NIH has already started testing HIV drug lamivudine against Ebola

[magical thyme]

so far, in test tubes there has been no reaction. They are trying with different dosages and if they get a reaction, may go to trial.

"Fauci said National Institutes of Health researchers have tested lamivudine's reaction to Ebola in test tubes. There was no response; but Fauci said researchers will adjust some levels and try it again "to see if there's even slight activity against Ebola."

If there is, he said, NIH would consider going to the trial stage."
