• Informed consent form had been signed and dated.
• Able to attend all scheduled visits and to complied with all trial procedures.

You may not qualify if…

• An individual fulfilling any of the following criteria was to be excluded from trial enrollment:
• Participant was pregnant, or lactating, or of childbearing potential and not using an effective method of contraception or abstinence from at least 4 weeks prior to the first vaccination until at least 4 weeks after the last vaccination. To be considered of non-childbearing potential, a female must be post-menopausal for at least 1 year, or surgically sterile.
• Participation at the time of study enrollment or, planned participation during the present trial period in another clinical trial investigating a vaccine, drug, medical device, or medical procedure.
• Receipt of any vaccine in the 4 weeks (28 days) preceding the first trial vaccination or planned receipt of any vaccine prior to Visit 6.
• Previous vaccination against rabies (in pre- or post-exposure regimen) 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).
• At high risk for rabies infection during the trial (e.g., veterinarians and staff, animal handlers, rabies researchers, or any others whose activities may bring them into frequent contact with rabies virus or animals who had the rabies virus).
• Known systemic hypersensitivity to any of the vaccine or human rabies immunoglobulins (HRIG) 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.
• Self-reported thrombocytopenia, contraindicating IM vaccination.
• Bleeding disorder, or receipt of anticoagulants in the 3 weeks preceding inclusion, contraindicating IM vaccination.
• Deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized involuntarily.
• Current alcohol abuse or drug addiction.
• Chronic illness that, in the opinion of the investigator, was at a stage where it might interfere with trial conduct or completion (e.g., cardiac disorders, renal disorders, auto immune disorders, diabetes, psychiatric disorders or chronic infection).
• Moderate or severe acute illness/infection (according to investigator judgment) on the day of vaccination or febrile illness (temperature greater than or equal to [>=] 100.4 Fahrenheit >=38.0 Celsius). 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 (i.e., parent, spouse, natural or adopted child) of the Investigator or employee with direct involvement in the proposed study.
• History of Guillain-Barré syndrome.
