Interesting paper (full version here) indicating strong relationship between severe Vitamin D deficiency country-level CV19 mortality rates in Europe. Severe Vitamin D deficiency is defined as seroprevalence < 25 nmol/L. The researchers use 2019 Vitamin D European population data reported in a recent European medical journal.

These are high correlation coefficients and, as suggested by Graph 2, the relationship is strengthening with time.

Lends additional credence to the role of seasonality and geographic region in explaining viral effects.


btw, here is a fine video that reviews the science on Vitamin D and viral interactions.
