Re: Covid-19 Polticians taking charge of an "orphan drug"

Dear Editor

It is disgraceful to refer to a hormone with a 500 million year evolutionary history as an "orphan drug".

"Vitamin" D3 supplementation is now being advised by a cross-party group of parliamentarians in Eire, following discussions with D3 experts.

It appears that politicisation is necessary to inform the public of the most important contribution to health, inlcuding covid-19, that they lack. Unfortunately the Eire politicians need to revise dosage upwards, towards 4000 IU pd, the dose taken by most of the 200+ signatories belonging to the international group the author referred to as the "Vitamin D for All Coalition". D3 has had 500 million years to refine our defences against microbes, vaccines a mere 400 days for C-19. We need both, so a big cheer for the politicians in Dublin.
