Nor did the procedure fulfil any unmet medical need. For the child whose genome was edited to confer resistance, the claimed benefit is protection from a virus that she may never encounter (although her father is HIV-positive, his sperm were washed to prevent infection during fertilisation) and for which there is a good, and improving, standard of care. If the reports are correct, the second child has been exposed to the potential risks of an edited genome but can still be infected by HIV.

The idea that one scientist could make the leap towards editing reproductive cells has been condemned, but it has not been ruled out. Even if Mr He turns out to be a fraud, others have the means, the motive and the opportunity to do similar work. CRISPR is not a complex technology. That leads to two responses.
一位科学家可在编辑生殖细胞方面取得很大进步的这种观点遭到谴责,但并没有被完全否定34F#%#0XujdA2K3=。即使贺建奎欺诈,其他人还是有方式、有动机、有机会做出类似的事情WMI&n,52t%|M83u|Xz6。CRISPR技术并不复杂,nsqr^5_wdI&IC#ov%。可有两种应对办法c1Gy=DS]#)qBq5d
The first is practical: better oversight of places such as fertility clinics, where back-room genome-tinkerers may lurk. That applies not just in China, where Mr He has attracted vocal condemnation, but also in America, where IVF clinics could use greater regulatory scrutiny.
第一种针对实际:对生育诊所等可能潜伏着幕后基因修补者的地方加强监管lEkR|BD@k%DnfUE(-v。这不仅适用于贺建奎招致声讨的中国,也适用于试管婴儿诊所还需加大监管审查力度的美国s0V&QC,]7J
The second is proper debate about when gene-editing is warranted. Editing the unhealthy cells of those suffering from genetic diseases such as Duchenne’s muscular dystrophy and cystic fibrosis will alleviate their suffering. It is less clear when it is necessary to edit embryos, but Mr He’s experiment obviously fails the test. Fertility treatments already screen embryos for unwanted genes.
第二种是适当争论,主要关于基因编辑在何时恰当需要6hK(enf[-6ePN。编辑那些患有杜氏肌营养不良和囊性纤维化等遗传疾病的人的不健康细胞将减轻患者痛苦[s[_s~)G6fG;e。何时需要编辑胚胎还不清楚,但贺建奎的实验显然未经测试uwfZr|(!(BBwFU|hrN。生育治疗已经在筛选多余的基因c^pUH48E3Uav=Kr
It may even be that editing will one day be used on embryos to enhance genomes (to make people cleverer, say), rather than to cure disease. But that requires regulators, policymakers, scientists and civil society to think through deep ethical questions. Work is already under way to develop principles for editing reproductive cells. Earlier this year the Nuffield Council on Bioethics, a think-tank in Britain, outlined two: that the changes brought about by gene-editing should not increase “disadvantage, discrimination or division in society” and that such changes should not harm the welfare of the future person. Such debate was always going to be needed. Now it is urgent.
