“Where do people get these crackpot theories from?”
We’ve known for months that the “vaxes” often negatively impact (sometimes destroy) a person’s immune system. The problem was “acquired” via the shot. Ergo, it is an acquired immune deficiency. So it technically is AIDS, it’s just that some people can’t see the logic and/or don’t know what the acronym stands for.
We've known no such thing.
Waning vaccine effectiveness says nothing about the viability of our immune systems.
