I strongly believe we haven't so much got a viral epidemic, we've primarily got a vitamin D epidemic, and the virus is exploiting the "cracks" in the health of the population. Something like 96% of critical and severe cases of covid are either vitamin D deficient or insufficient. See attached graph. We need to get blood levels up to over 75 nmol/l (ideal range is 100 - 150).
On that basis I would fortify foodstuffs with vitamin D (bread and milk). Report in today's Observer:

I would give everyone going for a flu vaccination an additional shot of vitamin D while in the surgery. Report in Australian medical journal here:

Ideally I'd give out vit D3 tablets to the whole population. The raw materials cost £5 per person for a 25 year supply (obviously manufacture and distribution would bump it up a bit... but still). Tiny, tiny, trivial amounts compared to the humungous costs of lockdown, healthcare costs, costs of government borrowing that will take decades to pay back, impact on the wider economy, not to mention the human suffering and bereavement impacts. It would also massively reduce other diseases associated with low vitamin D levels, such as T2 diabetes, hypertension, some cancers, some forms of depression. Many of these are co-morbidities associated with covid. Surprisingly sensible voice for Tory quarters here:

Study from Córdoba hospital with patients admitted with covid:
50 went into the treatment group (best available treatment PLUS the acitve/fast acting form of vitamin D). Of those only one (2%) was admitted to ICU, none died, all went home without complications.
26 went into the control group (best available treatment, but no vitamin D). Half of them required admission to ICU and two died. See graph 2
Although this was a smallish study, it was a randomised double blind control study, the gold standard in medical research.
