Quick thread on another reason why I don't trust Vinay Prasad.



I'm an immunologist, and one of the main reasons I first came to Twitter 4 years ago was to debunk vaccine denialism.



2/V

To be blunt, I know more about immunology and vaccines than Prasad. This is not his field of expertise.

The study he cites does not support the claim he made:
science.sciencemag.org/content/371/65…

And the John Snow memo is pretty good:



3/V

There were good reasons for thinking COVID-19 vaccines would induce a better immune response than infection.

I was not the first to point this out (h/t @drjenndowd).




4/V

So I responded to Prasad's thread by going over some of the reasons he was wrong.

In reply, he blocked me, without addressing what I said. He's fairly notorious for blocking to evade criticism.





5/V

So let's check some recent evidence on immune responses to SARS-CoV-2 vaccines vs. infection.




page 32:
medrxiv.org/content/10.110…

page 24:
fda.gov/media/144246/d…
6/V

More evidence on immune responses to SARS-CoV-2 vaccines vs. infection:



figure 1C, and:
"[...] post-vaccination neutralization titers were equal to or exceeded the titers found in the high responder convalescent group"
medrxiv.org/content/10.110…
7/V

FYI:

Neutralizing antibodies bind to SARS-CoV-2 to prevent it from infecting cells.
Vaccines can not only increase them more initially without infection, but also increase them after infection.



biorxiv.org/content/10.110…

science.sciencemag.org/content/early/…
8/V

So @VPrasadMDMPH's claim on vaccines failed.

Maybe he should spend more time honestly listening to criticism, as opposed:
- to running from it
- sub-tweeting his critics
- messing up more on COVID-19 vaccines for kids?



9/V

FYI:

Saying 'infection is better than vaccination' is a standard trope of vaccine denialism, as is peddling anti-vaxxers' misleading/false tropes while claiming to be pro-vaccine.
Let's not fall for it.


10/V

Twitter's blocking part 6/V for some reason.

So here's the information in it:

@luckytran Bhattacharya' NIH nomination for 2025 is reminiscent of Scott Pruitt's EPA nomination for 2017:

Position a contrarian ideologue whose views contradict published evidence + expert assessments.

@luckytran Re: "Bhattacharya has spread disinformation on COVID"

You may want to support this claim, if you haven't already.

There are plenty of examples of him spreading misinformation.

For instance: on masking

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.

No mention of the misinformation she + other contrarians promoted, and which conflicted with knowledge advances by experts.

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.

Jefferson + Heneghan don't like the papers.

Makes sense they wouldn't given their track record, especially Jefferson on the Cochrane mask review he led.
