My ex-colleague Lawrence did a simplified simulation on how vaccination can work to slow down the spread of Covid-19. It shows a clear correlation between rate of transmission and percentage vaccinated. Of course, experts recommend 80% vaccination rate but every bit counts as you can see from the simulation. I will be sure to receive mine when we get our turn.
It could also be useful for educating the public on the continued need for social distancing/masks despite having a sizeable population being vaccinated.(Note: p = probability of spread upon contact, and you can use the dropdown menu to select different modes of safe management measures)
