'Immune-Boosting' Drug Actually Worsens TB

An experimental drug called poly-ICLC, intended to boost production of the immune system protein interferon, has actually been shown to worsen tuberculosis (TB) in mice.

The drug ends up drawing immune cells in which tuberculosis bacteria thrive directly into the lungs.

Poly-ICLC stimulates your body to produce a potent immune system protein called type I interferon, named for its ability to interfere with viral infections.
