Covid 9/10: Vitamin D

Last week: Covid 9/3: Meet the New CDC

Imagine there is a simple, cheap, safe and effective solution for Covid-19. 

The solution is something known to be safe. It is widely available for reasonable prices. Any patents have long expired. It is something that people need and benefit from anyway. It’s probably worth doing without the pandemic. It just happens to also have a dramatic effect on Covid-19. 

You might think that once the solution was discovered, everyone would shout it from the rooftops. There would rapidly be studies to confirm the solution if it was even considered ethical to not give the solution to everyone. Production would kick into high gear. The pandemic would soon be over. 

Or, if you’ve been paying attention, you might think that our civilization is so dysfunctional, so inadequate, that none of that would happen. That for no particular reason, or for reasons we’ll get into later, the whole thing would end up mostly being ignored. We’d carry on with all the same arguments, all the same deaths, all the same economic devastation, putting all of our lives on hold. 

That the world you would see would not look much different from our own.

That cynical view looks right. 

The solution has quite possibly been found. We were talking about it, including in the rationalist community, back in February.

Everyone’s mostly ignoring it.

The solution we’re talking about, of course, is Vitamin D. 

Are we certain or even highly confident this is the whole ballgame? No. Of course not. 

We’re not a functional enough civilization to figure this one out in half a year. But we are exactly functional enough of a civilization to start to notice this as a potential solution, and to have run one tiny study that showed dramatic results. If it’s not a dramatic real effect, it’s either taxes or fraud, and I don’t think it’s taxes.

So that’s the headline this week.  

I don’t want to oversell this – it’s still possible this is all a false alarm and there’s nothing to see here, because we dropped this ball so utterly that the first study just came in and it’s tiny. But at this point I’d be very surprised if this isn’t, at a bare minimum, a gigantic piece of low hanging fruit.

Here’s the thing. 

I think about the world in which Vitamin D is a huge deal, and eliminating Vitamin D deficiency would make the pandemic harmless enough that we could mostly let it burn. I think about the world in which Vitamin D matters almost not at all, and if we pushed on it we’d be wasting our imperial focus points for nothing but a few less broken bones and other minor assorted benefits to the otherwise deficient. 

Aside from a few study results and statistics, those words look almost identical. People’s behaviors look the same. So even if it turns out D is useless, that in no way lets anyone off the hook.

In the meantime, for those who tl;dr the later sections, please generously supplement Vitamin D until further notice and get others to do so as well. It’s a freeroll with a huge upside.

There’s a few other minor things as well. In other let’s-not-solve-this-problem news are some vaccine and plasma developments. We also have some school related matters to discuss. 

First, let’s run the numbers.

Previous trends continue, with a large dropoff in the West. Labor Day weekend may be part of this, as Tuesday’s count was highly suppressed. If there is a small bounceback next week, it should not be alarming. In any case, slow but relatively steady progress seems to be taking place as expected.

Continued improvement in the South and West. Midwest pulls back a bit from last week’s increase, probably not a sign of a real decline yet. THe Northeast number isn’t great. Overall, a mixed bag.

Positive test rates continue to decline despite slowly dropping test counts. The upside of seeing low test counts is that it means a given percentage of positive tests is less scary and likely reflects less cases, because those who do get tested are on average higher priority. 

Governor Cuomo would often say that test percentages were low despite large numbers of tests, because he’s innumerate and a blowhard. In this clip he says he ‘reopened the whole economy,’ which he didn’t, and he can’t understand why the infection rate has stayed low. It’s ‘inexplicable to the experts.’ They said ‘it’s going to go above 1% and it could get to 2%.’ 

And then what, you moron? You thought it would double one and then stop? As if by magic? What the flying fork? 

In other words, he took actions he expected to lead to the virus to come back, and can’t figure out why it didn’t. Hint. It’s herd immunity plus heterogeneity (new study on that this week!), and people making responsible private choices, you forking idiot. 

Why oh why don’t people trust the experts?

