Scientists are rethinking the immune effects of SARS-CoV-2

Uh oh. We don't even understand "long COVID" yet.

There's clearly a long-term aftermath, but it's not well understood. There are other diseases where that occurs, despite the initial infection seeming to be over. Chickenpox as a child can turn into shingles as an adult.[1] The virus is never completely cleared.

[1] https://health.clevelandclinic.org/can-you-get-shingles-if-y...

timr•39m ago
Please stop making this comparison. There's a clear reason why chickenpox can re-emerge as shingles later in life - herpesvirus maintains a circular chromosome within the nerve cells. It's a known feature of the virus family, and it's detectable [1].

There's absolutely no reason to believe that SARS-CoV2 has similar capability, and those who cling to this hypothesis are engaging in pseudoscience. Viruses are not so complex that we would trivially overlook a feature that would literally change the phylogenetic classification in a dramatic way.

> Viruses are not so complex that we would trivially overlook a feature that would literally change the phylogenetic classification in a dramatic way.

You might think that, but in the past two decades theres been so many "how did we miss that?" in so many fields. I'll let field experts bring specifics up- I only know popularized examples like Roman Concrete. And the ever-easy Mars unit-conversion error.

You can speculate if you like, but the claim you're advancing is fantastical to anyone who has studied virology, and requires an accordingly fantastic level of supporting evidence.

HIV 10 years later turns into AIDs. Immune disruptions are especially scary because without an immune system the constant bombardment the human body is under from viruses, bacteria and fungi overwhelms us quickly.

Finding Covid viral fragments in people long after the infection is very concerning, we don't know how its staying in the body or where but it seems likely its persisting.

Measles, too: https://arstechnica.com/health/2025/09/child-dies-of-horrify...

Malaria is not a virus. It's caused by a eukaryotic microorganism.
ChrisMarshallNY•17m ago
I know. I guess that I should have mentioned that.

However, from the article, it seems that they believe that COVID just whacks the immune system, in general, so everyone gets to belly up to the bar.

Just to be clear: "they", in this case, is a cherry-picked sample of scientists by a journalist.
ChrisMarshallNY•13m ago
I think that's pretty much always the case, these days. Shouldn't be a problem, finding a cherry-picked sample to refute it.

Rebutting this kind of stuff turns into a link-sharing competition. For any debated theory I can show you a thousand links saying the opposite of whatever claim is being advanced, but you'll just assume my links are self-selected.

Look at the content of the article. Literally every quote in this piece is some scientist speculating. That's completely fine, and what scientists do, but the "journalist" is spinning it into a narrative of "scientists believe X", which is both true (some scientists can be found to support literally any claim), and misleadingly over-confident.

It's fascinating how unscientific ideas take root, because people want to believe. On the face of it, the idea of "immunity debt" is preposterous, yet it was amplified across the media -- perhaps because it was a convenient explanation that required no action from anyone.

As i heard recently. Severe acute respiratory syndrome.

Something acute is severe by definition, but without the S we'd all be talking about ARS, so they added the Severe

fluidcruft•32m ago
I don't know what you are talking about definitions-wise here. Things can definitely be accute and not severe. This is easily resolved by looking at a dictionary.
rzzzt•31m ago
"acute" is paired with "chronic" and indicates onset, not severity.

Its important to note that Immunity debt is a concept that anti lockdown activists created in 2020. It was not in medical texts before that point, it never had any science behind it. It was a political term used to end mitigations against Covid not a scientific fact.

There is no rethinking here from serious science (The BMJ is a really bad journal and one of the ones that supported this garbage), the science on infections has been clear for decades, every infection damages us. Covid especially so it damages the immune system directly suppressing CD4 and 8 T cells, B cells and other aspects. Its not a subtle change, in Long Covid research its become increasingly hard to find controls, many people without symptoms show the same blood based markers of immune dysruption and cognitive slowing.

No. It's a hypothesis, because nobody had any explanation for why flu "disappeared". You may not prefer that particular hypothesis, but that does not make it unscientific or political.

In fact, doing what you're doing right now -- trying to present the hypothesis as activism in order to remove it from the realm of reasonable discussion -- is inherently political.

> Covid especially so it damages the immune system directly suppressing CD4 and 8 T cells, B cells and other aspects.

There is no good evidence for this claim. We have robust T- and B-cell mediated immunity to prior Covid infection, and there are now hundreds, if not thousands of papers showing it. Please stop.

The general origin of this meme is the article linked in the piece, which, if you read the abstract you'll see is making a very limited claim, and cannot be used to support the notion that "Covid damages the immune system" in any long-term sense, particularly when we know the opposite is true from many, many other studies:
