This is pretty silly. If you're paying $860k for something (note this is USD being spent within China), you can afford to do basic research on what you're getting involved with, which they apparently did:

> The parents had heard about serious side effects, including deaths, caused by other gene therapies, and knew the greatest risk would be Mei’s immune response to the massive dose of virus.

The risk was explicitly stated in the consent form:

> The platelets in her blood also dropped to dangerous levels. It was the exact sequence of symptoms that the consent form had warned the family about.

Qiu should have been more cautious in some of their communication with the obviously emotional parents, but this is pretty far from a scam and these aren't nobody doctors within China. He had a postdoc from UC San Diego, was a well known neuroscientist in China, published in Nature, etc.

There is a meaningful difference between knowing that gene therapy can cause serious complications in general and being told that every treated monkey developed moderate to severe liver damage, with one also showing kidney damage consistent with the mechanism that ultimately killed the child. Informed consent was pretty hard to get here
