In a report to the US Congress, the Department of Defense revealed that its program of creating artificial biological agents included modifying non-fatal viruses to make them lethal, and genetic engineering to alter the immunology of biological agents to make treatment and vaccinations impossible. The military report admitted that at the time it operated about 130 bio-weapons research facilities, dozens at US universities and others at many international sites outside the purview of the US Congress and the jurisdiction of the courts.
