Very interesting model, thanks for writing this up!
I will have to think about it in more depth. How do settings fit into this scenario where we know that basically everyone (50-75%) gets infected in an arguably short time frame: meat plants, close living quarters or prisons?
I agree that this is a relative weakness of the model. I think part of it is that the division into vulnerable/invulnerable is a simplification. If for instance you injected somebody with COVID then everybody would be “vulnerable”. So in some environments conditions are ideal for spread which makes many relatively immune people become infected.
