This was one of the likely explanations for why the homeless weren't dying of COVID, despite obviously unsanitary conditions and unhealthy lifestyles.

They spend so much time outside that they naturally have good vitamin D levels.

From the perspective of your immune system's cells, what exactly does the vitamin D molecule do?

Probably nothing. High vitamin D levels are a side effect of being outdoors a lot and therefore getting more exercise than the deskbound population. I recall during lockdown listening to a Slate Star Codex article (on the Astral Codex Ten podcast) which went through a stack of papers and concluded that there was nothing to see here.

The article should be retitled "Pre-Infection exercise levels associated with severity of Covid-19 illness".

Correction: the Astral Codex article gives a 25% chance that vitamin D might do you good.

is it even possible to be vitamin deficient with western diet?

With Vitamin D specifically I think the answer is yes.

It's not like this was discussed 2 years ago on "conspiracy" channels or anything.... /s

I stil remember the "horse dewormer" propaganda about ivermectin.

some people never really believed that ivermectin was a horse wormer after reading that its been in use as an antiviral agent for ages, but can you explain what you mean by propaganda to someone who does not follow mainstream news networks (e.g. fox, MSNBC, CNN, etc.) and instead prefers independent media (i.e podcasts, disclose.tv, project veritas, etc)?

If you search on "horse dewormer", you should be able to find lots of mainstream articles ridiculing it, and also Joe Rogan was made fun of a lot for using it instead of vaccines.

If you can't find it on Google, maybe you need to use Duckduckgo or even better, sign up for Kagi search beta. :)

Yet the answer was to force people indoors where their vitamin d levels go down.
