"All the 'easy' vaccines have been discovered," says Dr. Deborah Lewinsohn. But a TB vaccine is NOT one of them. Tuberculosis, though one of the oldest diseases known to humans, has always been one of the hardest to detect and treat. Deborah and her husband, Dr. David Lewinsohn, have devoted themselves to TB research at OHSU and the Oregon Veterans' Hospital.
Key to the Lewinsohns' work is that fact that most people infected with TB bacteria never develop the active disease. Not much is known about how their immune systems keep the disease at bay, but the Lewinsohns aim to find out. Learning that, perhaps, might show the way to the "holy grail" -- an effective vaccine to protect the world.
