Synthetic Biology's Question

Will science be able to go so far as to change 
genetically transmitted diseases for the benefit 
of man?

Yes of course. This is one of the main goals of 
the "synthetic biology".
People who said that one of the vaccines is 
gene therapy, it will be a major experiment that will show us if 
we can go in the direction of truth soon, to 
replace human genes.

Who ... what will be the main experiment?

Well, one of the vaccines so widely given that 
it eventually delivers the gene inside our cells to synthesize the proteins of the virus, it ultimately introduces external genetic 
material in a very easy way, into a large 
number of our cells, which is one brave experiment. ... And how it seems to be so successful, that it paves the way for gene therapy very 
seriously. Which has so far been hampered by moral 
restraints, by regulatory restraints.

Is this … is it the RNA vaccine?

Yes, and the RNA and DNA vaccines, both, 
but the RNA vaccine is especially plentiful.
