A study provides new clues to what went wrong with a landmark TB vaccine trial in South Africa. The vaccine -- tested in nearly 2,800 infants -- did not offer extra protection against developing tuberculosis, which last year killed 1.5 million people. South Africa has the second highest rate of TB cases and the highest rate of drug-resistant TB in Africa, according to the Centers for Disease Control and Prevention.
