My NEW op-ed is out in @usnews!
Mandating 12-18 year old kids get 2 doses of COVID19 vaccine & throwing them out of school if they don't is one of the most regressive, dangerous, and misguided policies in recent years, and I condemn it

Some thoughts 🧵
usnews.com/opinion/articl…
1. How can LA mandate 2 doses for boys aged 12 to 22 when our peer nations do not support 2 doses, given risk of myocarditis?

Same science
Same data
Mandate 2 vs. optional 1?
You can't use power of mandate for science that is not settled
2. The current policies are so restrictive that you can't even space the doses out to 12 weeks, as Norway is attempting to lower risk of myocarditis.

Why is there no flexibility in these policies?
3. The former FDA commissioner and Board member of Pfizer, Scott Gottlieb, urges that parents should have some say in when and how to vaccinate kids

What about kids s/p covid w/ natural immunity?

Yet these policies preclude it!
4. Throwing kids out of school for not complying
will mean throwing some of the poorest kids in USA out

After society failed these children by WRONGLY depriving them of a year of school

Shame on us...
Punishing kids in LA is not solution to adult vaccine hesitancy elsewhere
5. This is not like other vaccines
Kids 12 to 15 is under auspices of EUA only
Peer nations are making different choices
Information on safety changes by the day
This is not like other mandates
6. Americans have repeatedly taken out their rage and frustration on children with prolonged school closure, and now this.

When the dust settles our country & this generation is going to be so broken from these actions.

I pray they forgive us; we failed them.
7. I am pro vaccination, and have personally Rx countless vaccines (they are used in post transplant setting)

Also Listen to my 1 hour defense of vaccination

But let me be clear, this policy risks serious harm to these kids.

It is regressive.

honestlypod.com/podcast/episod…
8. I have been a progressive my entire adult life; I believe government can be a powerful force of good if policies & incentives are constructed correctly. I believe society must help the least well off.
The theme of my 2 books.
Sadly, I no longer recognize many progressives.
9. Now this gentleman 👇👇
Anthony LaMesa is a must follow on schools
He consistently understands what progressive policy means, and what putting kids first means

Every single one of these garbage papers use the denominator of PCR+ covid infections, and not the actual denominator of people who had covid-- many do not present to the doc. Every single one of these papers is shit. I would be embarrassed to be an author. Incompetent work. Image
People with covid who are so sick they have to go to the doctor have poorer health than people who don't. That should be in the journal of obvious things. All of these authors are extrapolating beyond the evidence. They're creating a body of trash calling itself science
Is there a single paper that uses a sero prevalence denominator? Is there a single researcher in this field whose brain is working? Just one. That's all I ask for.

Totally wrong. Because Vincent is not thinking about the counterfactual correctly.
*Teachable moment*

1 These drugs were approved by accelerated approval in the LAST line. Some later improved survival & others didn't in an EARLIER line.

2 The counterfactual to AA... 🧵
is demanding RCTs powered for say, OS (survival). If a company couldn't use RR to get AA, they wouldn't run a trial in the 2nd line or 3rd line setting powered for OS, they would run it in the 7th or 8th line

Why? more dire = faster result
3. We have proven that in these v late lines RR and median DOR (the current AA criteria) result just as fast as OS

Many people want covid to be worse than it is. They imagine it has long-term consequences that are worse than other respiratory viruses. Adjusting for severity of illness, it doesn't. Only anosmia is unusual. Why do they want it to be worse than it is? 🧵
For some reason, some people want to live with perennial precautions. They don't want to take off the mask, they want their children to mask, they want to keep getting booster after booster. I don't know why but they want to live in fear.
They have...
A mountain of retrospective observational data that they think supports their claim that covid has long-term disability. That it's a vascular disease. And all sorts of other claims. Nearly all these studies are flawed. They don't have good controls.

I spent a lot of time today reading this paper, the criticism, the rebuttal, the retraction notice. OMG! My head hurts.

But... An important point no one has said is that the entire premise of the study & criticism is flawed. 🧵 Here is a short summary
Lots of prior studies show many psychological findings don't reproduce. Obviously that's because so much of this science is bullshit. Small sample size, weak methods. Entire fields struggling to justify their existence & people p hacking and exaggerating to be on @HiddenBrain
How do you fix this problem? No one really knows. All of academia is incentivized for hype and discovery, actually being a thoughtful student, criticizing things, pushing for better methods that's unpopular.

Thank you @Erman_Akkus for ur reply it is a good learning opportunity for #ESMO24

In 15 tweets, I will summarize the trial, my criticism, and why this reply contains 3 common errors that oncologists make because our training doesn't teach these ideas.

First, the trial... Image
The trial is #LEEP-012 and randomizes pts with INCURABLE (see pic) liver cancer to TACE (embolization) plus costly drugs or embolization alone.

These 2 drugs are TOXIC (lenva is horrible) and cost a FORTUNE 200-300k per annum per person
#ESMO24 Image
Every single person has the cancer return. It is non-metastatic, as @Erman_Akkus says, but it is not curable.

Here is the time until measured lesions grow 20% or new lesions present or the patient dies

That's what he and others are excited by #ESMO24

Just out on @medrxivpreprint and @CityJournal
We analyzed all COVID19 corrections in the @nytimes
We show that 2:1 the Times OVERSOLD covid risk or FALSELY HYPED the benefit of restrictions
1 reporter alone was 7% of all corrections
Let's take a look 🧵Image
Image
Naturally, in times of crisis, newspapers won't get everything right

Corrections are inevitable and forgivable

But corrections should occur at random

Sometimes they are too high and sometimes too low

If they tend to be in one direction...

That's bias
Here is the key figure
When the New York Times made mistake those mistakes were TWICE as likely to OVERSTATE the harm of COVID, particularly to kids, than UNDERSTATE

This is evidence of systematic BIAS in their reporting

But it gets worse Image
