I think you are misunderstanding what Shifter is saying. If I'm reading this correctly, he wants a Super nCov-19 that is even more contagious, but doesn't have any of the bad symptoms, and still grants you immunity to the real COVID.
It's similar in concept to how they control malaria in some places. They release a ton of sterile male mosquitos that still really really want to mate with the females, they are just shooting blanks so they don't make babies.
Aaa i see.
A variant that is actually just as infectious but wihout the sympotms.
The porblem is how virus viruses.
Just like any scifi where the nanobots or replicas take over.
A virus tells the cell to make virus.
The cell makes virus until it bursts, unleashing more viruses.
The immune systme is playing catchup at this point.
Part of that is kiling cells in process of making viruses too.
So the body starts just killing cells.
The problem with this covid is the ability to get in.
Its these spikes are so good.
Think reverse sperm.
Ans infecting so much of the body so quickly exponentially.
So your body is killing massive parts of itself which is the problem.

From what i gather.
Im obviously just some guy on the internet who wafched a few youtubes.
