Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Subjects who the investigator believes that their parent(s)/Legally Acceptable Representative(s) (LAR) can and will comply with the requirements of the protocol. A male or female child between, and including, 5 and 17 months of age at the time of the first vaccination. Signed or thumb-printed informed consent obtained from the parent(s)/LAR(s) of the child. Where parent(s)/LAR(s) are illiterate, the consent form will be countersigned by a witness. Healthy subjects as established by medical history and clinical examination before entering into the study. Subjects who have received three documented doses of hepatitis B vaccine. Exclusion Criteria: Same sex twins. Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination. Family history of congenital or hereditary immunodeficiency. History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine. Major congenital defects or serious chronic illness. History of any neurological disorders or seizures. Moderate or severe malnutrition at screening defined as weight for age Z-score less than 2. Acute disease and/or fever at the time of enrolment Acute or chronic, clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by physical examination or medical history. Use of a drug or vaccine that is not approved for that indication other than the study vaccines within 30 days preceding the first dose of study vaccine, or planned use during the study period. Chronic administration of immunosuppressants or other immune-modifying drugs since birth. Planned administration/administration of a licensed vaccine not foreseen by the study protocol within 7 days of the first dose of study vaccine. Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational product. Administration of immunoglobulins and/or any blood products within 1 month preceding the first dose of study vaccine or planned administration during the study period. Child in care. Any other findings that the investigator feels would increase the risk of having an adverse outcome from participation in the trial.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Anti-Circumsporozoite (Anti-CS) Antibody Titers | Antibody titers are presented as geometric mean titers (GMTs) and are measured in titers. | One month post-dose 3 (Month 3) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Anti-hepatitis B (Anti-HB) Antibody Concentrations | Antibody concentrations are presented as geometric mean concentrations (GMCs) and expressed in milli-international units per milliliter (mIU/mL). | One month post-dose 3 (Month 3) | 
| Number of Subjects With Any and Grade 3 Solicited Local Symptoms | Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal activity. Grade 3 redness/swelling = redness/swelling spreading beyond 20 millimeters (mm) of injection site. | Over a 7-day (Days 0-6)post-vaccination period after each dose and across doses | 
| Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms | Assessed solicited general symptoms were drowsiness, irritability, loss of appetite, fever [defined as axillary temperature equal to or above (≥) 37.5 degrees Celsius (°C)]. Any = occurrence of the symptom regardless of intensity grade or relationship to vaccination. Grade 3 loss of appetite = not eating at all. Grade 3 irritability = crying that could not be comforted/prevented normal activity. Grade 3 drowsiness = drowsiness that prevented normal activity. Grade 3 fever = fever higher than (>) 39.0 °C. Related = symptom assessed by the investigator as related to the vaccination. | Over a 7-day (Days 0-6) post-vaccination period after each dose and across doses | 
| Number of Subjects With Unsolicited Adverse Events | An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination. | Within the 30-day (Days 0-29) post-vaccination period | 
| Number of Subjects With Serious Adverse Events | Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity. | Up to 8 months post-dose 1 |
