Eligibility Criteria:
Inclusion Criteria:~* Subjects who, in the opinion of the investigator, can and will comply with the requirements of the protocol.~* Written informed consent obtained from the subject prior to performing of any study specific procedure.~* A male or female between, and including, 18 and 55 years of age at the time of enrolment.~* Healthy subjects as established by medical history and clinical examination before entering into the study.~* Available to participate for the duration of the study.~* Female subjects of non-childbearing potential may be enrolled in the study.~  - Non-childbearing potential is defined as pre-menarche, current tubal ligation, hysterectomy, ovariectomy or post-menopause.~* Female subjects of childbearing potential may be enrolled in the study, if the subject:~  * has practiced adequate contraception for 30 days prior to vaccination, and~ * has a negative pregnancy test at enrolment, and~ * has agreed to continue adequate contraception during the entire treatment period and for two months after completion of the vaccination series and/or malaria challenge.~Exclusion Criteria:~* Use of any investigational or non-registered product (drug or vaccine) 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 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 ≥ 20 mg/day, or equivalent. Inhaled and topical steroids are allowed.~* Administration of long-acting immune-modifying drugs at any time during the study period.~* Chronic use of antibiotics with antimalarial effects.~* Planned administration/administration of a vaccine not foreseen by the study protocol in the period starting seven days before the first dose.~* 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 vaccine/product.~* Seropositive for hepatitis B surface antigen (HBsAg) or hepatitis C virus (HCV).~* Documented HIV-positive subject.~* Previous vaccination against malaria.~* History of malaria chemoprophylaxis within 60 days prior to vaccination.~* Any history of malaria (for the vaccine groups).~* Planned travel to malaria endemic areas during the study period.~* History of splenectomy.~* 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.~* History of anaphylaxis post-vaccination.~* Hypersensitivity to latex.~* History of any reaction or hypersensitivity likely to be exacerbated by chloroquine.~* History of psoriasis and porphyria, which may be exacerbated after chloroquine treatment.~* Current use of medications known to cause drug reactions to chloroquine.~* History of severe reactions to mosquito bites.~* Major congenital defects.~* Serious chronic illness.~* History of any neurological disorders or seizures.~* 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.~  - Subjects with a minor illness without fever may be enrolled at the discretion of the investigator.~* Acute or chronic, clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by physical examination or laboratory screening tests.~* Any abnormal baseline laboratory screening tests: alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine, hemoglobin, platelet count, total white blood cells (WBC), out of normal range as defined in the protocol.~* Evidence of increased cardiovascular disease risk, moderate or high, according to the National health and nutrition examination survey I criteria.~* Hepatomegaly, right upper quadrant abdominal pain or tenderness.~* Personal history of autoimmune disease.~* 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.~* Pregnant or lactating female.~* History of chronic alcohol consumption and/or drug abuse.~* Female planning to become pregnant or planning to discontinue contraceptive precautions.~* History of blood donation within 56 days preceding enrolment.~* Any other significant finding that in the opinion of the investigator would increase the risk of having an adverse outcome from participating in this study.
