Frequently Asked Questions
Here are answers to your questions about the VET JET™ transdermal vaccination system.

Q: How does the VET JET transdermal vaccination system deliver the vaccine?

A:	The transdermal injector is loaded with a 100-lb. internal spring which, when released, forces the vaccine through a tiny orifice (with a diameter similar to that of a 36-gauge needle) into the animal’s skin and underlying tissue — in less than 0.3 second.

Q: Can I use a needle and syringe to administer PUREVAX^® Recombinant Leukemia Vaccine?

A:	No. PUREVAX Recombinant Leukemia Vaccine was developed exclusively for use with the VET JET transdermal vaccination system. It was administered only using the transdermal injector during product testing and so is licensed for use only with the VET JET transdermal vaccination system.

Q: Can I use the transdermal injector with other vaccines or injectables?

A:	Because of its distinct antigen concentration, only the PUREVAX Recombinant Leukemia Vaccine can be used with the VET JET transdermal vaccination system at this time.

Q: How can I be sure the vaccine has been delivered?

A:	The VET JET transdermal vaccination system is made using components that render defective devices unusable, thus preventing false injections.

Q: What are the immunological benefits of transdermal vaccination?

A:	Because it creates a wide dispersion pattern that deposits antigens directly into the immune cell-rich layers of tissue, transdermal vaccination induces a rapid, targeted presentation of the protective antigens with a low vaccine volume.

Q: How can PUREVAX Recombinant Leukemia Vaccine offer the same protection with a much smaller dose?

A:	Because of the direct, efficient presentation of the antigen to immune cells, PUREVAX Recombinant Leukemia Vaccine — when administered transdermally — can afford the same protection as larger doses delivered with a syringe.

Q. How can I learn more about PUREVAX Recombinant Leukemia Vaccine and the VET JET transdermal vaccination system?

A:	By contacting your Merial sales representative, or calling 1-888-MERIAL-1 (1-888-637-4251).
