From none other than the Rockefeller Institute. Looking through the linked article and study, you can see that in January of 1918 subjects at Fort Riley Kansas were injected with an experimental "vaccine", for bacterial meningitis. In March of 1918 the first reports of the "Spanish Flu" came out of.. Fort Riley Kansas.
And used by the Cock Sucking Marxist scumbags in all of Western academia, medicine, and politics to push Communism on the world. The Left Shysters were more abundant and rabid then, than they are now.
Back then it was easy to kill an agitating marxist scumbag getting all BLM or ANTIFA In your face, as the law had your back 100% when it came to defending yourself. The first batch of commies that tried to turn the west, did themselves in because they were unhinged maniacs and got their asses handed to them.
The democidal and genocidal fantasies of these elites have been around for a long time. The slave population is a necessary but irritatingly fecund group of cattle to them. They can't stand that modern populations can travel, receive good education, stay literate and informed, crowd into their good restaurants and resorts, and figure things out. They want an elite strata who have all resources and education, a narrow technical underclass, with the rest of the working population ignorant, dependent on crumbs, and periodically murdered down to manageable proportions.
The Spanish Flu was the first huge mass homicide successfully perpetrated under guise of programmed contagion and they got away with it. It seems that is why they have been plotting and planning with diseases ever since.
Keep in mind that the NIH letter release detailed a Gain of Function experiment that was performed on MERS (35% fatality(90 times that of Covid)) to add Covid spike proteins to make it more infectious and able to be airborne. The hammer has been created. When will it be used? Best projection is when the Covid vax has been pushed as far as possible. Then the drones will be released to spread to GMO MERS and the dying will commence.
