I see that. this makes ADVR (US bulletin board) and VRA (Amex) into interesting stories with upside. Advanced Viral Research and Viragen respectively.
I am not sure what upside means financially, are you?
Other upsides may be protease inhibitor companies. Do you know of any who hae protease inhibition drugs in the pipeline? there were several biophars that had advanced projects a while back and shelved them. No doubt they are bringing them out of the woodwork now.
