I think the term 'community immunity' sound much better than 'herd immunity'

[Siwsan]

Dr. Jerome Adams on CNN just used the term on CNN. Perhaps it's weird, but that's the first time I've ever heard it.

1. Mooooooo!!!

Yup I agree.

2. Herd Immunity is a very old term and yes, it does have origins in livestock disease control

but it has been used in human public health/epidemiology at least dating back to the 1700s, if not earlier--smallpox, typhoid, and other contexts.

Populations = Cohorts = Communities = Herds

3. Cities are a lot like feedlots

4. Alliteration is always good.

Now, a poster:

commUNITY
immUNITY

With the "unity" part bolded, expanded, and shared between the two words.

And underneath, "Get Vaccinated!"

There y'go. Short, pithy, and it fits on a bumper sticker.

5. Precisely!

Being Welsh, anything that even hints at poetry speaks to my soul.
