Ongeveer zoals Twelve Monkeys begon, zeg maar:
Scientists have created a life-threatening virus that closely resembles the 1918 Spanish flu strain that killed an estimated 50m people in an experiment labelled as "crazy" by opponents.
US researchers said the experiments were crucial for understanding the public health risk posed by viruses currently circulating in wild birds, but critics condemned the studies as dangerous and called on funders to stop the work. [...]
"The work they are doing is absolutely crazy. The whole thing is exceedingly dangerous," said Lord May, the former president of the Royal Society and one time chief science adviser to the UK government. "Yes, there is a danger, but it's not arising form the viruses out there in the animals, it's arising from the labs of grossly ambitious people." [...]
The work is the latest in a series of controversial studies that have split the scientific community. On the one side are researchers who create dangerous viruses in secure labs in the hope of learning how existing strains could mutate to make them a potential threat to humans. On the other are scientists who argue the work does little or nothing to help protect people, but instead puts the global population in more danger.
Marc Lipsitch, professor of epidemiology at Harvard School of Public Health, said: "I am worried that this signals a growing trend to make transmissible novel viruses willy-nilly, without strong public health rationale. This is a risky activity, even in the safest labs. Scientists should not take such risks without strong evidence that the work could save lives, which this paper does not provide," he added.
