I did wonder why Vallance used the example of a Sixty year old man.
As far as I know the percentage of the total number in the raw data has suggested 0.012 for all mortality sub 80 yr old, so if it was so would be 0.015 to that age group and below.
You may get an increase just from the fact the system has become overwhelmed I guess,but to reiterate the data from hospital's hasn't suggested this .
But even that needs to be interpreted as treatment has improved between first wave and this.
If you it ends up only 30% effective it's going to fool many people into dropping their guard.
It's going to take month's to determine the efficacy and that will have to be outside of lockdown.
