Yes there is a correlation between Vitamin D deficiency and COVID mortality. But you are not just saying that. You are saying that the effect size coming from Vitamin D explains a significant portion of the excess mortality in Sweden. That's just a guess and it's weird that you would make that conjecture when there's the wildly spectacular policy difference between Sweden and everyone else. Neither of the studies you linked support that. I don't have time to read the studies you linked. If you did, what is the relative impact of socioeconomic status, the fact that the most polluted zip codes in NYC are predominantly black neighborhoods, and vitamin D deficiency?
