In order to reproduce the COVID-19 spread with accuracy it is necessary to model the simulated environment in a realistic manner. EpiGraph includes five different models that are executed in coordination: the epidemic model that provides the COVID-19 propagation behaviour, the social model that depicts the characteristics and relationships of individuals within the population, the transportation model that considers the movement of the individuals, the environmental model that represents the ambiental elements (weather, pollution, etc.) that modulate the spread of the infection. We have recently incorporated a
vaccination model, that captures the characteristics of each COVID-19 vaccine.
