Again, remember that social distancing was to "flatten the curve". It was not automatically assuming better final statistics. It was to decrease the strain on the healthcare system at one time. Hoping that, eventually, it would improve outcomes for individual patients. Which is likely, but not guaranteed yet.
"Sweden’s idea of herd immunity didn’t work. End of story.I agree that it is a little suspicious, but it is not end of the story yet. Not in Sweden, not in Brazil, not in the U.S.A. Sweden merely chose not to "flatten the curve", but to, sort of, take a hit at once. It is a different approach with its own shortcomings, but it is hard to assume that long-term outcome will be much different.
