The Guardian has a great animation that demonstrates how measles can spread through communities with different immunization rates. The animation accompanies an article published in 2015, titled “Watch how the measles outbreak spreads when kids get vaccinated — and when they don’t,” during the outbreak associated with Disneyland at the time. Although it’s not a new resource, or article, the animation is timely and offers another tool for explaining the phenomenon of herd immunity.
