Not sure why you are talking about modelling - the impacts of vaccination will hopefully kick in at 75-80% first dose, but then when you let the say 10% unvaccinated (some may cancel their second dose, some may not take up their first dose appointment) out in a post 80% double dose world, some will get sick/covid and need hospitalisation etc....so "commonsense" would say its likely to go up but hopefully be nowhere near breaking the health system - isn't that the point of the 80% rule in the first place?!?!
