> Early COVID-19 research found that most patients with optimum levels of vitamin D did not require ICU or breathing assistance and survived the infection.

Some sources point out that only 10-20% cases of covid are admitted to intensive care unit, and 80-90% of cases are mild.

I seriously doubt that up to 90% of the population has "optimum levels of vitamin D".

There have been at least 100 million confirmed cases of Covid in the US. Do you believe 20 million people stayed in the ICU with Covid?

You can’t reverse an implication like that. “Most patients with X did not require Y” is not the same thing as “most patients who did not require Y had X”.
