Key Inclusion and Exlusion Criteria (CT)

Inclusion:

1) Aged ≥ 2 years* on the day of inclusion

2) Subject 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

Subject aged ≥ 18 years: ICF signed and dated by the subject

3) The subject (and parent/legally acceptable representative, if applicable)

is able to attend all scheduled visits and to comply with all trial

Exclusion:

1) Subject 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.

2) 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.

3) 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.

4) Previous vaccination at any time against rabies with either the trial

vaccine or another vaccine

5) Receipt of immune globulins, blood, or blood-derived products in the

past 3 months

6) 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)

7) 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

8) Self-reported thrombocytopenia, contraindicating IM vaccination

9) Bleeding disorder or receipt of anticoagulants in the 3 weeks preceding

inclusion, contraindicating intramuscular vaccination

10) Deprived of freedom by an administrative or court order, or in an

emergency setting, or hospitalized involuntarily

11) Current alcohol abuse or drug addiction

12) Chronic illness that, in the opinion of the investigator, is at a stage

where it might interfere with trial conduct or completion

13) 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

14) 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

15) History of Guillain-Barré syndrome

16) 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
