— The U.S. Food and Drug Administration (FDA) is warning veterinarians about a possible risk of fractures associated with a device used to deliver the feline leukemia vaccine through the skin of cats.
The Vet Jet transdermal vaccination device, made by Bioject, is sold exclusively as the delivery system for Merial’s PUREVAX Recombinant Feline Leukemia Vaccine, according to FDA.
FDA says it has been notified of three adverse events using the Vet Jet in kittens. In two of the cases, the user may not have properly locked the nozzle into the device before using it, says FDA. The nozzle dislodged at the time of vaccination and caused a fracture of the femur.
Merial is investigating all three cases, according to FDA, and revising its instructions to stress that the nozzle must be securely locked into place. A letter will be sent by Merial to all users.
FDA is asking veterinarians to report any problems associated with the device to Merial, or to FDA by submitting form FDA 1932a. (Click here
