I asked NPHET to come back with a formal view on it for exactly the reasons laid out by the Deputy. NPHET has published a paper on it, which I will ask the Department to send on to the committee.

My non-medical synopsis of the paper is that it was very positive about vitamin D generally in boosting the immune system. I may be wrong on this, but, from memory, I believe its conclusion was that there was not evidence specifically linking it to a higher resistance to Covid-19. I will ask for the paper to be sent to committee members, however.
