I'm worried that Vitamin D is the new facemasks.
We have all of this suggestive evidence that Vit D might have a big impact on COVID19. An ordinary person hears this and thinks —

...if Vit D might help reduce the severity of COVID by any material amount, shouldn't we push hard to get everyone taking it?
Or give everyone a big dose when hospitalised?
The pandemic is so devastating even a small reduction is worth billions."
And yet despite that... 2/

As a result it ends up having to jump an unreasonably high evidential bar.
