Two new high-profile studies add to the increasingly worrisome picture of how even mild cases of COVID-19 can have detrimental effects on brain health.
From the article:
"....two new studies published in the New England Journal of Medicine shed further light on the profound toll of COVID-19 on cognitive health." And in other studies cases "with mild to moderate COVID-19 showed significant prolonged inflammation of the brain and changes that are commensurate with seven years of brain aging."
What specifically are they finding to say covid was found in the brain? Can they tell the difference between covid vs vaccine in whatever they find?
I have a Facebook "friend" running the "they found vaccine spike proteins in the brain" line, and "they said it would only stay in the deltoids". I'm imagining he confused the "vaccine should stay in the muscle" as opposed to the spike protein which I could see traveling with blood. As for finding it in the brain or heart, could we tell the difference? Would we?
Sure... but the "friend" is regurgitating that it's specifically the spike protein that was found in these areas. I can find plenty of articles about finding the spike protein in various parts of the body cause that happens with catching covid. I haven't found an article saying they've found spike proteins associated with the vaccine specifically. This is nowhere near convincing enough for him cause the evil gubment could suppress that or some stupid bullshit.
He also pushed the claim the infamous "they" said the "spike protein wouldn't leave the delts". For this I imagine it was the vaccine itself that wouldn't leave the muscle but that says nothing of the spike proteins induced by the vaccine.
So the overarching questions are of they can actually tell the difference in the spike proteins found in other parts of the body? If that's possible, is that something employed? I could see it being possible, but maybe not done normally for reasons (too expensive to just test for every time or no need to tell the difference). And lastly, was the claim ever pushed that the spike proteins in response to the vaccine wouldn't leave the arm/delt/muscle?
Regarding covid spike proteins: covid itself does have a very prominent and distinctive spike protein.
Most (possibly all) of the covid vaccines have used qualities of the spike protein to 'describe' covid to your body, so that your body knows to respond aggressively tow covid infection. Once the body is aware of the threat from covid (either through a vaccine or actually getting covid), it makes antibodies against a future covid infection.
Finding covid's spike protein in someone means that they currently have or are recovering from a covid infection. Finding covid's spike protein in someone does not mean anything about their vaccination status.
Finding antibodies to covid's spike protein in someone means that their body has been trained to react aggressively against covid. This could have happened because they got covid, or were vaccinated, or both.
Though none of them are quite as distinctive as the spike protein, covid does have other proteins in it as well - for example, it has a fairly stable nucleocapsid protein. And if you get a covid infection, your body will produce antibodies to covid's nucleocapsid protein.
So far (at least that I'm aware of) there are no covid vaccines focused around the nucleocapsid protein, which would also make the body produce covid nucleocapsid antibodies. So if you find nucleocapsid antibodies in someone, that person has had a covid infection. The antibodies fade over time, so their infection was probably within the past year or so.
And finally, the vaccine is injected into your arm. The vaccine stays in your arm. Your body 'looks' at the vaccine, sees it as a threat, and produces antibodies that spread throughout your body. Which is what we want it to do - after all, what use would a vaccine be if it only worked in one square inch of your shoulder?
To summarize: Finding covid spike proteins means a covid infection has recently happened. Finding covid spike antibodies means the body has been infected, vaccinated, or both. Finding covid nucleocapsid antibodies means that a covid infection has happened within (roughly) the past year. And the vaccine stays in the shoulder; the antibodies the body makes in response to the vaccine spread throughout the body.
Finding covid's spike protein in someone means that they currently have or are recovering from a covid infection. Finding covid's spike protein in someone does not mean anything about their vaccination status.
So a recently vaxxed person that's never had covid would not have any trace of a spike protein?
If that's what you're saying I'd love a source. The "friend" prolly won't read it, but I'll at least peruse it and file it away for the inevitable next time he drops this claim.
