Dr. Ronan Glynn:

Ventilation will certainly be a key component of the messaging through the autumn and winter. On vitamin D, leaving aside Covid and the different views in regard to Covid and vitamin D, what I can say for certain is that a significant proportion of our adult population in this country are vitamin D deficient. Even if Covid had never come along, we should be encouraging people to get adequate levels of vitamin D, particularly as we move into autumn and winter. That should be a component of our public health messaging more generally, and regardless of Covid, over the coming months.
