A research team backed by a federal grant has created a genetically engineered mousepox virus designed to evade vaccines, underscoring biotechnology's deadly potential and stirring debate over ...

WASHINGTON — Scientists in St. Louis have created a genetically altered strain of mousepox virus that is so potent it kills mice vaccinated against the mouse disease, rekindling concerns that ...

The virus, a modified mousepox, does not affect humans, but it is closely related to smallpox, raising fears that the technology could be used in biowarfare. The discovery highlights a growing ...

The new insights into the immune response of mice to the mousepox virus could enable scientists to combine antivirals and cytokines such as such as gamma interferon to increase the efficacy of the ...
