An experimental GlaxoSmithKline vaccine could prevent tuberculosis developing in half of those who receive it, making the vaccine potentially the first new shot against the global killer in a century.
EpicGenetics and Massachusetts General Hospital are launching a Phase II clinical trial to test a tuberculosis vaccine, CBG, as a potential treatment for fibromyalgia.
