Yes it's a great step through analysis. I was going to try and replicate it, but it was easier to just post the link.
Anywhere that 'raw' hospitalised numbers look the same for vaccinated v unvaccinated, you can apply the same process.
People should be really careful about taking shallow analysis using 'raw' or 'gross' numbers at face value. The people pushing those types of figures either don't quite understand what they are talking about, or are doing it on purpose which is far worse.
