Swine flu: Who's winning and losing in the H1N1 virus pandemic?

President Obama declared the H1N1 flu outbreak a national emergency last weekend. While U.S. officials insist the move is not a reaction to new developments but a preventive measure, it comes just as the vaccine shortage has been making headlines, with the Centers for Disease Control "frustrated" by the tight supply of vaccine -- and Friday's report that swine flu, still on the rise in schools, has forced 315 schools to temporarily shut down.

Of course, in times of crisis, some always benefit while others take a hit, and one drug company that's done rather well by the H1N1 pandemic is vaccine-maker Novavax (NVAX).
