A subject who is considered by the investigator to be at risk of pregnancy must also have a negative urine pregnancy test at screening and, if screening and Day 0 do not occur on the same day, on the day of vaccination prior to randomization. Investigator judgment is required to assess each subject's need for pregnancy testing. 8.

Exclusion Criteria: 1. Subjects who were previously administered influenza vaccine in 2014-2015 influenza season 2. Previous randomisation in the present study 3. Participation in another clinical study with an investigational product during the last 3 month 4. Acute illness or evidence of significant active infection at randomization; 5. Fever =99.5°F (37.5°C) at randomization; 6. Any drug therapy from 15 days prior to randomization or expected drug therapy through 28 days post last dose with the exception of the following classes/types of medications, which are allowed: Contraceptives (change in contraceptive type or method is acceptable as long as guidelines are followed for prevention of pregnancy during change); Topical corticosteroids, calcineurin inhibitors, or antifungals for uncomplicated dermatitis; Chronic medications (including those taken on an as-needed basis) that have been well tolerated and were not initiated and/or did not have a dosage change within 90 days prior to randomization. 7.

Any known immunosuppressive condition or immune deficiency disease including known or suspected infection with human immunodeficiency virus (HIV); 9. History of allergic disease or reactions likely to be exacerbated by any component of the investigational product including allergy to eggs, egg proteins, gentamicin, or gelatin or serious, life threatening, or severe reactions to previous influenza vaccinations; 10. Use of aspirin or salicylate-containing medications within 28 days prior to randomization or expected receipt through the entire study; 11. History of Guillain-Barré syndrome; 12. Use of antiviral agents with activity against influenza virus (including amantadine, rimantadine, oseltamivir, and zanamivir) within 28 days prior to first dose of investigational product or anticipated use of such agents in the study period; 13. Administration of any live virus vaccine within 30 days prior to enrolment, or if receipt of another live virus vaccine is expected within 30 days of any study vaccination; 14. Administration of any inactivated vaccine within 14 days prior to enrolment or if receipt of another inactivated vaccine is expected within 14 days of any study vaccination; 15.
