A few years ago I learned that vaccinating my pets every 1-3 years was unnecessary. In fact, it is down right harmful. With the exception of the Rabies vaccine, I have stopped giving my pets booster shots.
I hope the reprint of this article will help you make an informed decision for your animal companions.

RE: LD 429, An Act to Require Veterinarians to Provide Vaccine Disclosure Forms
My name is Kris Christine and I live with my family in Maine. Before I begin my testimony, I’d like to advise the committee that one of the world’s leading veterinary research scientists, Dr. W. Jean Dodds, wanted to be here today to testify in support of LD429, but could not do so because of prior commitments. With her permission, in the attachments to my testimony, I have included her letter to Representative Peter Rines dated February 17, 2005 (Attachment 5) resolutely endorsing this first-in-the-nation veterinary vaccine disclosure legislation.
I am here today to respectfully urge this committee to recommend passage of LD429 – An Act to Require Veterinarians to Provide Vaccine Disclosure Forms because pet owners need the scientifically proven durations of immunity (how long vaccines are effective for) in order to make informed medical choices for their animals.
Many Maine veterinarians have failed to inform clients that most core veterinary vaccines protect for seven or more years, and pet owners, unaware that their animals don’t need booster vaccinations more often, have unwittingly given their companions useless booster shots – taking an unnecessary toll on their finances and animals’ health. The human equivalent would be physicians vaccinating patients against tetanus once every year, two years, or three years and not disclosing that the vaccines are known to be protective for 10 years.
For years veterinarians have sent pet owners annual, biennial and triennial reminders for redundant booster shots and justified it with vaccine manufacturers’ labeled recommendations. According to the American Veterinary Medical Association’s (AVMA) Principles of Vaccination (Attachment 6), “..revaccination frequency recommendations found on many vaccine labels is based on historical precedent, not on scientific data … [and] does not resolve the question about average or maximum duration of immunity [Page 2] and..may fail to adequately inform practitioners about optimal use of the product…[Page 4] .” As the Colorado State University Veterinary Teaching Hospital states it: “…booster vaccine recommendations for vaccines other than rabies virus have been determined arbitrarily by manufacturers.”
Dr. Ronald Schultz, Chairman of Pathobiological Sciences at the University of Wisconsin School of Veterinary Medicine, is at the forefront of vaccine research and is one of the world’s leading authorities on veterinary vaccines. His challenge study results form the scientific base of the American Animal Hospital Association’s (AAHA) 2003 Canine Vaccine Guidelines, Recommendations, and Supporting Literature (Attachment 7). These studies are based on science – they are not arbitrary. The public, however, cannot access this data. The American Animal Hospital Association only makes this report available to veterinarians, not private citizens, and Maine’s pet owners are unaware that the AAHA Guidelines state on Page 18 that: “We now know that booster injections are of no value in dogs already immune, and immunity from distemper infection and vaccination lasts for a minimum of 7 years based on challenge studies and up to 15 years (a lifetime) based on antibody titer.” They further state that hepatitis and parvovirus vaccines have been proven to protect for a minimum of 7 years by challenge and up to 9 and 10 years based on antibody count. So, unless the Legislature passes LD429 requiring veterinarians to provide vaccine disclosure forms, dog owners who receive an annual, biennial, or triennial reminders for booster shots will not know that nationally-accepted scientific studies have demonstrated that animals are protected a minimum of 7 years after vaccination with the distemper, parvovirus, and adenovirus-2 vaccines (see Page 12 AAHA 2003 Guidelines attached, and Table 1, Pages 3 and 4).
“My own pets are vaccinated once or twice as pups and kittens, then never again except for rabies,” Wall Street Journal reporter Rhonda L. Rundle quoted Dr. Ronald Schultz in a July 31, 2002 article entitled Annual Pet Vaccinations may be Unnecessary, Fatal (Attachment 2). Dr. Schultz knows something the pet-owning public doesn’t – he knows there’s no benefit in overvaccinating animals because immunity is not enhanced, but the risk of harmful adverse reactions is increased. He also knows that most core veterinary vaccines are protective for at least seven years, if not for the lifetime of the animal.
The first entry under Appendix 2 of the AAHA Guidelines (Attachment 7) “Important Vaccination ‘Do’s and Don’ts” is “Do Not Vaccinate Needlessly – Don’t revaccinate more often than is needed and only with the vaccines that prevent diseases for which that animal is at risk.” They also caution veterinarians: “Do Not Assume that Vaccines Cannot Harm a Patient – Vaccines are potent medically active agents and have the very real potential of producing adverse events.” Very few pet owners have had this disclosed to them.
The AVMA’s Principles of Vaccination (Attachment 6) states that “Unnecessary stimulation of the immune system does not result in enhanced disease resistance, and may increase the risk of adverse post-vaccination events.” (page 2) They elaborate by reporting that: “Possible adverse events include failure to immunize, anaphylaxis, immunosuppression, autoimmune disorders, transient infections, and/or long-term infected carrier states. In addition, a causal association in cats between injection sites and the subsequent development of a malignant tumor is the subject of ongoing research.”(Page 2)
Referring to adverse reactions from vaccines, the Wall Street Journal article cited above (Attachment 2) reports: “In cats there has been a large increase in hyperthyroidism and cancerous tumors between the shoulder blades where vaccines typically are injected.” With modified live virus vaccines (distemper, parvovirus, hepatitis), some animals can actually contract the same disease which they are being inoculated against. If the public knew an animal’s immunity to disease is not increased by overvaccination, they would certainly not consent to expose their pets to potential harm by giving them excessive booster shots.
Veterinary vaccines are potent biologic drugs – most having proven durations of immunity much longer than the annual, biennial or triennial booster frequencies recommended by vaccine manufacturers and veterinarians. They also carry the very real risk of serious adverse side affects and should not be administered more often than necessary to maintain immunity.
The extended durations of immunity for vaccines is not “new” or “recent” science as some members of the Maine Veterinary Medical Association (MVMA) have claimed. AAHA reveals on Page 2 of their Guidelines that ideal reduced vaccination protocols were recommended by vaccinology experts beginning in 1978. A Veterinary Practice News article entitled “Managing Vaccine Changes” (Attachment 3) by veterinarian Dennis M. McCurnin, reports that: “Change has been discussed for the past 15 years and now has started to move across the country.”
According to a September 1, 2004 article in the DVM veterinary news magazine (Attachment 1), the 312 member Maine Veterinary Medical Association (MVMA) “champions full disclosure of vaccine information to pet owners.” MVMA president, Dr. Bill Bryant, is quoted as stating: “Its time for something like this to come out … disclosure forms will be an important resource to have available, [and] if it goes before the Legislature, we’d likely support it.”
It is time. Pet owners have the right to know the scientifically proven durations of immunity for the veterinary vaccines given their animals, as well as the potential adverse side effects. LD 429 would make that standardized information available to all pet owners.
