Oct. 18, 2005 -- The antiviral drug being hurriedly stockpiled by governments worldwide may not be reliable protection against bird flu, a U. S.preparedness official warned Tuesday. Experts have long said that Tamiflu is not a cure for bird flu, but the drug could help slow the severity or spread of the disease in the event of a human pandemic. Governments have rushed to order stocks, prompting a worldwide run on the drug and criticism of its manufacturer for apparent refusal to share its patent with generic drugmakers. But even that assessment may be overly optimistic, Michael Osterholm, MD, told reporters Tuesday. Osterholm is associate director of the National Center for Food Protection and Defense within the Department of Homeland Security. usa online casino s no deposit blackjack ballroom casino spyware gambling in legal info on online gambling facts on online gambling
