CRISPR just started trials this year in the US. It is going to take a very long time to prove safety is not an issue, as I have read it has had issue with cancer by mutation on things it shouldn’t.

Also other gene therapy of the past had disastrous results, so they move slower this time. Probably done it life or death situations first I would imagine, like cancer. I really hope the get the technology right, because it has big implications for all of us.

WASHINGTON - A patient in a gene therapy experiment died on Tuesday in what appears to have been a reaction to a novel treatment for arthritis, federal health officials said late Thursday.
The precise cause of death remains unexplained. But the event immediately revived memories of a similar tragedy in 1999, when teenager Jesse Gelsinger succumbed in a gene therapy test in which researchers at the University of Pennsylvania were eventually shown to have violated safety rules.
That disaster was a major setback for the field, which for more than 15 years has sought to treat diseases by giving people new genes. The only documented successes - in a handful of children - were undermined when the treatment was found to have caused cancer in some.
Food and Drug Administration officials said they were notified by Seattle-based Targeted Genetics last Friday that a patient had experienced a "serious adverse event," regulatory code for a life-threatening reaction. The agency immediately shut down the study pending more information. Four days later the patient died.
