Tulane researchers working on new tuberculosis vaccine

Researchers at the Tulane National Primate Research Center (TNPRC) are leading efforts to find a new vaccine for tuberculosis, one of the world’s deadliest diseases. Tuberculosis, a contagious infection of the lungs, affected more than nine million people in 2013, killing more than one million. The team used Mycobacterium tuberculosis (Mtb) — a strain modified to lose a stress response gene called SigmaH. The study results revealed monkeys that received aerosols of the modified strain resisted infection with Mtb better than the similarly delivered BCG, and showed glimpses of protective immune response in their lungs.
