Caricature of Edward Jenner inoculating patients in the Smallpox and Inoculation Hospital at St. Pancras. The patients are shown growing cow heads from parts of their anatomy following the vaccination. There is a print of the golden calf on the wall behind them.
Patients are spoon-fed "opening mixture" as they come through the door. A boy standing next to Jenner is holding his pot labelled "vaccine pock hot from ye cow", on his jacket is a badge saying "Pancras" and in his pocket a paper entitled "Benefits of the vaccine process".
