Current scientific techniques are not yet safe or effective enough to be used to create gene-edited babies, an international committee says.
The technology could one day prevent parents from passing on heritable diseases to children, but the committee says much more research is needed.
The world's first gene-edited babies were born in China in November 2018. The scientist responsible was jailed, amid a fierce global backlash. The committee was set up in response.
