Inclusion Criteria: All subjects must satisfy ALL the following criteria at study entry: A male or female infant aged between 8 and 12 weeks inclusive at the time of first vaccination Signed or thumb-printed informed consent obtained from the parent(s)/Legally Acceptable Representative [LAR(s)] of the child. Where parent(s)/LAR(s) are illiterate, the consent form will be countersigned by an independent witness Subjects who the investigator believes that their parent(s)/LAR(s) can and will comply with the requirements of the protocol Healthy subjects as established by medical history and clinical examination before entering into the study Born to a mother who is Hepatitis B surface antigen (HBsAg) negative Born to a mother who is Human Immunodeficiency Virus (HIV) negative Born after a normal gestation period of 36 to 42 weeks inclusive. Exclusion Criteria: The following criteria should be checked at the time of study entry. If ANY exclusion criterion applies, the subject must not be included in the study: Child in care Acute disease and/or fever at the time of enrolment Serious acute or chronic illness determined by clinical or physical examination and laboratory screening tests Laboratory screening tests out of range Previous vaccination with diphtheria, tetanus, pertussis, Haemophilus influenzae type b, Streptococcus pneumoniae, hepatitis B vaccine or rotavirus vaccines. Planned administration/administration of a licensed vaccine not foreseen by the study protocol within 7 days of the first dose of study vaccine. 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. Administration of immunoglobulins and/or any blood products in the period between birth and Dose 1 and within the three months preceding planned vaccine administration during the study period. Chronic administration of immunosuppressants or other immune-modifying drugs in the period between birth and Dose 1. 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. Same sex twin Maternal death History of allergic reactions or anaphylaxis to previous immunizations. History of allergic disease or reactions likely to be exacerbated by any component of the vaccine. Any other findings that the investigator feels would increase the risk of having an adverse outcome from participation in the trial. Any other findings that the investigator feels would result in data collected being incomplete or of poor quality. Previous participation in any other malaria vaccine trial.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Seroprotected Subjects Against Anti-Hepatitis B (HBs) Antigen | A seroprotected subject was defined as a subject with anti-HBs antibody titers greater than or equal to (>=) the cut-off of 10 mili-international units per mililiter (mIU/mL). A decrease in the specificity of the anti-HBs ELISA assay had been observed in some studies for low levels of antibody (10-100 mIU/mL). The table shows updated results following partial or complete retesting/reanalysis, with study groups pooled by primary vaccine administered (RTS,S vs Engerix -B). | At Month 3, aka at one month post Dose 3 of RTS,S vaccine or Engerix-B | 
| Anti-Hepatitis B (HBs) Antibody Concentrations for RTS,S Group and Engerix B Group | Concentrations, by enzyme-linked immunosorbent assay (ELISA), were presented as geometric mean concentrations (GMCs), and expressed in milli-international units per milliliter (mIU/mL). The assay cut-off was the seropositivity cut-off value of greater than or equal to (>=) 10 mIU/mL. A decrease in the specificity of the anti-HBs ELISA assay had been observed in some studies for low levels of antibody (10-100 mIU/mL).
