| The safety profile will be assessed on the basis of the following criteria �� Immediate reactogenicity (any event occurring within the first three (3) hours after each vaccination, with emphasis on allergic reactions) �� Local and systemic reactogenicity (any event occurring from three (3) hours post vaccination on Day 0 till Day 14 after each dose) �� Any unsolicited adverse events 28 days after each vaccination �� Any Serious Adverse Event (SAE) occurring from the first dose of vaccine till the last follow-up visit. �� Biological safety, 28 days after each vaccination, in reference with the baseline before the first dose, by measuring the following parameters: ? Haematology: RBC Count, Haemoglobin*, Haematocrit/Packed Cell Volume (PCV), MCV (Mean Corpuscular Volume), MCH (Mean Corpuscular Haemoglobin), MCHC (Mean Corpuscular Haemoglobin Concentration) on Days -14, 28, 56, 180, 208, 365 ? Platelet Count and Total Leukocyte Count (TLC) along with Differential Leukocyte Count (DLC) on Days -14, 28, 56, 180, 208, 365. *If the haemoglobin drops below 13 gm/dL, then a direct Coomb?s test and a peripheral blood smear/film will be prepared and examined for evidence of possible haemolysis ? Serum Chemistry: Potassium, Sodium, AST, ALT, Direct, Indirect and Total Bilirubin, Alkaline Phosphatase, Gamma Glutamyl Transpeptidase (γGT), Creatinine, and Random blood glucose on Days -14, 28, 56, 180, 208, 365 The Investigator will be responsible for causality assessment i.e. assessment of the relationship of the AE to either of the assigned the study vaccines, using the following definitions: related or not related.Timepoint: NA | — |

| ? The humoral response to the candidate vaccine antigen will be assessed (quantitative assessment) by measuring the level of IgG antibodies developed against PfMSP-119 and PfF2 by ELISA on Days 0, 28, 56, 180, 208 and 365 ? The humoral response to the candidate vaccine antigen will be assessed (qualitative assessment) to verify the ability of the IgG antibodies developed against PfMSP-119 and PfF2 to recognise the native proteins, namely, PfMSP1 and EBA175 in late stage P. falciparum schizonts and merozoites by IFA on Days 0, 28, 56, 180, 208 and 365.
