Jet Infectors

Needleless Vaccination Devices, known as Jet Injectors, once administered inoculations to children, civilians and military personnel. These devices were abandoned due to their capability of transferring blood-borne pathogens such as Hepatitis B, Hepatitis C and HIV.

Jet infectors?! In reading a transcript to a FDA Panel Discussion on jet injectors, I was surprised by an error. Being late at night, I readjusted my eyes to see if I was mistaken by what I saw. On the contents page, the stenographer titled the discussion— “Guidance Development for Jet Infectors” (FDA, 1999). The stenographer, intending to write Jet Injector, had mistakenly, yet simply and accurately captured the reality of these devices. Jet Infectors have the potential to infect subsequent vaccinees. The symbolism is perfect.”

Jet Infectors refer to the first generation jet injection devices known as multi-use nozzle jet injectors (MUNJI) and second generation devices known as protector-cap needle free injectors (PCNFI). Third generation jet injectors, known as disposable cartridge jet injectors (DCJI), use a disposable cartridge that is discarded after a single use, thus eliminating the risk of cross contamination to subsequent vaccinees. Disposable cartridge jet injectors have become the standard in needle-free jet injection technology.

Military veterans from the Vietnam era and Post-Vietnam era were repeatedly exposed to jet injections. An influx of Hep C / jet gun claims within the Department of Veterans Affairs upholds this exposure as being one of the possible causes to the high prevalence of Hepatitis C amongst these cohorts.
