Some of this theory you've heard before, but I'm going to add some detail and definition.
The vaccines were never supposed to be harmful. The deep state only started spiking batches as a way to punish white hats and the public for not following their original 10 year plan. They're petty like that.
Trump and the white hats knew Moderna developed the vaccine before the virus was released from Wuhan, so he threatened to expose the entire pharma industry if they didn't release the vaccines in 2020 instead of 10 years later as planned. Trump short-circuited their plan to destroy the world.
So the plan of the white hats was to proceed with mass vaccinations as a pretense for ending Covid. That narrative started being accepted by the public and Trump was getting credit, so the deep state shifted to plan B by spiking batches and killing people.
At this point, the white hats must continue with their pro-vaccine plan because shifting Trump to an anti-vax position would allow the media to conjure up a new narrative that anti-vaxxer Trump and his "cultists" caused Covid to resurge. The "Return of Covid" would bring us back to plan A of a 10 year pandemic, and history would scapegoat Trump.
So why is the deep state pushing the vaccines so aggressively? Because they've already committed to plan B, and they must achieve the plan's goals of engorging big pharma with money while killing as many people as they can get away with. They can't switch back to plan A unless Trump goes anti-vax.
Are we helping the deep state by not getting "vaccinated"? No, because they've already committed to plan B which involves ending Covid relatively soon. If it doesn't end soon, the public would abandon vaccines altogether, which will cause the deep state to lose all control of the narrative. And that's really all the vaccines are: Another tool to control the Covid narrative. Also, in plan B, they cannot scapegoat Trump supporters because left wingers are joining us now. Trump remaining pro-vax is helping to onboard lefties to our position.
So does Trump know vaccines are killing people? Yes, but he has to stay the course because this is war. Doing otherwise would allow the deep state to take control of the objective.
In the bigger picture, yes, this was one of the purposes.
