Controversial lab studies that modify bird flu viruses in ways that could make them more risky to humans will soon resume after being on hold for more than 4 years. ScienceInsider has learned that last year, a U.S. government review panel quietly approved experiments proposed by two labs that were previously considered so dangerous that federal officials had imposed an unusual top-down moratorium on such research.
One of the projects has already received funding from the National Institutes of Health’s (NIH’s) National Institute of Allergy and Infectious Diseases (NIAID) in Bethesda, Maryland, and will start in a few weeks; the other is awaiting funding.
The outcome may not satisfy scientists who believe certain studies that aim to make pathogens more potent or more likely to spread in mammals are so risky they should be limited or even banned. Some are upset because the government’s review will not be made public. “After a deliberative process that cost $1 million for [a consultant’s] external study and consumed countless weeks and months of time for many scientists, we are now being asked to trust a completely opaque process where the outcome is to permit the continuation of dangerous experiments,“ says Harvard University epidemiologist Marc Lipsitch.
