NB The Fiddaman model is highly simplified. He explains this in the video. The big issue is no connection from recovered back to susceptible.I also wonder about the bigger system impacts...on health (esp mental health), the economy and so on. And of course, there are no vaccines modelled here.

ISee systems have created a simulation model of Covid [https://exchange.iseesystems.com/models/player/isee/covid-19-model here]. It has more explicit structure (eg on testing) but does not feedback recovered into uninfected. And no vaccinations...

It will be interesting and informative to build a simple SD model of the vaccination program especially given the differences in efficacy of 1 or 2 doses of different vaccines. Article title "When will it be safe to go out again?"

She uses a free simulation modelling facility called AnyLogic (see [https://cloud.anylogic.com/models here]. It enables agent based modelling as well as discrete event and continuous (SD) simulation.
