I get it.
Perfect setup for Phase II: vaccine victims' immune systems are totally committed to defend against the old mostly non-lethal strain.

Victims' innate immune system suppressed by specific antibodies dedicated to the old non-lethal strain, and now cannot adapt because cells are only producing the old spike protein, and can't change back due to permanent DNA revision.

Let immune escape breed the super bug in the vaccinated who have partial, variant breeding immunity, and continue to shed any new mutated variants.

Wait till the new lethal vaccine resistant virus breeds, it won't take long since so many are vaccinated. In the meantime, give the vaccinated a passport and encourage them to travel widely, now without precautions.

Announce new vaccines when COVID surges due to rapid spread of the newly bred super strains.

Blame the new outbreak loudly on the unvaccinated so more vaccination compliance boosts ongoing immune escape.

During the height of the new panic, release the second, more lethal lab created weapon. Blame this on the unvaccinated too.

Rinse and repeat
