Mass Jet Gun Immunizations


Jet Injectors were used in mass immunization programs across the United States and around the world for over five decades! Multi-Use Nozzle Jet Injectors and Protector Cap Needle-free Injectors, pictured below, should not be used due to the risk of transferring blood and disease. Newer model devices, known as Disposable-Cartridge Jet Injectors, eliminate the risks posed by previous generation jet injectors.





Jet Infectors aims to:
• Bring awareness to the risks and hazards of jet injectors.
• Ban the use of Multi-Use Nozzle Jet Injectors and Protector Cap Needle-free Injectors.
• Identify other incidences where mass jet injector vaccination campaigns transmitted pathogens.
