Studies reveal how plague disables immune system, and how to exploit the process to make a vaccine

...er, many people have worried that terrorists could exploit Y. pestis as a weapon, spreading it widely and rapidly as an aerosol rather than through fleabites and rodents. Contracted this way -- infecting the lungs rather than the bloodstream -- the disease is known as pneumonic plague. This form of the infec...
