The irony of this, of course, is that this was the position of Jenny Harries (and of everyone who genuinely 'followed the science')
before the mask mandate, when she was merely Deputy CMO.
The
political (for that's what it was) decision to mandate masks required her 180° turn, for which she was handsomely rewarded with promotion to Head of the new NSA.
Now safe, she can stop simulating and revert to 'the science'.
They certainly did a job on people (not me, happily).