Please. Please. Please. Do not hold this up as an example of a good leader. Do not consider this man for higher office. Being more responsible than the orange man is not the standard.

Again, everything here is as expected. It’s clear that things are improving slowly, and that our testing capacity has leveled off because no one cares to improve it.

Vitamin D As It Ought To Be

What is going on with Vitamin D?

For a long time, we have known that not being deficient in Vitamin D is important. Like many vitamins, if you don’t get enough, it’s not good. A lot of people are deficient. This study from Europe leads the abstract off with this: 

Vitamin D deficiency (serum 25-hydroxyvitamin D (25(OH)D) <50 nmol/L or 20 ng/mL) is common in Europe and the Middle East. It occurs in <20% of the population in Northern Europe, in 30–60% in Western, Southern and Eastern Europe and up to 80% in Middle East countries. Severe deficiency (serum 25(OH)D <30 nmol/L or 12 ng/mL) is found in >10% of Europeans.

There’s a reason they put Vitamin D into the American milk supply. Google says that the American ‘deficiency’ rate, defined as less than 11 nanograms/ML, is around 11%. This study says the rate of ‘deficient’ Vitamin D, which they define as under 50 nanograms/ML, is way higher than that:

According to data collected between 2005 and 2006 by the National Health and Nutrition Examination Survey (NHANES), insufficient vitamin D levels were found in 41.6% of the 4495-individual sample size. Race was identified as a significant risk factor, with African-American adults having the highest prevalence rate of vitamin D deficiency (82.1%, 95% CI, 76.5%-86.5%) followed by Hispanic adults (62.9%; 95% CI, 53.2%-71.7%) [3]. Additional risk factors for vitamin D deficiency that were identified included obesity, lack of college education, and lack of daily milk consumption [3].

(The most relevant threshold for Covid-19, as suggested by correlational studies, is plausibly in the middle between those two, around 30).

As is often the case, even if Covid-19 is not a consideration, we are in need of More Dakka. In theory you can overdose on Vitamin D, but it’s something that can only be done on purpose with extreme supplementation. Quantities as high as 10,000 ICU/day (50k-100k per week) seem to be safe over extended periods.

For a long time, there have been studies trying to show that Vitamin D helps to prevent or treat various conditions. The verdict has mostly been negative. Lots of trials for various things showed that Vitamin D had no effect. A few did show some effects, but we’ve learned to be suspicious that publication bias plus random effects explain such results. When I look at the net result, I see improvement in respiratory infections and in a few other places, with an emphasis on helping those that are deficient. It seems clear to me that there’s substantial benefits to supplementation when deficient, especially severely deficient. It does not seem clear that there is benefit to supplementation for those that are not otherwise deficient. But of course we don’t get outdoors much these days, and in California doing so would be dangerous and probably wouldn’t get you much Vitamin D – the sky is kind of the wrong color. So given the lack of downsides, supplementation seems like a freeroll already, but not a panacea.

The problem is that Vitamin D has been somewhat of a hype magnet. Many, including one person I know, claim it helps with pretty much everything quite a lot and it’s vital to immune response. Which might be true, but the results so far are not encouraging. This makes the Responsible Person headline to not listen to the hype and not get excited, rather than to point out that the odds still favor using it. Which is a pretty good microcosm of many parts of the general Covid-19 situation. 

It’s clear that correlational studies of Vitamin D with disease find a strong link. Those without sufficient Vitamin D are at higher risk of pretty much everything. Hence the checking of Vitamin D as a solution to pretty much everything. 

The going explanation is that causation at least partly runs in the other direction. If you are in poor health, you’re unlikely to get enough Vitamin D. It’s also plausible that those who supplement tend to have already been healthier as well. Old people with limited mobility are especially likely to be deficient. There are other causal pathways as well. 

That’s also the central feature of the skeptical interpretation of Covid-19 results with regard to Vitamin D.

