Can I ask about PPE? Will you publish formal medical advice from the chief medical officer on the use of protection, facial protection, by the public? And did you act on the recommendations of the New and Emerging Respiratory Virus Threats Advisory Group, the Scientific Advisory Group for Emergencies sub-committee, when it proposed that face visors and eye goggles were added to the pandemic stockpile in 2016, and when it did similarly as regards surgical gowns in June of last year?
