If it effects other body systems, the vax certainly affects the brain, which was probably the major goal if one survived. We’ve heard plenty about it coupled with 5G. They already detuned music frequencies to make us irritable and sick, and were using subliminal messaging in music to deter shoplifting in the 70’s. Of course they’re trying to hack and hijack everyone’s brain. At least Neuralink is obvious, unlike the crap the .gov has been doing.
I don’t put anything past this government to get us to do what they want us to do. They have been experimenting with this type of thing for decades.
I suspect a lot of people will “lose their minds” once they figure out what they have done to themselves.
