I'm sure I'm just misunderstanding, but I don't follow the explanation. What do UVA and UVB have to do with this, and why does that lead to weird results?

The reason covid is dangerous is because it binds overly tightly to your ACE2 receptors on the cells in your endothelium and damages them, and when enough of these receptors are damaged the cells die. This can cause all sorts of issues like autoimmune cascades, blood clots, dysregulation of blood pressure and heart rate, etc. The reason vitamin D is protective is because when you're exposed to UVA, the vitamin D acts as an enzyme that your body uses to produce nitric oxide in your skin and capillaries. Nitric oxide is directly antiviral, but even more importantly it upregulates your ACE2 receptors. With more ACE2 receptors there is less damage caused when some of them are destroyed, which means you are less at risk for blood clots, problems with your heart and blood pressure, deadly autoimmune cascades, etc. Basically being exposed to UVB causes your body to produce vitamin D, but once you have the vitamin D you need exposure to UVA for your body to produce nitric oxide, which is what causes the health benefits. The reason smoking is beneficial for covid btw is because nicotine also upregulates the density of your ACE2 receptors. And the reason women are less likely to die is also, you guessed it, because they have more ACE2 receptors. Aside from vitamin D, you can also obviously upregulate your ACE2 receptors by taking any other food that causes your body to produce more nitric oxide, and/or by taking any ACE inhibitor. OTC things in this category include garlic and hawthorne, and most of the other foods that are commonly used to lower blood pressure.

  Do you know if you can get this beneficial UVA from an artificial lamp? Is it as good as going outside? Is it good enough to be a near-replacement or is it even worthwhile as a supplement?

    > Do you know if you can get this beneficial UVA from an artificial lamp? I mean artificial tanning uses UVA lamps. But since you can get UVA even in winter, it's probably safer and more effective just to go outside.
