicide or diaphragm with spermicide) each and every time during intercourse iii. Intrauterine device (IUD) iv. Monogamous relationship with vasectomized partner. Partner must have been vasectomized for at least six months prior to the subject's study entry
If female of childbearing potential, refusal to use an "acceptable contraceptive method" during the study including day 43.
If female of childbearing potential, refusal to submit for pregnancy testing prior to study vaccination
