Senior scientists have criticised the “appalling irresponsibility” of researchers in China who have deliberately created new strains of influenza virus in a veterinary laboratory.

They warned there is a danger that the new viral strains created by mixing bird-flu virus with human influenza could escape from the laboratory to cause a global pandemic killing millions of people.

Lord May of Oxford, a former government chief scientist and past president of the Royal Society, denounced the study published today in the journal Science as doing nothing to further the understanding and prevention of flu pandemics.

“They claim they are doing this to help develop vaccines and such like. In fact the real reason is that they are driven by blind ambition with no common sense whatsoever,” Lord May told The Independent.

“The record of containment in labs like this is not reassuring. They are taking it upon themselves to create human-to-human transmission of very dangerous viruses. It’s appallingly irresponsible,” he said.

The controversial study into viral mixing was carried out by a team led by Professor Hualan Chen, director of China’s National Avian Influenza Reference Laboratory at Harbin Veterinary Research Institute.

Professor Chen and her colleagues deliberately mixed the H5N1 bird-flu virus, which is highly lethal but not easily transmitted between people, with a 2009 strain of H1N1 flu virus, which is very infectious to humans.

When flu viruses come together by infecting the same cell they can swap genetic material and produce “hybrids” through the re-assortment of genes. The researchers were trying to emulate what happens in nature when animals such as pigs are co-infected with two different strains of virus, Professor Chen said.

Influenza experts have agreed to a two-month voluntary ban on research into a highly dangerous strain of bird-flu virus because of fears that it may escape from their laboratories to cause a global human epidemic.

In a joint letter to the journals Science and Nature, 39 researchers from around the world emphasise that their laboratories are safe and secure but they nevertheless acknowledge that there is grave public concern about the accidental or deliberate release of an “airborne” strain of H5N1 avian influenza which could be transmitted easily between people.

“We realise that organisations and governments around the world need time to find the best solutions for opportunities and challenges that stem from the work. To provide time for these discussions, we have agreed on a voluntary pause of 60 days on any research involving highly pathogenic influenza H5N1 viruses leading to the generation of viruses that are more transmissible in mammals,” the letter states.

Last month, the US Government announced that it had asked Science and Nature to withhold key details of two studies carried out in the US and the Netherlands where scientists mutated the H5N1 bird-flu strain into a form that could be transmitted easily between laboratory ferrets – the standard animal model for human influenza.

A deadly strain of bird flu with the potential to infect and kill millions of people has been created in a laboratory by European scientists – who now want to publish full details of how they did it.

The discovery has prompted fears within the US Government that the knowledge will fall into the hands of terrorists wanting to use it as a bio-weapon of mass destruction.

Some scientists are questioning whether the research should ever have been undertaken in a university laboratory, instead of at a military facility.

The US Government is now taking advice on whether the information is too dangerous to be published.

“The fear is that if you create something this deadly and it goes into a global pandemic, the mortality and cost to the world could be massive,” a senior scientific adviser to the US Government told The Independent, speaking on condition of anonymity.

“The worst-case scenario here is worse than anything you can imagine.”

For the first time the researchers have been able to mutate the H5N1 strain of avian influenza so that it can be transmitted easily through the air in coughs and sneezes. Until now, it was thought that H5N1 bird flu could only be transmitted between humans via very close physical contact.

Dutch scientists carried out the controversial research to discover how easy it was to genetically mutate H5N1 into a highly infectious “airborne” strain of human flu. They believe that the knowledge gained will be vital for the development of new vaccines and drugs.

But critics say the scientists have endangered the world by creating a highly dangerous form of flu which could escape from the laboratory – as well as opening a Pandora’s box for fanatical terrorists wishing to make a bio-weapon.

The H5N1 strain of avian influenza has killed hundreds of millions of birds since it first appeared in 1996, but has so far infected only about 600 people who came into direct contact with infected poultry.

What makes H5N1 so dangerous, though, is that it has killed about 60 per cent of those it has infected, making it one of the most lethal known forms of influenza in modern history – a deadliness moderated only by its inability (so far) to spread easily through airborne water droplets.

Leading scientists have condemned a decision by flu researchers to continue their controversial research into the deadly H5N1 bird-flu virus, which has already led to the creation of a mutated form of avian flu that can spread easily between mammals – including humans.

Forty of the world’s most prominent flu researchers have decided to lift their voluntary moratorium on studies into the airborne transmission of the H5N1 strain of bird-flu, which they imposed upon themselves last January following public outrage over the work.

They said that the benefits of the research in preventing and dealing with a future flu pandemic outweigh the risks of an accidental leak of the mutant virus from a laboratory or the deliberate attempt to create deadly strains of flu by terrorists or rogue governments.

However, other leading scientists vehemently denounced the decision on the grounds that it would be more dangerous to proceed with the research than to continue with the moratorium, claiming that there has been little discussion of the decision outside the flu-research community.

Professor Lord May, a former government chief scientist and past president of the Royal Society, said the moratorium should be continued because there are two possible downsides to research that deliberately aims at making the H5N1 bird-flu virus more infectious to humans.

“As this research becomes more widely known and disseminated, there is the opportunity for evil people to pervert it. My other concern is the statistics of containment are not what they ought to be,” Lord May told The Independent.

“The dangers of going ahead with the research outweigh the benefits of what may emerge. As I look at it, on the balance of probabilities, going ahead and lifting the moratorium is more dangerous than not going ahead,” he said.
