Simulation for different immunity scenarios

As vaccinations roll out, we work towards herd immunity, there are various challenges to consider along the way. Thomas Wilburn and Richard Harris, reporting for NPR, used simulations to imagine three scenarios: a more infectious variant of the coronavirus, high initial immunity, and low initial immunity. Since it’s a simulation it of course doesn’t consider every real-life detail of immunity and viral spread, but the animations and the hexagon grids...

Visual explanation for how herd immunity works

Herd immunity works when you have enough people who are immune to a disease, maybe because they already got it or there’s a vaccine, so that the disease can’t spread anymore to those who don’t have a resistance. For The Washington Post, Harry Stevens is back with simulitis to demonstrate how this works in greater detail. It starts at the individual level, generalizes to a larger group, and then zooms...
