According to The Washington Post, National Institutes of Health Director Francis Collins told reporters that the government has developed a new, stringent policy outlining the justifications necessary for such risky investigations to receive money. “This kind of research can only be conducted in a very few places that have the highest level of containment,” Collins said.

The ban emerged in 2014 after a series of concerning events. In 2012, researchers had developed an influenza virus that ferrets could catch through the air. Then in 2014, biosafety mishaps shook up federal agencies—one involved staff being exposed to anthrax, another with forgotten vials of smallpox that were discovered in a storage facility.
