@metal-brain saidI do not know the exact, just the basic idea. Vitamin D is part of the puzzle.
What about now? The equinox has passed and we have more than 12 hours of light per day now. You need to establish a correlation of UVB and Vitamin D in the spring. You have not done that.
It has been demonstrated that Vitamin D has a significant effect on respiratory virus infections.
By the way an earlier story I gave already explained UV b and spring. The University of Oregon link.

A simple test is to look at your shadow. If its the same height or shorter than you, you’re getting enough sun to make vitamin D. If its longer than you, you’re probably not. In most places in the US in the winter, you can probably guess what you’re going to see.

@eladar saidThat really doesn't tell me much. I live at the 45th parallel. If I go outside on a warm sunny day to do yard work in a T-shirt for a couple of hours am I getting enough UVB for vitamin D conversion?

The equinox was nearly 3 weeks ago. I should be getting about the same UVB now as I would in early September. The earth is a little closer to the sun this time of year than fall, but it shouldn't make much difference.
I don't doubt vitamin D deficiency is a factor, but I am not convinced it is the main factor. People still get influenza in April. I have noticed I tend to get a runny nose when it is cold and I don't have to be sick for it to happen. Maybe it is something as simple as that.
@Metal-Brain
You should measure your shadow. If it is shorter than you are then you are making vitamin d.
How much of your skin is exposed? How light is your skin color? Are you wearing sun block?
By the way, I believe it is just one factor. Your body takes time to build up vitamin d levels.

@eladar saidLook, you're overstating the importance of this. The relative risk of not getting ill when taking vitamin D compared with placebo is 1.4 according to the Finnish study I cited on page 2 of this thread. This is a small effect.

If vitamin D was all it took to protect from the virus there wouldn't be a pandemic, it'd just be a matter of getting people to take some vitamins.
@deepthought saidWere they supplementing with 10k to 30k levels of vitamin d?

No only 400
They were not giving neatly enough vitamin d.
@eladar saidI'm not going to measure my shadow. That is stupid and unscientific with no regard for accuracy.

I'm pretty sure I can get enough UVB light this time of year doing yard work. Your theory has holes in it.
@metal-brain saidIt has to do with the elevation of the sun in the sky. If the elevation is above 45 degrees then you are getting UVB.

At this time of year if you are outside at noon, then you will be getting UVB. How much skin exposed, your skin color and if you are wearing sun block cream all plays a part.
But if you are pretty sure, I suppose that makes you right.
@Metal-Brain
You do understand it takes time for nutrients/hormones to build up in your body. After a winter of depleting your vitamin d, it will take weeks, perhaps months to get your vitamin d levels back to optimal levels.

What is your source of information?
