There's a theory like that floating around and it goes like this: the current COVID vaccines are leaky vaccines, meaning they stop symptoms, but not the spread of the virus. This is already occurring. There was a story about an entire nursing home that was vaccinated and still had an outbreak.By extension, sometimes I wonder if Globohomo Inc's next move is to unleash a killer disease that kills everyone who isn't injected with Coovid syrup. Just imagine the double efficacy of this: you kill all the people most likely to resist you without firing a shot, and instill fear in the population ensuring everyone else is obedient to demands to get vaccinated. Only after that do you unleash your super-virus to kill off 30% of the population or whatever, and have free reign to play God and manipulate population and demographics to your whims.
Previous examples show that once a leaky vaccine is introduced into a population, the virus mutates to become more lethal (research the Marek vaccine). Once the virus reaches a certain level of lethality, anyone that isn't vaccinated just dies from the virus.
I think the goal is to mutate COVID into a lethal virus, which gives you two options: take the jab or die. The jab will be on a regular schedule. The elites will design the vaccine so that one batch will be designed to sterilize the population. The elites will, of course, have the correct vaccine for that year, so it won't impact them. Once the general population realizes that the particular vaccine had sterilized them, it would be too late. The media will claim it was faulty, or, my bet: it was tampered with by white supremacists. In any case, the vaccine companies will not have to worry because they have liability protection, and by that point, the population will be so controlled that any dissident voices will have been killed or sent to the now created COVID camps (the camps were created because now the virus has a 100% lethality rate).
I once read that the society in 1984 was supposed to have lasted for 9000 years before the events of that book. I think we are going to be heading to something similar.
