1/10 This shouldn't even be a debate. Who could argue against this? Knowledge is the ultimate public good, & to restrict access to scientific papers to those at academic institutions w/subscriptions to journals is a crime.
2/10 Out-of-control, continually strengthening copyright & patent laws are an economic weapon wielded by the rich against the poor and by enormous, monopolistic firms against small firms. This is a major driver of inequality that receives scant attention.

3/10 The alleged justification for strong IP laws is that they incentivize & facilitate innovation. But as @DeanBaker13 points out in his indispensable (& free) book Rigged, in their current form, IP protections greatly impede innovation. See Ch. 5 deanbaker.net/books/rigged.h…
4/10 How much has medical progress been stifled by the patent-driven secrecy under which private research is cloaked? And by the gross distortions that drive companies to pursue expensive, patentable treatments & ignore cheap, often greatly superior treatments? (Rigged, Ch. 5)
5/10 Apart from the baleful economic & scientific effects of our IP laws, it's worth considering some more indirect effects these laws have on public health. Patent monopolies unquestionable cause corruption in the pharmaceutical industry. @DeanBaker13 on the opioid crisis:
6/10 Understandably, the rampant corruptions & recurrent scandals in the pharma industry have led to public distrust. Skepticism about Big Pharma claims is of course justified, but it has led some to reject anything connected to pharma, including vaccines. statnews.com/2019/02/26/ant…
7/10 The anti-vaccine movement's claims are of course absurd & tremendously harmful to public health, but their outright rejection of all scientific evidence largely stems from the never-ending flow of pharma-industry scandals, which are a predictable result of patent monopolies.
8/10 There's been much discussion of how to combat misinformation during the pandemic, but little talk of one of the root causes: patent-monopolies. Public financing of drug research could eliminate patent monopolies & allow drugs to be sold at generic, free-market prices.
9/10 Until we reform our rotten, corrupt, patent-monopoly-driven pharma industry, public skepticism of even impeccable medical research will remain, and such distrust will continue to be exploited by charlatans & mountebanks peddling noxious nonsense, w/grave public consequences.
10/10 Chart in tweet #8 is from chapter 5 of @DeanBaker13's book 'Rigged.' The book is freely available in digital form, & an awesome intro into some of the most pressing economic issues of our time. Definitely give Ch. 5 a read if nothing else. deanbaker.net/books/rigged.h…

So it's clear that BA.3.2 preferentially infects children, something we have never seen before in a SARS-CoV-2 variant.

Why?

The question's baffled me, but after a suggestion from Darren Martin, I think I have an explanation that makes sense.
1/16
I've tried to make sense of BA.3.2's penchant for kids by considering its unique spike: more compact, more closed, & more antibody-evasive than any other variant.

But I think another feature of BA.3.2 is responsible: its wholesale deletion of ORF7a, ORF7b, & ORF8 (∆ORF78).
2/
∆ORF78 is rare but not unheard of; it was in several late XBB variants (GW.5.1.1, FW.1.1, GE.1.2, etc) & a few branches of other variants. I've long thought these late XBB had an advantage in some population subsector, but I didn't suspect kids.

You have to wonder for how long we will continue seeing infections from 2020 continue to show up (in absurdly high quantities) in wastewater.
1/16
I suspect that the number of people continuously infected since 2020 or 2021 is much larger than we realize. It's impossible to prove, but there are case studies where a chronically infected person gets infected by a new variant, which drives out the original virus...
2/16
...which consequently leaves no trace that the person was chronically infected before the super-infecting variant—took over.

Why then are some Cryptic WW variants resistant to being outcompeted by newer variants?

While the final outcome for BA.3.2 is uncertain, its unique characteristics—extensively remodeled spike NTD & SD1/SD2, novel S2 muts, & total deletion of ORF7a/7b/8—make it the best candidate for co-dominance we've seen, which could mark a new era in SARS-2 evolution. 1/
Until now, the broad pattern of SARS-2 evolution has been:

1) Emergence of a saltation variant originating in a chronic infection

2) Rapid growth/global dominance & a variant-driven wave of infection—especially if it emerges in late fall/winter (BA.1, XBB.1.5, JN.1). 2/
3) Stepwise evolution over the next few months/years, usually without driving major waves (the JN.1-descended KP.3.1.1 being a notable exception).

4) Repeat

Very proud to be a co-author on this comprehensive preprint on the novel, growing saltation lineage BA.3.2, together with @Tuliodna, Darren Martin, Dikeledi Kekana, and lead author @graemedor. 1/9
I would normally write a summary 🧵 of the BA.3.2 mutational analysis here, but as much of my contribution parallels my previous BA.3.2 threads I'll just link to those here, w/brief descriptions of each.

This is my first, big-picture BA.3.2 🧵. 2/9
Short thread from June when the first travel BA.3.2 sequences showed up. I think my prediction from back then has pretty much been borne out. 3/9

BA.3.2 emerged in Nov 2024 after ~3 years of intrahost evolution with >50 new spike AA muts, but since then, it's changed very little. Could the drug molnupiravir (MOV) galvanize BA.3.2 into pursuing new evolutionary paths? A new 89-mut MOV BA.3.2 seq suggests it could. 1/11 Image
Background on MOV: It's a mutagenic drug. Its purpose is to cause so many mutations that the virus becomes unviable & is cleared. But we've long known this often does not happen. Instead, the virus persists in highly mutated form & can be transmitted. 2/
I was an author on a paper published in @Nature that conclusively showed not only that MOV has created highly mutated, persistent viruses, but that these viruses have transmitted numerous times. See 🧵 below by lead author @theosanderson. 3/

The most valuable viral research tools—@nextstrain & CovSpectrum—are being destroyed, not only blocked from new data but now forbidden from even sharing info from the PAST. Why?

Because GISAID is run dictatorially by a con man, paranoid egomaniac, & liar named Peter Bogner. 1/
I use CovSpectrum & Nextstrain every day—& I'm not the only one. Every Covid thread I've ever posted here has relied partly on CovSpectrum & Nextstrain for information & visuals. These vital tools have now been stolen from us by a world-class grifter. 2/ thinkglobalhealth.org/article/to-fin…Image
For years scientists knew something was very, very wrong with GISAID, but the breakout story (from which much of this 🧵is based) came 2 years ago in @ScienceMagazine from @sciencecohen & Martin Enserik. 3/
