I don't think herd immunity is "applied", it is simply the end result if containment measures aren't enough to stop the virus on their own, then it keeps going until it eventually turns the other way because enough people ended up getting infected to do that. That's what has happened in places like New York and Boston where cases continued to rise long after lockdowns were implemented, but did not go on rising forever and eventually turned the corner once enough of the population had gotten it. I don't think herd immunity was intended, or some sort of strategy, it's just an explanation for why we see the patterns in those places that we did. It is on the other hand wrong to attribute their current success as compared to places that have not yet faced as large a wave to their supposedly superior policies, when they have a big advantage if you just look at current case counts from the fact that a lot more of their people have already had it.
Sorry in a hurry.
1. Sweden "applied" herd immunity. UK originally tried and said nah...

Yes New York and Boston didn't want herd immunity and they didn't get it. Less than 60% of the population has the virus.
3. I don't understand your logic. They got hit hard and they recovered that's a success. a) their cases could continue to rise and it would be like 1918. They avoided that so that's a success. b) You have countries like Taiwan, Hong Kong, etc that avoided the death so that's great. You also have countries like Canada, Germany that were hit hard initially but managed it successfully that is also good. Not great but good. That strongly suggests their actual superior policies were superior because of less cases, hospitilisations and deaths. To simplify - Arizona, Florida, Oklahoma, Texas, Georgia were all avoidable.
1.Sweden actually does not describe their approach as targeting herd immunity. If they were presumably they wouldn't have any restrictions, which they in fact do. The point their leaders made, which is clearly true, is that whatever measures you put in place to limit spread will have to be substainable, becuase if they are the reason for reduced spread, but are not sustainable then you'll just get that spread whenever you inevitably have to lift those measures. Now of course you can disagree with the measures they took, and believe that there are certain additional restrictions they should have put in that you think would have been effective and sustainable, but that's not "targeting herd immunity". A strategy of actually targeting herd immunity would be an attempt to get young people or others believed to be low risk infected, and no one has actually done that. In fact everyone has engaged in some level of restrictions, the question is just which ones were effective and sustainable.
2. I already addressed this, so you should go back and read that post, but the 60% threshold is based on a simplified model that does not capture the observed reality that a small percentage of people cause the majority of infections. This fact has major implications for the herd immunity threshold, and could bring it down in to the 10%-20% range. This is in fact what epidemiological models say the impact of such heterogeneity is.
3. The question is what the success is attributed to. If the change occurred way after lockdowns were at their maximum intensity, then it can not reasonably be attributed to the lockdowns alone. There must also be another factor. And the added factor, having a significant proportion of the population already having had it, persists now, which is why it's not right to compare states currently to each other without acknowledging that those who have already been through one large wave and sufferred a lot are at an advantage if you're looking at current spread numbers. Is the current uptick in California avoidable? Why not included on your list? I think they've been at least as cautious as Massachusetts has, but they largely avoided the earlier wave, so now have a more susceptible population which makes even a similar or in fact more restrictive reopening than Massachusetts harder for them, just because less of their population has had it yet.
I'm sorry I just don't understand your points.
1. in the article they say herd immunity. But I don't want to inject my opinion, I have attached a research paper. I'm not interested in semantics, it's herd immunity. There are other research papers I can attach if you like so I don't understand how you can say it's not herd immunity when that is exactly what it is.
https://www.orfonline.org/research/swedens-soft-covid19-strategy-an-appraisal-69291/2. You didn't address it well is the issue, is my problem. Herd immunity is a theory where the percentage is a projection. Correct. haha but you can't arbitrarily just change it without a mathematical basis to do so. It's not the first time that observations don't match theory and if you want to change it to prove your point then I do not. I want to stick to the recognized percentage associated with this model, simplified or not.
For example - this example from the Mayo clinic says 70% is needed for the US.
https://www.mayoclinic.org/diseases-conditions/coronavirus/in-depth/herd-immunity-and-coronavirus/art-20486808Another report for 70%
https://www.sciencealert.com/why-herd-immunity-will-not-save-us-from-the-covid-19-pandemichttps://hub.jhu.edu/2020/04/30/herd-immunity-covid-19-coronavirus/Anyways that's like the least important part of my point. My point was Boston and NY, even with all their cases, never hit the percentage needed for herd immunity. Which means that they can still get a lot more people sick if they didn't do the policies they did. You focused on the percentage for some reason and you were still wrong.
3. Success is less people died that could've and that has a direct correlation with policy. I don't understand why you can't see that. I was going to link research papers but it's that simple. You're playing with words to try and make a point that is not there to be made. What nonsense are stating about unknown factors. We're not looking for dark matter here, there is no mystery. Of course California is avoidable. No, I wasn't going to list every single state. California WERE cautious. They stopped and then there was a rise. That's why I ask Hank - hey what's going on in California because he lives there. I believe what he's saying because it makes sense and I find it reliable. And Mass. is doing well because less people died. I am sorry you wanted more to die to go back to your herd immunity. However this isn't a video game. Keep numbers low until we have a vaccine / cure.
Talk to Fairview about this, I truly don't understand your points. I'm so sorry I don't, it's me really. He will probably understand it better but I have a feeling he also values life.
