A Vietnamese doctor who has treated dozens of victims of avian flu claims the drug being stockpiled around the world to combat a pandemic is 'useless' against the virus. Dr Nguyen Tuong Van runs the intensive care unit at the Centre for Tropical Diseases in Hanoi and has treated 41 victims of H5N1. Van followed World Health Organisation (WHO) guidelines and gave her patients Tamiflu, but concluded it had no effect. 'We place no importance on using this drug on our patients,' she said. 'Tamiflu is really only meant for treating ordinary type A flu. It was not designed to combat H5N1 . . . (Tamiflu) is useless.' Roche, the company that makes Tamiflu, has sold stockpiles of the drug to 40 countries and insists there is clear evidence it will protect against a future flu virus. However, it stresses the drug must be given within 48 hours to be effective. The WHO admitted Tamiflu had not been widely successful in humans. 'However, we believe in many Asian countries it hasn't been used until late in the illness,' a spokesman said.

Each news summary is created according to strict standards. Here's how we do it.
Each summary is created using a consistent editorial procedure. The target length is approximately 16 lines of 11-point Arial text in a 650-pixel-wide column. Up to 25% of a summary may be set in bold to emphasize the most important ideas. Summaries are composed of verbatim excerpts presented in the same sequence as they appear in the original news source, with very minor editorial additions. Where material has been omitted between excerpts, the omission is indicated with ellipses (...). Any words added by an editor for clarity or context appear in [brackets]. Our original news editor was Fred Burks. Tod Fletcher edited most summaries from 2007 through 2014, and Mark Bailey has served as news editor since 2014.
