I checked all my resources today and could not even find a rumor of injection site carcinomas related to a 3yr Rabies vx in canines. The major manufacturers of the vaccines offer the same vaccine with a 1yr label and 3yr label. The vaccine itself is the same.
Most hospitals pull the label off the vial and put it into the chart, some must like having label match the validation of the certificate. Like Deanna we use Imrab 3 for all, but do offer the PureVax Feline adjuvent free vaccine. The core vaccines like DHPP can also given with a 3yr protocol after the initial series.
Lepto is not common in our area, but I wish more would do the Lyme vaccine, we have had a bad tick season. Bordetella is another good vaccine to have on board.
Molleigh was given the "Dental Vaccine" by NGAP. I will be interested to follow her mouth to see if it does help.