For a while, we’ve had data that suggests Vitamin D deficiency might play a role, potentially a large role, in who dies or gets severe illness from Covid-19 and who recovers. Some examples that were quoted on LessWrong were:

– A study in Indonesia found that out of the patients that died from COVID-19, 98.9% of them were deficient in vitamin D, while only 4% of the patients with sufficient vitamin D died.

-A study of patients in New Orleans found that 84.6% of the COVID-19 patients in the ICU were deficient in Vitamin D while only 4% of the patients in the ICU had sufficient levels of Vitamin D.

-A study in the Philippines found that for every standard deviation increase in vitamin D people were 7.94 times more likely to have a mild rather than severe COVID-19 outcome and 19.61 times more likely to have a mild rather than critical outcome.

Those are dramatic differences. They are often phrased in a way as to prevent extraction of the most meaningful information, but the effect sizes are too big for that to be that big a deal here. If we combine these numbers with our ranges for the baseline rate of deficiency above, it seems like a really, really big deal.

The alternate explanation, other than outright fraud which seems in context rather unlikely, is that this is correlation rather than causation. Being sick or prone to get sick means you become deficient, being deficient doesn’t make you get sick. Or maybe both have a common cause. Vitamin D could be a proxy for ethnicity or age, or something else.

Pause for a minute. Assume that this is fully reverse causation or common cause. What would that mean?

It would mean that if you got tested for Vitamin D without changing how you supplement or how much sunlight you get, and you have sufficient levels, you are at very low risk! 

So what if it’s correlational? It still counts for your purposes. Take the New Orleans numbers. If about 50% of people in the USA have sufficient Vitamin-D levels, and only 4% of ICU patients (and presumably deaths from Covid-19 would be similar) do, then being in the 50% with sufficient levels should lower your risk by roughly 92% from baseline, through some combination of getting infected less often and being at lower risk once infected. Instead of something like a 0.3% risk of death, you’re looking at more like 0.03% risk of death. Combine that with being under 50 years old, and even if there’s some double-counting there to correct for, you gotta ask. Unless you’d put someone vulnerable at risk, why are you letting another day of your life go by not living it to its fullest? 

Maybe the other long term risks respond less dramatically. We don’t know, because somehow we have no data on them. Precautionary principle still somewhat applies. Sure. But look at what we’re giving up.

Now we have a full RCT (although not a blind one), and the effect size is gigantic. They treated hospital patients with or without calcifediol (effectively D3), and used ICU admission as the end point. There were 50 patients in the treatment group. None were admitted to the ICU. There were 26 patients in the control group. Half of them, 13 out of 26, were admitted to the ICU. So 13/26 vs. 0/50. Two of the control group died, none of the treatment group.

Do whatever complicated calculations you want. This wasn’t luck.

Possibility zero is that this was luck. This wasn’t luck. 

Possibility one is that this is real or mostly real. If that’s true, everyone supplements, patients get mega-dosed, and we can probably mostly resume our normal lives. This pandemic is no longer worth preventing.

Possibility two is that this is fraud. Always consider the possibility of fraud, especially when the effect size is this big. If anything, I’d like to think a fraud would choose results less dramatic than this, but the type of person who commits fraud doesn’t usually also carefully choose results to be believable or hard to disprove. Cheaters gonna cheat cheat cheat cheat cheat. 

Possibility three is doctor bias. This was suggested to me, since ICU admittance is a human judgment call. But look at the effect size. To get this effect size primarily from bias would mean that ICU admission criteria are meaningless and/or completely ignored. This is no less of an outright fraud, except lives are being risked and damaged for the fraud. I find this implausible.

Possibility four is publication bias or something, but that would require a ton of other studies we don’t know about that we’re rather confident didn’t happen, and also it would be luck. This wasn’t luck.

