The problem is that these numbers are worthless unless they are expressed as percentage of total number of cases in that group. The numbers can only be taken directly if exactly 50% of the population is vaccinated and 50% not.
Think about it.
I agree that’s critical information, but this raw info is useful.
You could also back into it by using public vaccination rate information.
Eg — 70% vaccination and simply multiply.
Britain is around 80% vaxed which should mean that percentage is free from the Covid. Rather it shows there is little to no effect in stopping the virus.
