The figure shows Gillray’s colour cartoon depicting a scene in a vaccine institution. The patients are crowding in through a doorway on the left. In the foreground on the left is a medicine chest on which there are some bottles and a syringe, and a large tub of some medicinal mixture. The doctor’s assistant ladles this into the mouths of the patients. There is a large and frightened-looking woman seated in an armchair in the centre. The doctor (Edward Jenner) holds her right arm and cuts it with his knife, while a deformed and ragged boy holds up a bucket of the cowpock vaccine. On the right of the picture is a pregnant woman, who has a cow coming out of her mouth and another emerging from under her petticoat. Just behind her is a man dressed as a butcher with horns sprouting from his head. In the foreground on the right there is a labourer leaning against a pitchfork; a cow is bursting from a swelling on his arm while and another one breaks through the seat of his breeches.