Possibility five is that this has some relation to them also giving everyone hydroxychloroquine and azithromycin. They did this to both control and treatment groups, considering it the ‘standard of care.’ There’s a large group convinced hydroxychloroquine has been proven useless and another large group that thinks it has been proven effective and is the standard of care, and I’m not going to get into that right now. It was suggested to me that it’s possible that Vitamin D only worked here because of the additional treatment, but the other observations suggest to me that this isn’t true.

I basically see this as a ‘either real or a fraud’ situation. I don’t know how to evaluate the chances of fraud.

This paper makes what I see as a convincing case that eliminating Vitamin D deficiency, at a minimum, should be a high priority. The paper thinks this is so well established for various reasons that further studies would not even be ethical. I think it’s almost never unethical to run tests to confirm your hypothesis when people weren’t otherwise going to get the treatment, because that’s ridiculous, but that’s “medical ethics” for you.

Our “medical ethics” is so screwed up that there is a very thin line between ‘allowed to do this study at all without being “unethical” to treatment group’ and ‘can no longer do the study without being “unethical” to control group despite them doing what they would have otherwise done anyway,’ so you need to grab your opportunities where you can get them.

Thus, hospitals are seen as being in active defiance of guidelines regarding plasma treatments, because they want to run experiments to find out if and how effectively it works, rather than turning on a dime from ‘this isn’t approved’ to ‘this is mandatory’ based on a highly politically motivated announcement.

I am supplementing 5000 IUs of Vitamin D daily. This is not medical advice because nothing I ever write has ever been or ever will be medical advice, “for legal reasons,” but I don’t see any substantial downside to that level. Again, it’s a freeroll. The more people that supplement, the better I’ll feel about it.

That’s the personal, practical side of this. 

On a broader level, replication is the name of the game. We should be doing more and bigger RCTs as soon as possible, and either confirm this is real (and figure out the real effect size) or find out it was a fraud. Test both the megadose for patients, and the regular dose for regular people, although that will take longer to sort out. 

The reasonable alternative would be to make the megadose the standard of care on the spot, given the effect size, decide that RCTs are no longer ethical, and see what happens. I think that’s a mistake, we need more data and it should only take a few weeks to get it, but I would understand it.

The unreasonable alternative is what we are doing. Which is nothing. But it makes sense that we’ve chosen that path. Of course we chose that path. 

I’ll conclude with some thoughts on that, but first, In Other News:

The Perfect as the Enemy of the Good

AstraZeneca Covid-19 vaccine study is put on hold because one person had an adverse reaction that might or might not be related to the vaccine. One. Out of thirty thousand. With neurological symptoms that seem on their face to be something entirely unrelated. Who is expected to recover. 

Now, somehow, the trial is on indefinite pause (it’s unclear what this means, but presumably no new participants and potentially no new doses either, so it could potentially invalidate the whole thing) and the entire vaccine is in jeopardy. 

Bloomberg’s news summary put it this way:

While AstraZeneca Chief Executive Officer Pascal Soriot told a private group of investors the precise diagnosis of the adverse event remains unclear, it could represent a serious setback for efforts to get a Covid-19 vaccine to the world quickly: If AstraZeneca’s review finds the adverse event is related to the shot, all the doses it has already manufactured will be thrown away, Collins said.

In other words, if one person has an adverse event linked to the vaccine, the vaccine is considered useless. All doses will be destroyed. 

If the vaccine ever does anything seriously bad, it’s no good. That’s it. Game over, man. Game over.

You. Fail. Statistics. Forever.

This is utterly insane. 

We could be more like Russia, which already is going ahead with its vaccine without waiting. Its results continue to look promising: Immunogenic in all 76 volunteers, with good neutralising antibody and cell-mediated response. No serious side effects recorded. 

Or meet somewhere in the middle. As Tyler Cowen points out, we could easily already have a vaccine ready at trivial additional cost.

Instead, well, whoops.

Football! Football! Football! Football! Football! Football! Football! Football! Football! Football!


We have football. Ergo, we might have peace.

The NFL returns this weekend. That’s excellent news. So too does much of college football. That’s also excellent news.

