I recently got a copy of Dr. Judith Curry's book without buying it myself.

Looking over it confirmed to me that it's largely misinformation.

I'll illustrate that by assessing its claims on COVID-19.



"11.3.1 COVID-19"

To reiterate: Curry draws parallels between COVID-19 + climate change.

But some of the sources she cites suggest an ideologically convenient narrative misinformed her.

That becomes clearer when assessing her claims.

Dr. Judith Curry recommends people read at least the 45-page preview of her new book.

I did.

It's bad enough I wouldn't recommend buying the book.
It's largely contrarian conspiracist misinformation.

Many reviews laud the book without addressing whether her claims are accurate, likely because she ways what they want to hear.

A reminder, since there's a resurgence in Musk + right-wing politicians trying to score political points by saying they want Fauci prosecuted:

Musk's dislike of Fauci drove him to post an easily debunked lie (57/E, 56/, 41/)

Still no apology from Musk for falsely smearing Grady based on untrue things he was told, or that he made up.

No, neither chloroquine nor hydroxychloroquine worked for SARS-CoV-2.

Fortunately, Fauci recommended neither in March 2020.

Thread on a myth Jay Bhattacharya (@DrJBhattacharya) continues to peddle to undermine confidence in public health agencies and to suit his policy agenda.

The myth may undermine responses to future public health emergencies.

Some background:

The infection fatality rate (IFR) states the proportion of *SARS-CoV-2-infected* people who die of the disease COVID-19.

The case fatality rate (CFR) states the proportion of *reported cases* who die of COVID-19.

Wanted to address some exaggerations of a recent paper co-authored by Martin Makary.

"Prevalence and durability of SARS-CoV-2 antibodies among unvaccinated US adults by history of COVID-19"
jamanetwork.com/journals/jama/…


Image 2/U

The paper shows that various non-vaccinated people had antibodies against SARS-CoV-2's RBD (receptor-binding domain) up to 20 months after infection.

Let's set aside the obvious issue of whether those people were re-infected within those 20 months.

By deleting tweets in which one made false claims, one can present oneself as a "centrist" on COVID-19, while painting one's critics are "extremists".

Some illustrations of why that strategy won't work on sensible people.


2/B

Some basics:

- CFR: case fatality rate, or the proportion of *reported cases* who die of the infection
- IFR: infection fatality rate, or the proportion of *infected people* who die of the infection

A common vaccine denialist talking point is that vaccines might have hidden long-terms effects that don't shown up in the time-frame of typical clinical trials.

OK.

Name such a side effect.

Options that are off the table:

Usual warning, since hopium dealers will not explain this:

The anti-nucleocapsid assay used in this Gauteng seroprevalence study is prone to seroreversion. So the study would under-estimate prior infections in vaccinated people.

This has been known for over half a year.

This thread will first address why the paper doesn't support the contrarian/denialist claims people made about cross-reactive T cells.

The conclusion of the article below has become popular among some. So this thread will address it.





"Protective immunity after recovery from SARS-CoV-2 infection"

Some context:

The central (thought not only) point of vaccine mandates is to limit transmission. So in this thread I'll largely ignore the benefits vaccines provide to the person vaccinated, + instead focus on protection of those around them.

@TheEliKlein is a denialist + COVID-19 contrarian who's been spreading nonsense for over a year. Unfortunately, CNN recently gave him a platform.

So this thread will expose some of his nonsense, while reviewing some biology relevant to COVID-19.

2/E

Some context 1st, so folks can recognize grifters like him in the future.

He ideologically opposes various policies that limit SARS-CoV-2 transmission (ex: lockdowns). That benefits him financially since it gets people to his art dealing business.

For Gupta's non-expert apologists:

I'm an immunologist, so Gupta does not know more than me about topics like herd immunity, antibodies, seroprevalence, etc.

John Ioannidis has a new paper on COVID-19.

He illegitimately downplays the number of COVID-19 deaths, which suits the narrative of those who downplay COVID-19's severity to undermine policies they dislike.

So... a thread.



link.springer.com/article/10.100… 2/U

Since at least March 2020, Ioannidis downplayed the pandemic's severity by, for example, falsely claiming SARS-CoV-2 has a fatality rate comparable to seasonal influenza.

That justifiably annoyed folks.

One of the leading SARS-CoV-2 lab conspiracy theorists from DRASTIC, @TheSeeker268, has a new article. I want to focus on its discussion of miners since it shows how ridiculous conspiracists can be.

Like many other aspects of lab leak conspiracy theories, the miners point was debunked for a year or more. But conspiracists peddle it anyway, hoping people are uninformed, or paranoid, or... enough to fall for it.

On other threads I criticized estimates of COVID-19's fatality. Here I'll highlight the best estimate I've seen:
0.9% from Neil Ferguson's team at Imperial College.

It's being falsely criticized again.

Ideologues often criticize the 0.9% estimate in order to downplay the severity of COVID-19 + evade policies they dislike. John Ioannidis resorted to that
