It's already not 1; the s protein is actually a toxin that 'breaks off' and wreaks havok in the organs, specifcally the spleen, liver, testicles and ovaries, but also in the heart, lungs and brain. Essentially all the major systems.

Listen. If stuff are like what you say there will be literal mass deaths in USA and Israel as of now. 30% of the population in America is vaxxed, which in your theory should had been blatantly overflowed all the hospitals and caused mass hysteria inside America to the point that conservative states start locking down. Either that or government clicks a button and nukes all the vaccinated out of orbit. This is not the case.

If it's Sterlization I can still agree but there is a point where it starts resembling Solar Storm blasting us back to the stone age theories (which also require the sun to almost blow up).
