Given that the major COVID-19 vaccines had a significant protective effect against Long COVID, this is a particularly perverse variation on the conspiracy theory. Long COVID is much more prevalent among people who’ve experienced severe COVID symptoms, and unvaccinated people have the most severe symptoms. One doesn’t need a PhD to do the math here.

"yes" ...

Australian studies show a protective effect (in that the fewer people that got COVID (correlated with vaccines) the fewer got Long COVID)

See Page 8: https://www.aihw.gov.au/getmedia/9592f439-9b96-4589-a55d-6b0... (2022)

Australian studies in W.Australia also show:

  In multivariable analyses, pre-existing health conditions at the time of initial SARS-CoV-2 infection and reporting fatigue, shortness of breath, and cough 3 months post-infection were independent predictors of persistent long COVID.

  Age, sex, and number of COVID vaccinations were not significantly associated with persistent long COVID.
which needs to be qualified with an "of course" as W.Australia (3xsize of Texas, small population) was isolated from the world and then almost the entire state got two to three rounds of vaccination at much the same time:

That's because vaccine does not cause autoimmune disorders

Oh sorry, the last one shows that covid increases the likelihood to develop autoimmune disorders.

Sadly, no mention of Mast Cell Activation Syndrome, or even mast cells at all

This is a blog on the root cause. MCAS would be an intermediate mechanism in making you feel sick, but something must have triggered the MCAS. Thats the autoimmune response.

It'd have been interesting for them to discuss it, but from what I understand it looks like MCAS is probably an entirely separate thing (that can also be triggered by COVID), but because of the overlap in symptoms, many people who assumed they have long COVID actually had MCAS. And even after teasing those two out, there may be more conditions in the long COVID bucket.

And of course people can have both.

I caught this in the Dec 2023/Jan 2024 Covid wave, in a densely-packed Bay Area tech office. I only returned to near-full mental clarity in Jan 2026 - two years later. It's an insidious illness that needs more visibility. Poorly ventilated offices full of sick colleagues in close proximity are ideal conditions for transmitting airborne diseases, and it's far too easy to develop a debilitating chronic illness this way. There should be minimum clean-air standards for open offices to protect workers.

>implying there is at least a substantial fake element to it.

The article actually argues against that reading: IgG transferred from patients into mice reproduced the symptoms. Mice don't have a nervous disposition. That points to a physical mechanism.
