The synthetic spike proteins are NOT just replicas of part of the COVID virus. These pharmaceutical korporations could have used actual inert viruses like they do with true vaccines alongside the synthetic tests if that were the case.
These banned gain-of-function experiments create spike proteins that are designed to carry additional compounds into the body and trigger different results than humans would normally do.
One idealistic goal was to have individuals create a response that they could "shed" and infect others with. The intent was to spread immunity through infection but it's uncontrollable.
I didn’t mean it that way, I meant it in the sense that they are the harmful part of the Covid virus, so in part can cause what are perceived to be Covid symptoms.
Of course there’s a lot more to the mRNA “operating system” as injected, including nanoparticle delivery to all body organs, than just that.
