Description: | This historic 1965 photograph depicted a hand-held jet-injector, also known as a Ped-O-Jet, that was being used to introduce a vaccine into a recipient’s right forearm. The image was used to show how one properly places the jet-injector during vaccine administration. The original jet-injector was invented by Aaron Ismach in 1960, and was used throughout the World during the mass vaccination campaigns, which took place in order to eradicate smallpox. |
