This exception includes monovalent pandemic influenza vaccines and multivalent influenza vaccines * Receipt of immune globulins, blood or blood-derived products in the past 3 months * Receipt of oral or injectable antibiotic therapy within 72 hours prior to the first blood draw * Participation at the time of study enrollment (or in the 4 weeks preceding the trial vaccination) or planned participation during the present trial period in another clinical trial investigating a vaccine, drug, medical device, or medical procedure * 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) on the day of vaccination or febrile illness (temperature ≥ 38.0°C). A prospective participant should not be included in the study until the condition has resolved or the febrile event has subsided * Deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized involuntarily * Identified as a natural or adopted child of the Investigator or employee with direct involvement in the proposed study * The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.
