Mode of Action
The VET JET™ transdermal vaccination system uses no needle. Powered by a 100-lb. internal spring, it delivers PUREVAX^® Recombinant Leukemia Vaccine through an orifice about the size of a 36-gauge needle into and through the skin for complete delivery of the vaccine in less than 0.3 second.

Vaccine is dispersed as it passes into and through the dermis, with some of the vaccine deposited into an area under the dermis abundant in immune-rich dendritic cells. These dendritic cells are the most effective of the antigen-presenting cells that initiate primary immune responses.

VET JET is a safe, consistent and convenient delivery system modeled after similar devices regularly used in human medicine. All components of the system are thoroughly tested for delivery volume specifications, pressure profile specifications, dosing accuracy and consistency. The VET JET dosing dial allows for measurement up to 0.5 mL, in 0.05 mL increments. Fail-safe components render a defective device unusable, preventing false injections.
