NCT00052195

Brief Summary

A significant number of HIV infected patients in Africa also have disseminated tuberculosis (infection throughout multiple organs). This type of tuberculosis is a significant cause of mortality in these patients. The purpose of this study is to evaluate the safety and effectiveness of a vaccine designed to prevent disseminated tuberculosis.
