Jenner vs Snow: should a plague be prevented or traced?

← All debates · Talk to Caleb

EDWARD JENNER vs JOHN SNOW go head to head — and every jab is rooted in real history.

EDWARD JENNER

I taught the body to fight the disease before it ever arrives - a scratch of cowpox, and smallpox loses its throne forever.

JOHN SNOW

Noble, Edward, but I removed one pump handle on Broad Street and watched the cholera die in the streets - you inoculate the body, I heal the city.

EDWARD JENNER

You map where the sickness has been; I ensure it has nowhere left to go. Prevention outlives every investigation.

JOHN SNOW

And prevention is blind without knowing WHY the sick fall sick - I gave you the map, John; your needle is useless if you're aiming in the dark.
