Watch this one, CRXL
According to Business Week Magazine, they are developing a West Nile vaccine. It's yet to be formally announced, but the PR may come out today. If it does, it will take off by the $$$$, I predict.
Here's a note about it on Yahoo:
"7:04AM Crucell N.V. highlighted as West Nile play in Business Week (CRXL) 4.10: Business Week reports that this small Dutch biotech outfit recently signed a yet-to-be-announced agreement with the National Institutes of Health to develop a vaccine against West Nile. A money manager who refused to be named has bought 500,000 shares and says a West Nile vaccine could produce huge revenues for Crucell."
