What advances have been made with DSJI technology to prevent cross-contamination?
DSJIs improve the safety of immunizations and the safety of those administering them in developing countries. New jet injectors solve the problems of previous generations of devices which had the potential for cross-contamination of the nozzle orifice. On these redesigned devices, new, sterile, single-dose, needle-free syringes are used for each injection; the syringe is discarded after a single use, preventing cross-contamination between patients. The simple design allows for safe administration by many levels of health care professionals; in addition, no change in vaccine formulation is required.
