In the fall, said He Jiankui, 34, that he is in an experiment had managed to changed a couple of tvillingflickors dna in order to make them resistant to aids. Now comes the information that yet another woman has become pregnant during the trial.
their findings at the conference in Hong kong, he stated that eight voluntary couples – hiv-positive fathers and hiv-negative mothers enrolled in the experiment, of which a couple later dropped out of. He also said that, besides the twins, there was even a ”potential pregnancy”, writes The Guardian.
Now confirm the chinese authorities the task. According to the authorities, who have reviewed He, a woman is still pregnant and she as well as tvillingflickorna from the first pregnancy will be under medical observation, ” says an investigator to the Xinhua news agency.
before or during conception is very controversial, and the experiment has been met with both criticism and concern. Scientists warn that a modification can have serious consequences, because it may cause harm to other genes and affect the entire genome for future generations. With the exception of research in the laboratory is the genetic modification is prohibited in a number of countries including Sweden and China.
If the Hes data is true, it is the first time such intervention has been made. But he has not published their findings in any scientific writing, therefore, other researchers have not been able to review the results of the research.
In China stopped the authorities immediately He started an investigation.
to the department of science and technology at the university of Shenzhen, but the experiment is according to the investigation carried out on false pretenses and illegal. According to the investigators were, He probably have used fraudulent documents in order to be able to carry out ivf on the pairs.
After the Hes experiments, researchers have called for an international agreement for guidelines on targeting.