So too, in some stadiums, do a lot of the fans. That’s… not as excellent.

I’ve argued repeatedly that not only is football urgently needed, it is not substantially riskier for its players than it was in 2019 – worries about concussions and other injuries are a much bigger deal than Covid-19 risk, as the newly realistic discussions of the NFL make very clear. For college, being on the team is likely safer than the same kid would be as a regular student, as you get better testing and better protocols and less parties. 

None of that applies to fans attending games. Fans at football games are rowdy, completely out of control, yelling at the players and with each other not only because it is fun, but intentionally to create strategic noise. They’re drunk before they get to the stadium and then they keep drinking. The idea that such people could ‘socially distance’ or act ‘responsibly’ is obvious nonsense.

And yet we read about things like North Dakota State University allowing 10,000 fans into the stadium. Many other college stadiums are doing so as well. 

The problem with stupid people with bad motives doing the right thing for the wrong reason is that the next thing they do for the wrong reason is often going to be the wrong thing. 

Our problem of dumb people organizing themselves around being dumb is not football. It’s college.

School Hard With a Vengeance

That is not fair either to football or to college. 

I try to be fair to school. They don’t make it easy. 

This week, we have a student suspended for the display of a toy gun on his zoom video during a virtual class. Think about that. A toy gun, in a video shot, and he got suspended. 

No, wait. That’s the first version of the story I heard. Here’s the full one (WaPo). They sent the cops to his home. He now has a permanent record that he ‘brought a gun to school.’

We have regulations calling for punishment if children are not wearing shoes. For a zoom class. In their own house.

Colleges are charging students tens of thousands of dollars per semester, then kicking students out on the first offense for violating social distancing guidelines that actual everyone will violate from time to time, and keeping the north of $30,000 per semester tuition money. That they often have students take on non-dischargeable loans to pay. As one Twitter account put it, one dean who had just seen Charlie and the Chocolate Factory had an idea. 

Other schools are requiring students to be on campus and pay five figures for a tiny dorm room, because otherwise they won’t be able to do their single lab or other in-person required course, which would make them fail the whole semester. 

Many schools are taking away the scholarships of students who refuse to come on campus for safety reasons, and would prefer to wait things out remotely.  

Then these schools put out studies that call their students ‘an enigma’ because they only are willing to pay half of their outrageous tuition for virtual classes that don’t allow them to party and otherwise do what they came to college to do, but then when they do go to college, they do what they came to college to do, or in academic parlance, ‘engage in activities that present significant barriers to holding in-person classes.’ 

It’s a mystery!

We are home schooling our son. We are constantly pressured from all sides to torture him as if he were being tortured in a real school, because at some point in the future we will need to send him to a real school to be tortured, and if we don’t torture him exactly the same ways now, he won’t be prepared. 

Oh, and this one is my new personal favorite. Iowa Covid-19 rules say if you are close to a Covid-positive person for 15 minutes you need to quarantine… so an Iowa school is shuffling the kids’ seats every 12-14 minutes

We think this belongs in r/funny instead of r/childabuse:

If you’re wondering why we see headlines like Coronavirus: Teens’ anxiety levels dropped during pandemic, study finds, think about it and you’ll figure it out.

Every day it becomes more and more clear what school is for and what it is about. The answer is most definitely not learning reading, writing or arithmetic. 

Let that boy go outside. Maybe he’ll get to be a kid, and soak up some Vitamin D.

Imagine the Epilogue

An interesting exercise is to imagine that we find out that Vitamin D is the solution, it really does reduce risk from Covid-19 by 90%+, and by the end of the year life has mostly returned to normal, with some vulnerable people continuing to take precautions but everyone else accepting that life is never fully safe. 

What happens in that world? How do people react? What behaviors change? How do they judge? Who rises? Who falls?

Take a moment and model what you think happens.

My guess is that the primary reaction is righteous fury. 

