(Reuters) - When 22 bird flu experts meet at the World Health Organization this week, they will be tasked with deciding just how far scientists should go in creating lethal mutant viruses in the name of research.

The hurriedly assembled meeting is designed to try to settle an unprecedented row over a call to ban publication of two scientific studies which detail how to mutate H5N1 bird flu viruses into a form that could cause a deadly human pandemic.
But experts say whatever the outcome, no amount of censorship, global regulation or shutting down of research projects could stop rogue scientists getting the tools to create and release a pandemic H5N1 virus if they were intent on evil.
"It doesn't matter how much you restrict scientists from doing good, bad people can still do bad things," said Wendy Barclay, an expert in flu virology at Imperial College London.

The WHO called the meeting, for February 16 and 17 in Geneva, to work out how to break a deadlock between scientists who have studied the mutations needed to make H5N1 transmit between mammals and U.S. biosecurity chiefs who want their work censored or "redacted" before it goes into scientific journals.

Since the two research teams, one in the Netherlands and one in the United States, have found that just a small number of mutations would allow H5N1 to spread like ordinary flu between mammals - and remain just as deadly as it is now - the meeting is likely to be tense and highly secretive. WHO officials repeatedly stress it will be a "closed door" event.
DEEP CONCERN
The United Nations health body has said it is "deeply concerned about the potential negative consequences" of work by the two leading flu research teams who in December said they had found ways to make H5N1 into a easily transmissible form capable of causing lethal human pandemics.
Flu researchers from around the world - more than 30 teams in all - declared a 60-day moratorium starting on January 20 on "any research involving highly pathogenic avian influenza H5N1 viruses" that produce easily contagious forms of the virus.
The WHO has invited 22 people to this week's meeting, including the researchers who carried out the work, editors of the two journals, Science and Nature, who were asked to hold publication, and representatives from the U.S. National Science Advisory Board for Biosecurity (NSABB) which asked for the papers to be censored.
Keiji Fukuda, the WHO's assistant director-general for health security and environment, who will chair the meeting, says he would like to secure agreement on whether the studies should be published, in full or part, and who should have access to them.
The scientific know-how is seen as vital for scientists to be able to develop vaccines, diagnostic tests and anti-viral drugs that could be deployed in the event of an H5N1 pandemic.
"It is important that research on these viruses should continue," Fukuda told Reuters. "They do pose a risk. There's a lot of things we don't know about them. The question is not really should we continue to do research ... but under what conditions can we do it so we don't unnecessarily create fears and risks."
Michael Osterholm, policy director at the Minnesota Center of Excellence for Influenza Research and Surveillance and an NSABB member, has limited hope for what one meeting can achieve.
