>What explanation is there other than the herd immunity thresholds being wrong? Just to give two possible alternative reasons: - outdoor life over the summer, leading to higher vitamin D levels; - older people are more likely to still be living in their summer cottages. Have you noticed that the death rate is possibly creeping upwards again? It’s simply too early to say. When I arrived back in Stockholm (from the countryside) three weeks ago, the town was very empty: our family was alone eating lunch in a central Italian restaurant on a Sunday. Now the streets are full again, but covid takes 3-4 weeks to take hold again. Not that I expect to see the levels of sickness from April again. But there’s a long winter still ahead of us.
