When people post "suspicions" you let them go without comment but when I post an actual official document you try and make out I was hiding something even though it is there for all to see and read ? my mind boggles.
There's only 1 footnote, not a and b - the comment a refers to b as a fuller explanation.
if there was a hospital with 100 beds, and only 35 people in the world are left unvaccinated and they were all admitted, the other 65 beds were occupied by vaccinated people, then even though there are billions who are vaccinated, the hospital still only has 35% non vaccinated.
If the same hospital was in a universe where 400000000 million billion zillion people were not vaccinated and 65 people were, and 35 non vaccinated people were admitted and the 65 people vaccinated were admitted it still only has 35% unvaccinated people.
As you are implying there's something wrong with my original comment, I've quoted it above for you - please explain exactly what is wrong with it
The footnote to which you refer is shown for several tables, including some which have no admission / occupancy data - it's a generic comment and not relevant to table 9.