We put our lives on hold for six months? And all we had to do was take a vitamin pill? That we mostly should have taken anyway? And all our best people, all our “health experts,” all the “science” we listen to, couldn’t figure that out?

Hell hath no fury. People would believe what they were told even less. Next time, they’d turn to a bunch of quacks hawking miracle cures, even more than they are already inclined to do that – and they’re pretty inclined to do that as it is.

In order words, everyone with authority and power pisses the public off and gets kicked in the nuts, and what little institutional credibility still exists is destroyed. Whoever gets to push the solution officially gets some of that back, but probably not too much. Yes, you found the solution eventually, but what about that whole time before? 

Good luck getting any kind of cooperation on anything, ever again, from pretty much anyone.

There would also of course be great relief, as we rapidly get to return things to normal. There would of course be a chorus of Very Serious People saying that even now we can’t return to normal, and we need to wait for a vaccine, and so on and so on. They might even be listened to and inflict massive damage, both general economic and reputational upon themselves. 

The whole thing would be looked back on as a farce, our civilization as pathetic. 

So maybe there’s upside to the whole thing. If we see ourselves as a pathetic farce that can’t do things, we can work on fixing that. It’s a lot better than what seem like the popular alternative positions: Either fooling ourselves into thinking that we’re great and can still do great things without having to fix things, or being fooled into thinking that we’re irredeemably evil and need to no longer have nice things because we don’t deserve them, and should promptly abandon all our core values and our prosperity. 

In any case, for now on the margin, it would be wrong not to consider this all very good news. We have a lot more of a locus of control over our lives and our fate than we did last week. Use it.

    Judging by how all brands of Vitamin D are in stock on Amazon right now, the news didn’t spread too far yet. I would be extremely surprised if the pandemic does end thanks to Vitamin D. Hopefully Russia or Iran or Japan or some other country that doesn’t care about Western ethics will stand up and do the right thing there.

  2. Dave Orr says:

    Vitamin D looks super promising. How do we gain enough confidence that it’s promising enough that we could just end lockdowns?

  3. yevterentiev says:

    >As Tyler Cowen points out, we could easily already have a vaccine ready at trivial additional cost.
    It was Alex Tabarrok.

  4. waltonmath says:

    You state that no one in the calcifediol group of the “Effect of Calcifediol…Study” was admitted to the ICU, but the study states that 1 of them was. However, that patient was discharged and survived, whereas two control patients died.

    Do you have any input on whether to get Vitamin D from ingestion or sun? I am looking at This article. It cites a paper which states:

    A minimum erythema dose (1 MED) amounts to about 30 minutes midsummer midday sun exposure in Oslo (=20 mJ/cm2). Such an exposure given to the whole skin surface is equivalent to taking between 10,000 and 20,000 IU vitamin D orally

    This sounds great, though it seems like one’d need more time to get those benefits as one dons more clothing or has darker skin, and I imagine overcast weather could make them impossible to get through standing outside. The first article mentions “winter”, but why wouldn’t wintertime sunning give the same benefit as summertime sunning, once you control for the weather?

    And I don’t know what the analysis looks like once you add in sunscreen.

  5. Jorge says:

    Considering the priors (renin-angiotensin hypothesis, overlap between at-risk population structure of COVID and Vit D def) and the fact that my reactive intuitive assessment of the calcifediol study was positive, I’m strongly recommending vitamin D to everyone in my family immediately. Like you say: it’s a freeroll.

    Is there a chance the study was fraud? Very small. I’d say less than 5%.

    Is there a chance some study-design bias warped the result? Small, but less so- call it 10%. Hopefully this gets replicated sooner rather than later.

  6. Echo Nolan says:

    The vitamin D experiment was actually open label, i.e. *not* double blind. See the “design” section of the abstract.

  7. Andrew Hunter says:

    I’ve been supplementing 5kIU/day of D since well, well before Covid. Recently I saw on HN which scared me a little bit. It pattern matches well to FUD but I’m not sure what the doctor in question *gets* from scaring me here.

