Chinese scientists today Jiankui He apologized for the controversial genetic modification reveals two newborns to make them resistant to HIV-AIDS and recognized the biological risks of this practice in the human body.
He acknowledged the serious consequences of the trial for the individual and his descendants, indicating that they had made the couple aware of this situation before sending her for treatment.
According to him, only the father of the twins Lulu and Nana is infected with HIV, and using the Crispr-Cas9 method for gene mutation allowed them to be born with resistance to the virus that causes AIDS.
She indicated that there are still no signs of anomalies in the girls, and as part of the plan, her team will follow her until they reach 18 years of age and adulthood.
Finally, he announced the development of another possible pregnancy, also with gene modification in embryos.
I thus broke the silence after a three-day dispute and a wave of rejection that a report on his experiment originated inside and outside the country.
Earlier this week, he distributed a YouTube video in which he himself announced a recent birth in the excellent health of Lulu and Nana after using Crispr-Cas9.
This procedure is also known as “genetic scissors”, and it allows you to remove and replace unwanted parts of the genome in the same way that a bug is fixed on a computer.
According to He, babies were born by in vitro fertilization of a modified embryo before implantation into the mother’s womb.
The institutions of the state and the scientific community of China oppose the trial, describe it as illegal and violate ethical and moral norms.
Even a team from the National Health Commission is investigating this matter.
