Chinese scientist He Jiankui claims to have made the first gene-edited babies using CRISPR. In a clinical trial, create embryos through in vitro fertilisation from couples where the father was HIV-positive. The team then edited the embryos using CRISPR to deactivate the CCR5 gene, which the HIV virus uses to gain entry into human cells. News of the trial has been condemned by scientists as irresponsible.
