I'm still not clear on this. I understand all of these "vaccines" (most of them, at least the ones in the U.S.) have been created based on a sequencing of the genome of the virus, not an actual isolated copy of the virus itself. The traditional sort of vaccine would have been based on the latter. Has the SARS-CoV-2 virus ever been successfully isolated?
I don’t know my guess is “no” but that this technology/approach comes from years of research attempting to do that.
Here is one of dozens of research groups that has sequenced the SARS Covid 2 sequence set down to the individual code base. It’s a myth that no one has sequenced it. This bug is easily the most decoded gene set on the whole planet at this point. Hundreds of labs around the world have isolated live virus and decoded it.
