Sweden appears to have hit herd immunity in about 6 months. While we argue back and forth about insane lockdowns. The lockdowns should be for the old, sick and obese, the people who are mostly at risk.
There is no evidence of that. Serology testing has generally shown between 2-10% of various populations have had it, and in a few cities as much as 20%, but those are the exception. Even at 20%, that would still be at least half the standard typically required for herd immunity.
As for Sweden itself, it seems only the government is saying their strategy worked (because of course they would), but doctors and scientists who know this stuff suggest immunity even in Stockholm was no more than 10% at the end of July. https://www.politico.com/news/2020/0...mmunity-381117
Given that Sweden has one of the world's highest per-capita Covid death rates, and if immunity even in its largest city is still that low, it'd be a complete failure.
Thailand has 3,000 cases. How could they have herd immunity? 70 million live there.
There are cases of people being reinfected and the antibodies leave the body rather quickly. We are at 5 million cases, even if its really 50 million we are only at 15%. At this rate we are years away from herd immunity assuming that is even a real thing.
They also have a pretty authoritarian government, so it's more likely to be Iran than Taiwan in terms of honest reporting of numbers.
The fact is that every single nation has more cases and deaths than officially reported. Because that literally happens in every pandemic. The true cost is never known until after, either because governments hide the numbers or because there is too much going on to gauge the accuracy of the data.
This is somewhat in question. There are a few ways the body creates immunity from what I understand- antibody and T-cell responses. Antibodies always decay eventually, but at different rates depending on different viruses. T-cells, however, can remember how to produce new antibodies should the body become exposed again. The virus has only been around like 8 months, and comprehensive studies on immune responses have been too few and with too small group samples to know exactly how long the antibodies last and whether T-cells end up providing a more lasting immunity.
There's also the question about re-infection or a second surge of symptoms. This is anecdotal, but a friend's family caught the virus in May, tested positive, had only very mild symptoms, recovered, tested negative and last month suddenly felt much more sick and tested positive again. There is some question whether it's a re-infection or the virus hiding dormant inside the body and somehow reactivating to produce a worse illness. There have been similar reports of this all over the world.
I agree we do not know exactly how this virus plays out in the body long term.

I guess you have to look at overall deaths during the pandemic and compare to before and after. Because Trumpers keep saying that they are calling all sorts of other deaths covid deaths. The overall deaths will tell the truth.
