Agreed...but I think you will also agree that the vast majority in ICU are 60+ hence cannot have received any other vaccine but AZ so virtually all in ICU have either had no vaccine or AZ.
So your statement "a quarter who are in ICU had the AZ jab" is kind of misleading as it makes out AZ is far less effective than Pfizer.
This may turn out to be the case but you can't draw that conclusion on that statement..
