What if the vaccines are safe and have something in them that will prevent illness from the next virus that is unleashed. The future will need slaves to do all of the things robots and A.I. cannot and the real threat to them is the radical free thinkers. We are the ones they would want to exterminate. The easiest way to start would be to wipe out all of the people who refused to vaccinate for the Covid and then release something that if you didn't get the first vaccination it would kill with 100% efficiency all those stubborn radicals for good. They would then be left with the slave population they need without the rebellious free thinkers and truth seekers to deal with in the future. Just a thought.
