GENEVA (Reuters) - Using antiviral Tamiflu could halve the potential death toll from an influenza pandemic if it was used both to treat and prevent the disease, its maker Roche said on Friday.Research presented by Beate Sander of the University of Toronto, Canada, showed a stockpile of Tamiflu sufficient to cover 65 percent of a country’s population could cut deaths by approximately half, Roche said.
