This is a pair of binoculars in China. The purpose of the research is to give children natural immunity against certain diseases.
As most epistemologists point out, science is neither bad nor good, but depends on how it is used. For this reason, ethical debates within the scientific community often have a stellar space. However, it is very difficult for agreements to be absolute and there are always more permissive positions or even opposing interests.
In general, the edition of genes in human embryos is a practice that, at least for the moment, has been discarded. However, China does not seem to share international opinion. The first cases of modification of embryos took place in 2015. But it was only a laboratory experiment.
The next step was taken.
The University of Science and Technology of the South based in the city of Shenzhen recruited couples to perform gene modification as part of in vitro fertilization processes. The aim of these operations is to eliminate the CCR5 gene in the hope of making this child resistant to HIV, cholera and smallpox (the latter is considered eradicated in 1980).
The technique used is known as CRISPR. and it is relatively inexpensive. Embryos are modified before being transferred to the uterus.
Until recently, there was no birth confirmation. Only data from tests performed on fetuses up to 6 months of development were available.
However, He Jiankui the scientist responsible for all these efforts, pointed out that one of the women participating in the program She gave birth to two twins this month. He even posted a video on the subject.
Problems of Genetic Modification
One of the problems of genetic modification is that it can be used to prevent diseases, but also to create children at the convenience of their parents, or give them physical or mental improvement. There are also other risks badociated with the fact that many genes are not badociated with any characteristics.
