It is difficult to equate any other country to Sweden. Swedish people are mostly hard working Lutherans who are very fit. They ride around Stockholm, for example, on clunker bikes with no gears.
They are acclimated to their climate so that they get a lot of vitamin D from the sun.
Here in the US we have many races. With the not so bright sun all of us need extra Vitamin D but we have many races who require a lot of Vitamin D because they are acclimated to places with more sun. Often they are not those educated to the fact that the need the D that they do not get from the sun with extra pigment in their skin.
By the same token, but off subject, those who believe that here in the US we can have a nice little socialism in the US that they have in Sweden, we cannot. We do not have a majority of hard working Lutherans but instead we have a lot folks that want free stuff for nothing.
So we cannot equate the health and economics in this country to that in Sweden. Not everyone here is blonde, hard working and fit.
Not at Sweden's latitude, they don't.
Vitamin D deficiency is a common condition of so many that had trouble with covid. The simplest and cheapest thing anyone can do for their health is get some sunlight. Even on a dim winter day it is helpful. Sunlight light triggers D production. Even just your face and eyes being exposed helps.
This advise is rarely dished out by the medical industrial complex because it cuts into their profits. During lock down many people were fooled into staying in their house. They should have been in their back yard or on their porch getting some sun every day.
