2 or more mRNA shots for COVID and you trigger the production of IgG4

Bret Weinstein: "The result that is now replicated that says two or more mRNA shots for COVID and you trigger the production of IgG4. Now that's gonna be a lot of steps for most people. But let me make it simple. Ig means immunoglobulin, it means antibody. IgG is one of the regular classes of antibody. IgG4 is a very special subtype of IgG. IgG4's purpose, its biological purpose, the reason it evolved is to turn down immune responses when they are causing harm, right? When your allergist is trying to cure an allergy by injecting stuff into you, you're trying to trigger this attenuation signal to turn your immune response down.
So we are now giving people multiple shots when we know very well that multiple shots trigger the production of IgG4. Now, one, if you're in the business of trying to create immunity to COVID and the mechanism you've chosen, if this was a surprise to you and you suddenly discover you're producing an attenuation signal, the answer is, oh, what don't we know? Okay, this did not work. It may be working in reverse. You're sending a tank and saying, you know what, if we keep, we're literally tearing the armor off of the tank now, and so it's not protect, like you are doing the opposite of what your goal was. Right. And so, you know, Heather and I have a catchphrase, which is welcome to complex systems, right? You make an intervention that seems like a reasonable thing and some consequence you did not see coming has popped up. Welcome to complex systems. You didn't expect that to happen. Well, in this case, it did happen. That should have caused a total rethink of this if this was an honest effort to improve human health and immunity to COVID. Didn't cause a hiccup at all. So what are we doing?"
