The BBC reports that a new drug named 'Draco' has the potential to kill cold viruses, swine flu, polio, dengue, and Ebola. Other drugs like interferon which work against viruses tend to produce an immune response that causes intense side effects; Draco appeared not to spark such a response.

Tests done on mice yielded positive results, but they have yet to be tested on actual humans.
Says immunologist Hugh Pennington, "No-one can say when the next pandemic will occur, it may be next year or it may be in 100 years' time. [...] If we had a wonder drug like Draco might be, we could sleep much easier at night." However, some scientists are still skeptical, like Dr. Leo James. He says:  "It is potentially very exciting but because the results are so unusual and because it was published in an unusual journal it needs to be proven by others."
