Observational Study

Tuberculosis

Background

MTB infection causing TB disease is one of the top 10 causes of death worldwide. The most effective contribution to controlling TB is vaccination. BCG is the only licensed vaccine; however, this vaccine does not provide substantial protection against pulmonary TB in adults infected with MTB. GlaxoSmithKline Biologicals, SA (GSK) has developed M72/AS01E, a TB vaccine candidate to protect against TB in adolescents and adults. The IGRA study will help refine the sample size and duration required for phase 3 studies.
