PATH: Jet injector: fast facts

Disposable-syringe jet injector (DSJI) technology has the potential to provide safe and affordable vaccine delivery to millions of people around the world.
DSJIs may improve injection safety in developing countries by eliminating reuse of potentially contaminated needles and syringes, preventing needlestick injuries, and reducing the overall burden of sharps waste.
DSJIs are needle free. They use a sterile, single-dose syringe and a pressurized liquid stream rather than a needle to administer vaccines and medications.
DSJI is the only available needle-free technology that can deliver all injectable vaccines used in developing-country programs, at all depths of delivery—intradermal, subcutaneous, and intramuscular.
No change is required in vaccine formulation for use with a DSJI.
A DSJI syringe is discarded after each single-dose use, preventing cross-contamination.
Simple design allows for safe administration by many levels of health care professionals.
Design advancements of DSJIs accommodate future trends including single-dose packaging or prefilled syringes.
The product design of DSJIs may allow less vaccine to be wasted per injection.
There is potential for DSJIs to deliver reduced doses of vaccine intradermally for some vaccines—up to 80% less. Research indicates that intradermal delivery of certain vaccines could reduce the cost of each vaccination and thus increase their availability when they are in short supply. DSJIs could provide a reliable means of administering these vaccines intradermally—potentially enabling a substantial cost-savings for immunization programs and improved vaccination coverage.
At full production scale, DSJIs may be comparable in cost to administering immunizations with needles and syringes when one compares all the costs associated with injections, rather than just the devices themselves. Cost savings come from DSJIs’ advantages in reducing sharps waste, preventing needlestick injury, and reducing vaccine wastage.
