  • Previous vaccination against influenza (in the previous 6 months) with either the trial vaccine or another vaccine.
  • Receipt of immune globulins, blood or blood-derived products in the past 3 months.
  • Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy, within the preceding 6 months; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months).
  • Known systemic hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to the vaccines used in the trial or to a vaccine containing any of the same substances.
  • Thrombocytopenia or bleeding disorder, contraindicating IM vaccination based on Investigator's judgement.
  • Alcohol or substance abuse that, in the opinion of the Investigator might interfere with the trial conduct or completion.
  • Chronic illness that, in the opinion of the Investigator, is at a stage where it might interfere with trial conduct or completion
  • Moderate or severe acute illness/infection (according to Investigator judgment) or febrile illness (temperature greater than or equal to (\>=) 38.0 degree Celsius) on the day of vaccination. A prospective participant should not be included in the study until the condition had resolved or the febrile event had subsided.
  • Identified as an Investigator or employee of the Investigator or study center with direct involvement in the proposed study, or identified as an immediate family member (ie, parent, spouse, natural or adopted child) of the Investigator or employee with direct involvement in the proposed study.
  • Personal or family history of Guillain Barré syndrome.
