TB Protein Discovery Could Lead to Better Vax

UK scientists identified a protein secreted by tuberculosis bacteria that could become a vaccine target. As Imperial College of London professor Ajit Lalvani said, the EspC protein stimulates a strong immune response in humans, and it's also quite specific to TB bacteria, making it "an extremely promising candidate" for a new vaccine.

With tuberculosis bacteria growing more and more resistant to drug therapy--and the only current vaccine against it, the BCG shot, less-than-perfectly effective--scientists have been scouting for new way
