Imovax® Rabies and VERORAB® Immunogenicity and Safety After One Week 2-sites Intradermal or 1-site Intramuscular Pre-Exposure Prophylaxis Regimens, Followed by a Simulated Post-Exposure Prophylaxis Regimen at One Year

The primary objective of the study is to demonstrate that a short intramuscular (IM) pre-exposure prophylaxis (PrEP) regimen is non-inferior to the reference IM PrEP regimen in terms of seroconversion rate.

The secondary objectives of the study are:

* To describe the immunogenicity of the PrEP regimen in each group
* To describe the antibody persistence in each group 6 months and 1 year after the last PrEP vaccination
* To describe the immunogenicity of the simulated post-exposure prophylaxis (PEP) regimen in each group
* To describe the safety profile of study vaccines administered as PrEP regimen and as a simulated PEP regimen in each group

Study duration per participant is approximately 403 to 436 days

Eligibility Criteria:
Inclusion criteria :

* Aged ≥ 2 years on the day of inclusion
* Participant aged \< 18 years: Assent form has been signed and dated by the subject (as appropriate, according to country-specific institution requirements), and informed consent form (ICF) signed and dated by the parent or another legally acceptable representative
* Participant aged ≥ 18 years: ICF signed and dated by the subject
* The participant (and parent/legally acceptable representative, if applicable) is able to attend all scheduled visits and to comply with all trial procedures

Exclusion criteria:

* Participant is 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 pre-menarche or post-menopausal for at least 1 year, or surgically sterile.
* Participation at the time of study enrollment (or in the 4 weeks preceding the first trial vaccination) 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 preceding the first trial vaccination or planned receipt of any vaccine in the 4 weeks following any trial vaccination except for influenza vaccination, which may be received at least 2 weeks before study vaccines. This exception includes monovalent pandemic influenza vaccines and multivalent influenza vaccines.
* Previous vaccination at any time against rabies 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
* Self-reported thrombocytopenia, contraindicating IM vaccination
* Bleeding disorder or receipt of anticoagulants in the 3 weeks preceding inclusion, contraindicating intramuscular 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, 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 subject should not be included in the study until the condition has resolved or the febrile event has 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
* Receipt of chloroquine or other medications used for malaria chemoprophylaxis, with or without other anti-malarial treatment, for more than 4 weeks (duration of anti-malarial course) and part of the treatment received within the 2 weeks before vaccination, contraindicating intradermal vaccination
