One shot, closest wins nothing....
What year did Edward Jenner introduce the world's first successful vaccine?

I know it was the smallpox vaccine.
No idea on the year. I could be a century off or more. I'll try 1907.

I think Jenner goes back farther than that, 18th-19th century. I'll go with 1801.
