I think it’s best addressed by noting this in the future when it comes up—can’t be going back and editing weekly news posts. I’d be more worried if I didn’t still firmly believe the same conclusion anyway.
Another interesting piece of evidence is a study on homeless people in Boston (who would likely not be vitamin D deficient because more outdoor time):
“100% of 147 COVID-19 positive subjects were asymptomatic.”
Source, which doesn’t really make the connection: Baggett, T. P., Keyes, H., Sporn, N. & Gaeta, J. M. COVID-19 outbreak at a large homeless shelter in Boston: Implications for universal testing. medRxiv 2020.04.12.20059618 (2020) doi:10.1101/2020.04.12.20059618.
A more-studied effect on Vitamin D is that of skin color. This is especially seductive since it’s well-established e.g. Black Americans suffer Covid disproportionately, and also are deficient in Vitamin D disproportionately. But the effect seems to disappear after adjusting for confounders:
The skin color study confirms that vitamin D doesn’t protect against infection. But I don’t see it saying anything clear about how much harm a person suffers if they’re infected.

That’s intriguing. Another news article on Covid/Homeless, I’d love to see more evidence: https://www.latimes.com/california/story/2020-08-21/why-has-covid-spared-l-a-homeless-people
