“The human immune system is a thing of wonder. What it does is when it faces a new pathogen like this, you’ve got professional cells, they’re called professional antigen-presenting cells —they’re kind of rough tough things that tend not to succumb to viruses. And their job is to grab foreign things in the near environment and tear them limb from limb [inside the cell]. They really cut them up into hundreds of pieces.
And then they present these pieces on the surfaces of their cell to other bits of your immune system, and amazingly, because of the variability that God and nature gave you, huge variability to recognize foreign things, and your body ends up using 15 to 20 different specific motifs that it spots about this virus. They’re called epitopes, basically they’re just like little photographs of the details about this virus. That’s what they do. And that is what is called your repertoire, your immune repertoire is like 20 different accurate photographs, close-ups, of different bits of this virus.
“Now, if a tiny piece of the virus changes, like the .3% I’ve just described, if you are reinfected by that variant, your professional cells tear into that virus and cut it into pieces, present them again, and lo and behold, most of the pieces that you have already seen and recognized, are still there in the variants.
“There is absolutely no chance that all of them will fail to be recognized and that is what is required for immune escape, to escape your immunity. It must present to you as a new pathogen. It must be sufficiently different that, when it is cut up by your professional checker cells, it won’t find mostly the same thing it has seen before. And that is just absurdly impossible when you have only varied .3%, so it is 99.7% (similar).
“And before them, coming from my theoretical understanding of multi-locus immunity, which is what I just badly tried to describe, to what actually happens … If your [immune system] is presented with something that contains even half of those similar pieces, there is no way your body will say, ‘that’s a new pathogen.’
“And, so, the idea that 0.3% could even have a chance of getting around immunity is just a lie. It’s not [even] like an opinion difference.
