Instead of using a needle, Injex 30 propels a fine stream of insulin through a tiny opening in the end of a disposable ampule. This pressure, they say, “pushes the insulin through the skin and into the subcutaneous tissue.”
The Injex 30 sytem has been used in a clinical trial to deliver the measles, mumps and rubella vaccine to test subjects. It was found to be as effective as a needle delivered vaccination in raising antibody levels. As they put it, “The results demonstrate equivalent immunogenicity in the study of adolescent subjects. Based on these results the Injex injector is a safe and effective alternative to standard needle syringes in the vaccination of subjects in the MMR vaccine for immunity to measles, mumps and rubella.”
This quote comes from a study the company sent me. If you are having trouble convincing your child’s doctor, it would be worth calling or writing the company to get them to send you this study. It is called, “Clinical immunogenicity of measles, mumps, and rubella vaccine delivered by the Injex jet injector: comparison with standard syringe injection.” It is reprinted from The Pediatric Infectious Disease Journal, Volume 19, No. 9 September 2000. It is copyrighted of course or I would have the whole thing here.
They point out that Injex also eliminates the risk of accidental needle sticks and the hassle (and danger) of needle disposal.
