Introducing the Pebble Game; a simple app for exploring epidemics and vaccination

The Pebble Game is a shiny application that simulates a simple game which has been designed to reflect real world epidemics and the vaccination programmes used to control them. It involves repeatedly drawing pebbles from a bag, which contains two distinct pebble types (to represent vaccinated and unvaccinated individuals). The number of pebbles that are drawn each round is dependent on the number of infect-able (i.e unvaccinated) cases drawn in the previous round, and the infectiousness of the simulated disease.
