U.S. Continues Biological Warfare Research

merryprankster writes "Researchers at Saint Louis University have engineered a strain of mouse-pox virus which kills 100% of animals it infects - even when the mice have been treated with vaccination and anti-virals. The deadliness of the virus is related to the addition of a protein IL-4 which shuts down cell-mediated immune response. The engineered virus is not contagious and does not affect humans but the research has drawn some condemnation as being dangerous and unnecessary."
