Rash rush to genetically modify humans

China Daily | Updated: 2018-11-28 07:05

Unwise as CCR5 gene also vital to immune system

It is irrational and unwise to edit the CCR5 gene of a healthy human embryo, because the gene is of importance to the normal functioning of human immune cells. Before we can be 100 percent sure about the reliability of CCR5 editing, the technology should not be used on humans.

Besides, even if a mother carries HIV, there is safe and reliable technology that has a 98 percent chance of preventing the newborn from being infected.

Embryos unable to give their consent

As a doctor with knowledge about medical ethics, I feel worried about the experiment. According to the law, medical tests can only be done with the consent of the subjects, or people who receive the tests, while the plan must be safe and the subjects' privacy be protected.

In He's case, the two babies as subjects were put into a test before they were born, so it was impossible to obtain their consent in advance. It was improper for the parents to give their consent instead of them.

Besides, the researchers claimed their "research" can make the babies immune to HIV. How will they prove that? And will they subject the two newborns to tests in the future? That is illegal and will only further violate the two children's rights.

Violation of bottom line, not a breakthrough

A main reason for the incident having aroused so much attention is some people have misunderstood He's deeds as a "breakthrough in technology". Actually, the technology has long existed, and all he did was to apply it in a field where no medical professional had dared go before. So his deed is far from a scientific breakthrough. It is more a violation of the ethical bottom line.

Gene editing has already reaped many benefits

It is irresponsible to edit human genes without safety and ethical approvals, but do not defame the technology of geneediting, which is neutral and has already produced many benefits. It is better to limit the technology in transparent ways, and ensure that its use is under control.

Scientist at center of storm previously urged caution

We should take a very careful view toward gene-editing technology, because any failure might lead to the doom of the whole research field.
