New study on smallpox in monkeys reveals tactics of a killer
..., on a molecular level, the smallpox virus attacks its
victims. The findings shed light on how the virus caused mass death and suffering, and will help point the way to new diagnostics, vaccines and drugs that would be needed in the event of a smallpox bioterror incident. The study, led by David Relman, ...
