The Vaccine That Came In From the Cold

The Vaccine That Came In From the Cold - ScienceNOW:

"Scientists say they may have discovered a way to develop cool new vaccines—and they mean that literally. By replacing essential genes in a mammalian pathogen with their counterparts from Arctic bacteria, they have created strains that provoke a protective immune response in mice—but that don't spread to the warm parts of the body where they could do serious harm. The team hopes that the method will lead to a new generation of vaccines for major bacterial diseases such as tuberculosis."
