For all the graphs, I have the national range in the background in grey: the bottom is the lowest per capita rate by any health region and the top is the highest per capita rate.
Quick thread on vaccines, outbreaks, and why *who* is vaccinated as much as how many (although both are very important)
There's a pre-print out that gives estimates (based on sero-prevalence) of the probability of needing to go to the hospital or dying if infected with SARS-CoV-2 for a series of age brackets: medrxiv.org/content/10.110…
If you know a population's age structure, you can somewhat estimate what an outbreak of a given number of infections will look like in terms of number of hospitalizations and deaths.
And if you know vaccine coverage, you can update those estimates for those effects, too.