    Certainly we’re failing miserably as a civilization that there’s any uncertainty about the right decision here but it does leave me frustrated. I wonder if you have thoughts?

    • TheZvi says:

      Yeah, I linked to her other post but not that one, which seemed like pure scaremongering as per normal in such situations. What does she get from FUD? She gets clicks! And she gets to look responsible and like a Very Serious Person.

      I’ve also been supplementing for years already and will continue for the rest of my life. It’s cheap, modestly likely to be beneficial and extremely unlikely to be detrimental. There’s plenty of large (100k+), sometimes decades long, studies that show a modest reduction in all-cause mortality correlated with vitamin D. I’ll take my chances it somehow negates some risk I would otherwise run.

      Same with magnesium, melatonin and glucosamine.

    Just got to the part about the vaccine.
    Are they *trying* to sabotage this?
    I feel like, at a certain point, you need to angrily “asking” “What the actual fuck?!” and *actually* ask, what the actual fuck. Because you don’t know.
    What the actual fuck, Zvi? Why is this happening?

    • TheZvi says:

      De facto, yes, they are. Is that their motivation? No, but they’re also basically don’t care when the vaccine arrives versus whether their “ethics” are followed. They don’t care about humans, and their values are opposed to life.

    More on schools being terrible: kid was suspended because of some Google searches for shit he thought was funny. Don’t we all want to know the funniest ways to die?

    One thing I failed to find out from the paper was how many of the 13 in the control group who were admitted had high blood pressure.

    Typo: (as waltonmath pointed out) one patient in the treatment group was ICU admitted, not zero.

    I’ve been taking a multi-vitamin with D in it for years now, regarding it as cheap dietary insurance. Sure, maybe I’m just paying to have more expensive piss, but maybe not. I also make a point of taking a walk in the sun at lunch time, if weather permits.

    A month ago I started D3 supplementation, just in case, but I’ll be scaling it back soon because it IS possible to OD if you keep high levels of supplementation up too long.

    “In order words, everyone with authority and power pisses the public off and gets kicked in the nuts, and what little institutional credibility still exists is destroyed.”

    The thing is, institutional credibility SHOULD suffer when institutions make egregious mistakes. And it’s sure looking like there has been no shortage of egregious mistakes this year.

  12. have you seen this:
    having been one of the first people in my surroundings to worry massively about covid and wanting the country shutdown (because, you know, herd immunity only at 70%, there’s going to be lots of dead people!!!), i’m pretty much in righteous fury mode as things are. vitamin D supplementation would be just the nail in the coffin.

      This is the first time I’ve come into contact with a seemingly rational COVID skeptic. +1 for Zvi to look at this video, direct link:

      At least he makes testable predictions: Cummins calls current spikes of COVID cases in the UK, the Netherlands and other countries “case-demics”, increased testing revealing more cases. AFAIK the tests are done for symptomatic people and their contacts, so I doubt his remarks about partial virus particles triggering the tests.

      However he has his point there, the daily case counts in the Netherlands are almost at their peak, but the death counts are at the noise floor. Alternative explanations off the top of my head include more experience, proportionally more hospital care, and the lockdowns actually working and protecting the most vulnerable population, while the second wave is caused by a younger people becoming more active and spreading the virus amongst themselves, but not dying from it. The patient age statistic would be handy to test the last theory, does anyone have this?

      His explanation of seasonality and different infection curves of the virus in different climates is also interesting, however this smells of cherrypicking, What about S. Korea, Vietnam or Australia?

      Brazil vs Peru comparison is also quite interesting… They have similar population densities (25 and 25.02 per km²) and urbanization levels (87% and 78% respectively), but Brazil shows better results desipte having “no lockdowns”. I haven’t followed the data from Soulth America closely, could someone propose a theory explaining this? Or this may be a cherry-picked comparison once again…

      The video includes too much of looking at similar graph shapes and too little of fitting predictive models, but this was the first piece of news to lower my concern regarding COVID.
