Trial overview
Official title: Evaluation of the kinetics of mRNA expression after two doses of GSK Biologicals’ candidate tuberculosis (Tuberculosis) vaccine GSK 692342 in healthy adults
Trial description: The purpose of this study is to assess the safety and immunogenicity of two doses of the TB vaccine administered according to a 0, 1 month schedule. In, addition, blood samples collected at different time points after vaccination will be analysed to see when exactly genes are activated by the vaccine using an assay called mRNA expression profiling. The different methods for mRNA expression profiling using whole blood samples versus Peripheral Blood Mononuclear cell(s) (PBMCs), will also be compared.
