This workshop aimed to bring together people working on modelling the COVID-19 pandemic in the UK to discuss how modelling has and continues to inform policy decision making. It showcased ongoing modelling efforts to evaluate different non-pharmaceutical interventions as well as potential vaccination strategies from the leading modelling groups in the UK, drawing on knowledge from published and in the process of publication work. We also had discussions and brain-storming sessions about the ongoing modelling efforts surrounding COVID-19.
