Since 2020 I have claimed that sars cov 2 infection would create harmed t cell memory based on phenotypes after infection

It is now proven

Even so, I have several Professors who pretend to not understand or do not understand how, nipping at my heels

I assume they behave this way because they are tenured & very mad, so they feel they can put their ignorance and vitriol on display wantonly

Bertoletti even made a nod to me in a publication, which the journal maintains references me in no way whatsoever

For their benefit, I will list the publications that prove my thesis correct:

The first is how T cell responses derived from vaccination are superior to those derived from infection. T cell functions after infection were harmed. The publication is below:
The second proof is how people who were infected risked reinfection shortly afterward. That publication is here:


Image
This is consistent with the third publication, which shows the dampened CD8 T cell responses following infection. That publication is here:
Image
To address Kasper's category error: faster pcr negativity of a sars cov 2 infection upon reinfection is not proof that T cells or immunity have not been harmed.

Antibodies and b cell memory are largely contributing to clearance as well

You can look at t cells directly Image
The paper from the Danish Government is extremely poor and political

It claims people infected with cov 2 have less chance of infections with other illnesses, despite confessing how this is unexpected given derangements in the immune system following infection
Image
Image
It also fails to repeat observed increases in other infections like tonsillitis after sars cov 2, which is another weakness this paper acknowledges

It is very poorly designed Image
In fact, we know a common post-viral complication is a bacterial pneumonia

The study could not reveal this, and in fact showed the opposite; that sars cov 2 protects

How could any conclusions be reliably drawn from the paper? It is poor science on parade. Image
It is not the only poorly designed paper

Some epidemiology studies have been designed where they sample a population biased by some metric, including age or working status

They are massaging the epidemiology

1) Senior immunologists said I was wrong that infections posed the risk of widespread T cell exhaustion and called it "twitter nonsense"

2) They said I was wrong that the experience in severe disease shared the spectrum of mild disease, despite sharing mechanism
3) They said I was wrong about Fas-mediated apoptosis

4) They said I was wrong that reinfections would continue to hyperactivate T cells

5) They said I was wrong about the prospect of rapid evolution and antigenic escape
6) They said I was wrong that ace2 affinity would increase after Omicron

7) They said I was wrong that covid harmed the immune system

8) They said I was wrong that immune dysregulation underlies Long Covid

The virus has not turned into an ordinary illness

Symptoms are from the immune response and appreciated grossly (eg cough, chills, headache, fever)

Pathophysiology tells a different tale of effects Cov2 has that ordinary illnesses don't

🧵
For example, even extreme lethal cases of flu do not send T cells into the brain

SARS Cov 2 does

Scientists examined T and B cell changes after infection with normal viruses versus covid.

Only Covid, not the normal viruses, caused missing unactivated naive T and B cells Image

The claim Long Covid rates would reduce upon reinfections were made by Iwasaki, Zeynep, and others

When I said I believed the opposite I was derided and mocked

Three studies now show increasing rates of Long Covid on reinfection

🧵

ImageImageImageImage
I was mocked as not a subject matter expert by the established in the field like Rupert Beale. Zeynep would tag 15+ immunologists below me

Before I was mocked as "not Galileo" because I claimed there would be no herd immunity to Covid before Omicron
Image
It’s strange that experts went on record saying reinfections would result in lower rates of Covid

I would have to reduce the considerations of what creates long Covid into a maybe 12 kB string of thought in order to make the same conclusion

Hello

I am the only person who said there would likely be increased rather than decreased rates of long covid upon reinfection due to cumulative effects on the immune system and organs

Several studies recently corroborated this
Recently, I made a statement that lifetime rates of long Covid would be over 99.9%.

Most people erroneously took this as a Percentage of the population affected, which it would not be

Some people would get long Covid several times others, not at all
This is easy to understand, however, some people that do not understand it have very strong opinions

This led me to realise that in instances where precise language and proper conceptualization are necessary, especially when things are counterintuitive, one will stand outside

Both Ladhani's and the NIH's Long Covid studies show the idea that Long Covid probability goes down with reinfection because your "immune system fortifies with exposure" is false

This was yet another piece of wishful thinking that I stood against

You may remember when reinfections were claimed unlikely, and immunity would be lifelong similar to SARS 1

I claimed it was possible sars2 would mutate quickly out of it

This is yet another example of being overly optimistic and not accounting for facets of sars cov2

2/7
This presents a great challenge to society and its people at large

With similar rates of LC between infection and reinfection, the tally of people too ill to work steadily increases

What it means for you is that it could be more likely than not that you get Long Covid soon

All throughout medical school, I have faced Marc Veldhoen and Bertoletti calling me things from "depressed" to "grifter," and mocking me for stating that SARS Cov 2 infection can cause T cell harm

Here Zeynep Tufekci acknowledges the article is pointed at my "looney" theories ImageImageImageImage
If the investigation finds that the "fit and happy" title has nothing to do with a directed critique against me, it will have been a sham ImageImageImageImage
I cannot get more from Veldhoen's account as he made it private, but he had Xs on my posts calling me a grifter
