So who's behind this 50-60+ year old, world-wide conspiracy? You know, involving tens of thousands of people, most of whom have never met or even aware of? Is it a hive-mind of some sort, to coordinate their actions? Because that's the only way your claim works.
But we've not even tackled the bigger question; why? There is no gain here. No money to be made, no power to obtain by doing this. There simply isn't an end-goal that would give you any kind of profit after the trillions of dollars spent on the research, production, distribution & administration of vaccines. Economically speaking vaccines are always a significant loss for the people doing it especially when you factor in the secondry requirements, like shipping it around the world or printing the pamphlets and such.
There's simply too much happening. It can't be done, and it certainly can't be done over decades, long after the first people involved have died.
