A precise understanding of the way in which an illness or disease spreads in society is often of decisive importance in the battle against it. Similarly, the necessity for and the rate of carrying our immunisations is strongly dependant on the way in which an illness spreads.
In the animation one can try out different scenarios. The simulated illness runs through the sequence shown in the bar (adjustable on the white spots) The simulation starts by pressing the "Start" button. By pressing the button "immunise", one can carry out a partial immunisation before or during the simulation. "Reset" takes the simulation back to the beginning.
