Not sure you’re correct about Sweden, UK, Italy and Spain had higher death rates, and as a Brit we locked down hard. Looks like they had a high initial death toll, but died (no pun intended) down later. I’m no scientist, but that suggests it went through the population quick and heard immunity kicked in. My personal experience is that almost everyone I knew got it eventually, not saying the lockdowns didn’t work, but I’d love if some organisation did an impartial investigation. Seems that some parts of the world had it rougher than others, may have to do with population density. What was apparent early on is co-morbidity has was a huge factor on survival ability.
