Visualizing & formulas behind herd immunity

[Akimbo]

I normally would not post a "non-diving" thread here but Covid19 is impacting divers, the diving industry, and ScubaBoard so adversely. I found this video that does a good job at helping people visualize herd immunity AND explains how it is calculated.

​

I hope you find it as interesting as I did.

Thanks Akimbo. I found it interesting. Especially the mouse trap demonstration which showed how the infection rate of the virus developed exponentially without a vaccination. I appreciated the formula.

There is also a similar video that demonstrates the effect that Social Distancing has using mousetraps & ping pong balls.
