If everybody were vaccinated, then any potential side effects could be put off as "chronic or genetic" diseases.
Could help build blind faith in future vaccines with potentially deadlier outcomes, or pave the ground for selective annihilation.
The reason I don't think the current vaccine will depopulate the earth is because the cabal certainly does not want the sheep to go extinct, with all of us remaining in tact. The above would then provide one potential way to close the gaps in what seems like an over the top push for getting vaccinated despite well knowing that so many of us will never take it.
They're pushing it out because by itself it is not lethal. They need a reagent to react with it in order to kill you -- that's phase 2 of the plan.
We need to stop them before they go to task or 50% of the world pop could die.
They need to influence minds to do the work for them because the task is too large for them to carry it out by themselves.
