I thank Deputy Leddin. Before I call Dr. Nabarro, I want to revert to the panel with the questions from Deputies Stanton and Leddin. I refer to Dr. McMahon's response to the points raised by Deputy Stanton. Could I put it to her that the herd immunity through vaccination that we thought was possible late last year and early this year is now unlikely to be possible because of the emergence of further and new variants such as, for example, the strains in South Africa and, we suspect, South America? Does she agree that we are seeing a movable feast or shift in the projected goalposts, which adds to the challenge involved?
