Over-vaccinating is relative. Effective or not, does anyone really know the impact of vaccines? If the vaccine isn't necessary, then it is over-vaccinating. Our last dog had the rabies vacc annually per the law. It didn't hurt her that we know of, but she was being over-vaccinated. |
Vaccines against bacterial disease are not as effective as vaccines against viruses. Lepto, Lymes, the 'Dental' vaccine are all bacterial in nature and the diseases/illnesses can be treated successfully with antibiotics.
The problems with overvaccination first became evident in cats, as cancer began developing at the injection site. When I was at the vets last time for vaccines, there was a little dog figure drawn in their charts and the point of vaccination was clearly marked on the diagram, so that future vaccines will be given in a different spot. They are also giving more vaccines in the leg, because if cancer does develop, the leg can be easily amputated, thereby stopping the progression of the cancer.
