I thank all the witnesses for an extremely informative discussion. Even though I was always aware that vitamin D was good I did not realise how important it is. I think it was Dr. Daniel McCartney who spoke about the importance of getting out the message, particularly in this very difficult time, about the importance of vitamin D. We need to focus on getting out that message.

It is essential that we introduce a fortification and supplementation policy urgently to combat the deficiency in the hopes of saving people from experiencing more severe Covid-19 symptoms. Last November, we were aware that the UK introduced free vitamin D supplements to those who were at risk of Covid. People could apply to the NHS for free daily supplementation. We might need to look at introducing a similar model, particularly for those who are at risk and also for members of society who are more likely to suffer from vitamin D deficiency such as the elderly and people with more melanated skin.

I am aware of the growing evidence and reports that study the correlation between iron and the efficacy of the vaccine. One very interesting study came out this week from Professor Luke O'Neill at Trinity College Dublin. He spoke about iron and the immune system and I want to ask about that. We know iron is a mineral that we need for all things in our bodies but our immune system needs iron also. The very compelling evidence shows that iron deficiency makes vaccines less effective. Should we be planning to supplement iron as well as vitamin D in the fight against Covid?
