Eligibility Criteria
Inclusion
- Participants' parent(s)/LAR(s) who, in the opinion of the investigator, can and will comply with the requirements of the protocol (e.g. return for follow-up visits).
- Signed or thumb-printed and witnessed informed consent obtained from the parent(s)/LAR(s) of the participant prior to performance of any study specific procedure. Where parent(s)/LAR(s) are illiterate, the consent form will be countersigned by an independent witness.
- A male or female between, and including, five and 17 months of age at the time of the first vaccination.
- Healthy participants as established by medical history and clinical examination before entering into the study.
- Previously received three documented doses of diphtheria, tetanus, pertussis, hepatitis B vaccine (DTPHepB), and at least three doses of oral polio vaccine.
Exclusion
- Child in care.
- Use of a drug or vaccine that is not approved for that indication (by one of the following regulatory authorities: Food and Drug Administration \[FDA; USA\] or European Union member state or WHO \[with respect to prequalification\]) other than the study vaccines during the period starting 30 days before the first dose of study vaccines (Day -29 to Day 0), or planned use during the study period.
- Any medical condition that in the judgment of the investigator would make intramuscular injection unsafe.
- Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs during the period starting six months prior to the first vaccine dose. For corticosteroids, this will mean prednisone (0.5 mg/kg/day (for pediatric participants) or equivalent. Inhaled and topical steroids are allowed.
- Planned administration/administration of a vaccine not foreseen by the study protocol in the period starting seven days before each dose and ending seven days after each dose of vaccine administration.
- Concurrently participating in another clinical study, at any time during the study period, in which the participant has been or will be exposed to an investigational or a non-investigational vaccine/product (pharmaceutical product or device).
- Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination (no laboratory testing required).
- Family history of congenital or hereditary immunodeficiency.
- History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccines.
- History of anaphylaxis post-vaccination.
- History of any, or documented, serious adverse reaction to rabies vaccination.
- Contraindication to rabies vaccination (Rabipur is contraindicated in participants with history of a severe hypersensitivity to any of the ingredients in the vaccine. Note that the vaccine contains polygeline and residues of chicken proteins, and may contain traces of neomycin, chlortetracycline and amphotericin B).
- Major congenital defects.
- Serious chronic illness.
- Children with a past history of a neurological disorder or atypical febrile seizure (a febrile seizure is atypical if it meets one of the following criteria: not associated with fever; lasts \> 5 minutes; focal (not generalized); followed by transient or persistent neurological abnormality; occurs in a child \< 6 months of age).
- Acute disease and/or fever at the time of enrolment. Fever is defined as temperature ≥ 37.5°C/99.5°F for oral, axillary or tympanic route, or ≥ 38.0°C/100.4°F for rectal route.
- Participants with a minor illness (such as mild diarrhea, mild upper respiratory infection) without fever may, be enrolled at the discretion of the investigator.
- Administration of immunoglobulins and/or any blood products during the period starting three months before the first dose of study vaccine or planned administration during the study period.
- Moderate or severe malnutrition at screening defined as weight for age or weight for height Z-score \< -2.
- Hemoglobin concentration \< 8 g/dl at screening.
- Same sex twins (to avoid misidentification).
- Maternal death.
- Prior receipt of an investigational malaria vaccine.
