Jiankui, a Chinese scholar, defended the work that led to the birth of today. first genetically modified babiesA case with deep medical and ethical consequences that constitutes a strong rejection among the world scientific community. He explained that there was a second pregnancy going on and that he would m pause ya in his clinical trials.
Jiankui, a 34-year-old associate professor in the city of South Shenzhen, unveiled another possible pregnancy in his initial public statements about his controversial study at an international conference in Hong Kong.
I said that The two twins born earlier this month have changed DNA to immunize against HIV. The scientific community condemns the experiment and investigates the situation of universities and government groups.
The second possible pregnancy is at a very early stage and more time is needed to confirm whether it will continue.

After talking, leading scientists said it now there's more reason to worry than ever and more questions than answers. Director of the conference called the experiment "irresponsible"He said the scientific community could not self-regulate and that it was evidence that it avoided initial efforts to alter the DNA.
Replacing DNA before or during pregnancy is a highly controversial issue because changes can be hereditary and harm other genes. This app is forbidden in some countriesExcept for the case of laboratory research, including the United States.
In order to test for genetic regulation, I advocated HIV as a fatal congenital disease and insisted that girls could benefit. Çünkü They need this protection because the vaccine doesn't exist, Araştırma the researcher said. However, scientists did not approve their approach.
In a health conference at a crowded amphitheater in Hong Kong on Wednesday, He Jiankui reiterated that allowing twins to be changed to make DNA resistant to the AIDS virus.
He also explained that eight pairs of a seropositive father and a seronegative mother were voluntary for the trial, but one of them retreated.
"I apologize for having missed an unexpected result," Jiankui said on Sunday on YouTube, referring to videos announcing the birth of the twins Lulu and Nana. Said.
"There is a break in clinical trials due to the current situation.Added a scientist who operates a laboratory in Shenzhen.
"This is a really unacceptable stepIS Jennifer Doudna, a scientist from the University of California-Berkeley and one of the inventors of the CRISPR gene editing tool,-she said. "I'm grateful you're seen today, but I don't think we hear the answers." Understand the motivation for this. "
At present, the O / s claim has no independent approval. has not published any scientific journal researches yet Can be tested by experts. At the conference, he refused to answer a number of questions, including who paid the study, including the participants' understanding of the possible risks and benefits, and why he held the business secret until it was completed.
Regulators are in a hurry to condemn the experiment unethical and unscientific.
The China National Health Commission asked the local authorities in Guangdong province to investigate the actions of O & # 39; s and the center of the University of Science and Technology.
