"a brief overview of the most catastrophic flaws in its design:

The doctors gave patients a single dose, one that barely qualifies as a high dose despite the study description, that earlier research on Vitamin D, conducted four years ago, proved doesn’t work. In other words, they designed a study that was entirely unnecessary because the outcome was known beforehand. The research was a complete waste of everybody’s time and a betrayal of the patients who took part because nothing could be learnt from it.

Even worse, the form of Vitamin D the researchers gave the patients needs 10 days to become available in their bodies, far too late to help these seriously ill patients in their battle against Covid. Another form, calcifediol, which is available for use by the immune system immediately, should have been given instead, as it was in the Spanish study.

In addition, not only was the wrong form of Vitamin D given but it was administered to patients 11 days after the onset of their symptoms – a huge time lag that, as Dr Vasquez observes, would ensure that many established drug treatments – for illnesses such as influenza, for example – would be guaranteed to fail too.

The combined delay in treatment and the delay in the Vitamin D becoming active meant the patients had to wait three weeks before their Covid was being treated in any meaningful way. But that was the point at which the study ended and an assessment was drawn about Vitamin D as an ineffective treatment."
