Exclusion criteria: * Participation at the time of study enrollment (or in the 4 weeks preceding the first study vaccination) or planned participation during the present study period in another clinical study investigating a vaccine, drug, medical device, or medical procedure. * For all participants: Receipt of any vaccine in the 30 days preceding the first study vaccination. For participants in immunogenicity subset: Planned receipt of any vaccine before Visit 2 for participants receiving 1 dose of influenza vaccine or Visit 3 for participants receiving 2 doses of influenza vaccine. * Previous vaccination against influenza in the preceding 6 months with either the study vaccine or another influenza vaccine * Receipt of immune globulins, blood or blood-derived products in the past 3 months. * Known or suspected congenital or acquired immunodeficiency (eg, HIV); 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 study or to a vaccine containing any of the same substances. Exception: participants with an egg allergy are allowed to enroll in the study. * Thrombocytopenia, bleeding disorder, or receipt of anticoagulants that based on Investigator's judgment contraindicate intramuscular vaccination * Chronic illness that, in the opinion of the investigator, was at a stage where it might interfere with study conduct or completion. * Moderate or severe acute illness/infection (according to investigator judgment) on the day of vaccination or febrile illness (temperature ≥ 38.0 C \[≥ 100.4 F\]).
