proof novel spike protein is the poison, why inject 80% kill rate?

[turinreza]

scientist replace omicron strain spike protein with original spike protein
(the alpha spike protein) leading to easy spreading and lethal 80% kill rate

the latest booster is Bivalent which has the original alpha spike protein in addition to omicron spike protein.

If the original covid spike protein is so deadly to cause 80% why would
anyone want to inject anything with the original spike protein?

the mRNA vaxxines and boosters , if they allow cells to replicate the original spike protein all over the body (many cases that it spreads beyond the injection site) why would anyone want to take these vaxxines if they contain the spike protein that makes omicron 80% deadly?

Obviously they didn't kill enough people the first time, so this is cleanup.
