You are arguing that the actual spike protein and the synthetic genetically engineered protein from the Pfizer modified RNA are significantly different, but close enough for immunity. That is a pretty narrow slot.
You do agree that the native spike protein is inflammatory, right?
Also, I don’t think you are stating that the native virus has a pass-key like entry into any cell, as the modified RNA with the lipid coat in the Pfizer injection has.
Are you? (That would be really silly.)
Later...
Please don't misunderstand me. I am NOT trying to convince you of anything. I will try to get things out of you by trying to poke holes in your arguments, nothing personal with you or anybody else. Usually something will surface sometimes unintended. From you I got another good read, Khan et al., on the inflammatory effect of the spike protein, (Thanks!) and an interesting thought on the immune response to the vaxx s1 in the brain. There is a line of inquiry there that will apply to the risk of post vaxx ITP in all the vaccines. (Interesting)
If there is anything else you would like to help me with then please state it directly. I am on to other things for now.
