It's not "nonsense". It's real. It works for almost every other virus out there (even colds and flu, even though it's imperfect: new seasonal cold and flu strains don't become pandemics, because many people have some immunity from previous infections). If you let a large enough fraction of the UK contract and recover from COVID-19, we have every reason to suspect that the society will develop good enough herd immunit…

3. the immunity gained through an infection holds for a long enough time (how long would need to be checked with the infection rate), which we do not know yet Additionally, we know nothing of the long term effects even for the "young and healthy". Mortality rates for people 10-39 is 0.2%, 40-49 it's at 0.4%, 50-59 1.3%, 60-69 at 3.6%. Serious conditions develop in a bigger proportion of cases, so you are looking at 4…

Yes, the idea that only those 70+ are "at risk" is weird. But they probably can't afford to isolate everyone 50+ - both from an economic and herd immunity viewpoint - so they will risk losing 3.6% of people aged 60-69 and 1.3% of people aged 50-59.

According to https://www.statista.com/statistics/281174/uk-population-by-...

8.96 million aged 50-59, 7.07 million aged 60-69.

I'm going to go with the guy who was awarded an OBE for his work in infectious disease control: https://www.lshtm.ac.uk/newsevents/news/2016/leading_infecti...

OBE is a political honour, not a scientific one.

Definitely insane, here's why:

In order to get to herd immunity, you need something around 60% of the population to get infected and thus immunized [0] (there's a big assumption here already, that immunity lasts forever, might well be wrong). The UK's population is 66 million people, so that's about 40 million who need to get sick.

Let's assume 2% of cases require intensive care (it's closer to 10% in Italy right now [1], but we can assume for the sake of this calculation that the UK has the superpower to isolate people over 65 or so perfectly). That's 800000 people who will require intensive care!

There are about 4000 ICU beds in the UK [2]. Let's assume, again highly optimistally, that only 50% are occupied, so 2000 are available for Covid19-patients. Covid19 patients may need to spend 7 days in the ICU [1], which means there can be up to 286 new Covid19 patients starting intensive care each day.

You can see where this is going. At that rate, it would take 2797 days to reach herd immunity. It's utterly nonsensical. We will hopefully have a vaccine way, way before that. What this "herd immunity" strategy is actually going to do is lead to a total break-down of the hospital system in the UK, if the government doesn't change course real soon now.

[0] This is 1-(1/R_0), see https://en.wikipedia.org/wiki/Herd_immunity and unmitigated R_0 is around 3 for SARS-CoV-2, https://en.wikipedia.org/wiki/Severe_acute_respiratory_syndr...

It’s already too late. They’re on the Italy path. This “herd immunity” thing is nonsense. So much so that doctors and scientists are warning against it: https://www.theguardian.com/world/2020/mar/14/coronavirus-nh...

Some are against it, others (such as presumably a majority of those advising the government) are for it. That's just good debate. > It’s already too late. They’re on the Italy path. Well, that's pretty much the point of the policy. 'Already screwed this year, let's try to cope, and be less screwed next year'. I was very critical at first, but I'm more interested/satisfied with the response now, it does seem to be wel…

One point neglected in discussions is the effect of spreading it to other territories that are not adopting a similar strategy. The majority of cases in the English-speaking Caribbean to date have been from persons who traveled to the UK recently.

> No no, I understand that. But the thinking is, and it seems to be backed by data, that the health system will be able to cope with a full-population maximal pandemic, as long as it is limited to the much less vulnerable segments of the population. It really doesn't seem that you're getting it, because the whole point of this exercise is that it's quite patently obvious that no health care service in the world is ab…

> the expected incidence of cases that require medical care. Among the general population! Among people under 50, the best data we have is that the fraction needing ICU care is something like 0.2% (I think, I'd have to look it up again). The intent is to quarantine the at-risk and let it propagate in the "safe". I genuinely think it's you who's failed to understand the plan. You're arguing against something that is n…

Do we actually have evidence that this quarantining is possible or working?

This ignores the risk of spreading the virus to other populations.

Because the models the government's epidemiologists are using explicitly don't account for all possible actions. Back when this was taking off in China, a bunch of epidemiologists came out and said it was completely uncontrollable there. They were wrong, because they hadn't accounted for the extreme actions the Chinese government was willing to take; it was not even a possibility in the models. The same story repeate…

These may be legitimate criticisms of the UK government's epidemiologists - I'm not in a position to judge - but I'm not sure it explains why we should be listening to Tomas Pueyo on the matter.

Well, you don't have to. There are plenty of actual epidemiologists unhappy with the government's actions. Just because Pueyo was arbitrarily chosen to represent one side doesn't mean professional support for that side doesn't exist.

Honestly, choosing a bad representative for a position is a classic media tactic for unfairly discrediting that position.

Herd immunity by mass exposure is an interesting, very likely catastrophic, approach. It's interesting that he (of the twitter cite) claims that it is "more refined", as if simply doing nothing and rationalizing your hubris is 4D chess.

Every country realizes it can't be stopped now. Every country realizes that the majority of the population will get it. But as has been cited a thousand times, having hundreds of thousands of vulnerable people, along with a substantial enough number of otherwise healthy people, needing heroic medical care would be disastrous. See: Italy. Their approach wasn't "more refined".

I doubt the outcome is going to be good.

"I was very critical at first, but I'm more interested/satisfied with the response now"

It sounds more like you're at the bargaining stage now, rationalizing why it might be a good approach because it's happening and you hope for the best.

It sounds insane. Italy quite literally did the same model. Now they're in the worst of both -- mass quarantine / enormous economic damage AND the brutal human toll.

I haven't checked too closely, but surely the age distribution of conservative voters is such that if they are so callous as to treat corona as a convenient boomer remover, they torpedo their own re-election chances. So, _even if_ you ascribe to the current UK government a conspiracy-esque, cold as nails approach to just effectively _murder whole boatloads of older folks_, it doesn't actually make sense: Who would th…

Replace “boomer remover” with “working-class-boomer remover” and the strategy makes more sense. Personally, I don’t think Johnson and his cronies are deliberately targeting this or that group. They just don’t care . They are scared like everyone else, and are prioritizing the survival of their immediate circles and their social status - i.e. they keep the economy working, keep an appearance of order, and ensure peopl…

> Saving a bunch of working-class grandpas

The problem is there is currently no known way to save them.
