The Science Has Been Done


References are provided to support the following

1. Duration of Immunity studies on large numbers of animals  have been done.

2. Endogenous antibody interference with vaccines, blocks re-administered vaccines from enhancing immunity.

3. Dogs over 8 weeks of age do not develop any disease from canine corona virus

4. Dogs are at low risk of developing Leptospirosis in Texas.

5. We do not have Lyme disease in Texas.

6. Vaccines can cause Injection Site Fibrosarcomas, or Vaccine Associated Sarcomas VAS. Non- Adjuvanted Vaccines are safer than adjuvanted vaccines, in that they are less likely to cause VAS.

7. Titers do not accurately predict which dogs will respond to another vaccination.

8. It is misrepresentation, a deceptive trade practice, for a Veterinarian to recommend, charge for, or administer a vaccine, where there is no scientifically proven benefit to the patient, or that a reasonable client would not elect to purchase or have administered if given the information necessary to make an informed decision .

1. The duration of immunity for Rabies vaccine, Canine distemper vaccine, Canine Parvovirus vaccine, Feline Panleukopenia vaccine, Feline Rhinotracheitis, feline Calicivirus, have all been demonstrated to be a minimum of 7 years by serology for rabies and challenge studies for all others.

Minimum Duration of Immunity for Canine Vaccines:

Distemper-        7 years by challenge/15 years by serology

Parvovirus –      7 years by challenge/ 7 years by serology

Adenovirus –    7 years by challenge/ 9 years by serology

Canine rabies – 3 years by challenge/ 7 years by serology
