It is simple arithmetic but the anti-vaxxers are trying to bamboozle people. Here's a simplified example which might help. The numbers are hypothetical.:
If 50 people are vaxxed and 50 people are unvaxxed and the vaccination has no effect on hospitalisation rates then you would expect the numbers in hospital to be 50/50 respectively.
If 80 people are vaxxed and 20 people are unvaxxed and the vaccine has no effect you would expect the numbers in hospital to be 80/20 respectively.
If 80 people are vaxxed and 20 people are unvaxxed and the numbers are 68/32 then there are 12 fewer vaxxed people in hospital than there would be if the vaccine had no effect.
