There is no guarantee that Tamiflu or any of the other anti-viral remedies will be effective against a mutated H5N1 virurs. As a matter of fact, there is evidence extracted from the young 14YO Vietnamese girl who was treated with Tamiflu that some of the little viral critters had mutated to become resistant to Tamiflu. At this early stage, when so little is really known, I kind of like the fact that the Federal Government isn't rushing to dump billions of money that we don't have into a possible waste of time and money.
