LONDON, (BBC) - Scientists who created a potentially more deadly bird flu strain have temporarily stopped their research amid fears it could be used by terrorists.
In a letter published in Science and Nature, the teams call for an "international forum" to debate the risks and value of the studies.
US authorities last month asked the authors of the research to redact key details in forthcoming publications.
A government advisory panel suggested the data could be used by terrorists. Biosecurity experts fear a mutant form of the virus could spark a pandemic deadlier than the 1918-19 Spanish flu outbreak that killed up to 40 million people.
The National Science Advisory Board for Biosecurity (NSABB) recommended key details be omitted from publication of the research, which sparked international furore. "I would have preferred if this hadn't caused so much controversy, but it has happened and we can't change that," Ron Fouchier, a researcher from Erasmus Medical Center in Rotterdam, told Science Insider.
"So I think it's the right step to make." While bird flu is deadly, its reach has been limited because it is not transmissible between humans.
However, the H5N1 flu virus was altered to be passed easily between ferrets, during the joint research by Erasmus University in the Netherlands and the University of Wisconsin-Madison in the US.
Two scientific journals want to publish the research -- albeit in redacted form -- and are trying to work out with the US government how to make the data accessible to "responsible scientists".
The World Health Organization said in a December statement that limiting access to the research would harm an agreement between its members.
The NSABB is made up of scientists and public health experts, 23 from outside the government, and 18 from within. It cannot stop publication but makes recommendations to researchers. The scientists' letter published on Friday argues that knowledge of more infectious strains before they mutate in nature is valuable for public health.
"More research is needed to determine how influenza viruses in nature become human pandemic threats," the statement says, "so that they can be contained before they acquire the ability to transmit from human to human, or so that appropriate countermeasures can be deployed if adaptation to humans occurs." |
