Despite plaguing humans for thousands of years, tuberculosis remains a widespread and lethal public health
problem throughout the world today. The recent rise of multi-drug-resistant tuberculosis (MDR-TB) perpetuates the public health threat while presenting a potential bioterrorism agent. The BCG vaccine is the only available prevention against TB, yet it elicits inconsistent protection when given to infants, fails to provide consistent protection in adults against pulmonary disease, and is unsafe for use in immunocompromised patients. A new crop of TB vaccine candidates has entered into clinical trials, with a second generation following shortly. These new TB vaccines are hoped to provide a safe, efficacious replacement, or addition to, the nearly century-old BCG and provide protection against TB disease beyond childhood. This review details the status of the most promising TB vaccine candidates in development, as one of these candidates may play a key role in defending against an ominous health threat.
