Size, 25.5 mm.
 
Edward Jenner inoculated a young man on May 14, 1796 with a vaccine made of the pus of a coxpox sufferer in order to test his theory that it would protect against the ravages of smallpox.
The reverse has to do with the introduction of inoculations in Berlin by a Doctor Bremer in 1811. "Dr. Bremer alone at the Royal Institute in Berlin inoculated 14,605."
Struck from silver on a relatively thin planchet. I'm not certain why there is a indentation in the obverse exergue but it appears deliberate.
* "8 Lot and 6 Grän (approx. 0.523 fineness, Prussian weight units for the silver content: 1 Prussian Lot = 16 Grän, so 134 Grän in total of 256 maximum possible Grän)"
