1 vaccine to prevent Tuberculosis, leprosy

Washington: Scientists from the University of California  have found that a variant of an existing vaccine offers stronger protection against both tuberculosis and leprosy. The available vaccine, Bacille Calmette-Guerin, or BCG, provides partial protection against TB and leprosy. Researchers found that rBCG30, a recombinant variant of BCG overexpresses an abundant 30 kDa protein of tuberculosis bacterium Antigen 85B, is superior to BCG.
