Study Data/Submissions

There are many big problems in Australia regarding vaccinations of our pets; one such problem is that the breeders and owners are not told about the proceedure of reporting adverse reactions to vaccinations and any related issues that arise shortly after vaccination. As a result, when you ask the treating vet about vaccine related problems the stock standard response is "There are no real problems related to vaccinations", or "There are very few incidences of vaccine problems"; anything along those lines tells you nothing at all because the reporting mechanisum just does not exist or at best is only limited.

Another is; that boarding kennels do not recognise immunity of your pet but rather want your pet to be subjected to annunal vaccinations in order for your pet to be kenneled.

This again brings me back to vested interests of the vet and the drug company that manufactures the vaccines; it is NOT in their best interest to tell you how to report such reactions in doing so you may decided not to punish your dogs or cats through unnecessary annaul vaccinations or those hideous multi in one combinations. All of which are "recommended" by the drug company that makes the product.

An open letter to Allen Bryce, Program Manager, Veterinary Medicines Australian Pesticides and Veterinary Medicines Authority (APVMA) by Elizabeth Hart©
The APVMA’s past failure to ensure that manufacturers’ MLV vaccine product revaccination recommendations are evidence based is at the heart of the continuing problem of unnecessary vaccination of pets, coupled with the reluctance of many members of the veterinary profession to keep abreast of and acknowledge the latest science on duration of immunity and vaccination ‘best practice’.


An open letter to Mark Lawrie, President of the Australian Veterinary Association and other representatives of the veterinary profession and government regulators by Elizabeth Hart©
Veterinarians in countries such as Australia, Britain and the United States continue to mislead pet owners with ill-founded vaccination advice, insisting they have their pets revaccinated 'annually' or 'triennially' with modified live virus (MLV) core vaccines for parvovirus, distemper virus and adenovirus when there is no evidence to support this ongoing practice.

I am astonished by your specious argument about annual revaccination of dogs in remote Aboriginal communities. As you admit, this is "not a situation that most Australian dogs or dog owners are familiar with".3 As the questionable sentence in the APVMA's Position Statement currently stands, I have no doubt that veterinarians will misconstrue this advice, and use it as an excuse to continue to unnecessarily revaccinate pets annually with MLV core vaccines in the general Australian dog population, particularly as it appears information on long duration of immunity with MLV core vaccines, and possible adverse reactions to vaccination, continues to be suppressed from the pet-owning public.


Unnecessary vaccination exposed by Elizabeth Hart©
The latest scientific evidence indicates that most dogs are likely to be protected from viral diseases such as parvovirus, distemper virus and adenovirus (hepatitis) after the final puppy core vaccination at 16 weeks. No further revaccination is likely to be required for these diseases, although pet owners can seek serological testing if they wish to verify their dog’s antibody status.


Consumer Voice Paper by Elizabeth Hart©
I wish to raise concern about the lack of consumer protection for consumers of veterinary services in Australia. According to statistics, 12 million Australians are associated with pets, 63% of the 7.5 million households in Australia owns pets3 so this issue is relevant to many Australians.


Over-vaccination of pets – an unethical practice by Elizabeth Hart©
Many veterinarians are ignoring international dog and cat vaccination guidelines, and continuing to send reminder letters compelling pet owners to have their pets unnecessarily revaccinated for diseases such as parvovirus, distemper virus and adenovirus.1 This unethical practice of over-vaccination is of no benefit to the animal and puts it at needless risk of a range of adverse reactions, including death.


Over-vaccination:Are vets making our pets sick? by Elizabeth Hart©
The author’s interest in this subject was initiated after her own dog, Sasha, an eight year old Maltese x Silky terrier, became mysteriously ill with haemorrhagic gastroenteritis (i.e. “bloody diarrhea”) a week after her last booster revaccination, and was subsequently put to sleep. The veterinarian was unable to provide an explanation for Sasha’s illness, but refused to consider it could have been a delayed adverse reaction to revaccination.


Fibrosarcomas at Presumed Sites of Injection in Dogs
Characteristics and Comparison with Non-vaccination Site Fibrosarcomas and Feline Post-vaccinal Fibrosarcomas
by Vascellari M.[1]; Melchiotti E.[1]; Bozza M.A.[1]; Mutinelli F.[2]

Fifteen fibrosarcomas, surgically excised from presumed sites of injection in dogs, and 10 canine fibrosarcomas excised from sites not used for injection were histologically and immunohistochemically compared with 20 feline post-vaccinal fibrosarcomas. Canine fibrosarcomas from presumed injection sites were of grade I (3), of grade II (4) and grade III (8). Two fibrosarcomas from non-injection sites were of grade I, four of grade II and four of grade III. Feline samples were classified as grade I (2), grade II (4) and grade III (14). All fibrosarcomas from presumed injection sites of both species showed lymphocytic inflammatory infiltration located at the tumour periphery, while two canine fibrosarcomas from non-injection sites showed perivascular inflammatory infiltration within the neoplasm.


Adverse Vaccine Reactions by Dr W. Jean Dodds
Viral disease and recent vaccination with single or combination modified live-virus (MLV) vaccines, especially those containing distemper virus, adenovirus 1 or 2, and parvovirus are increasingly recognized contributors to immune-mediated blood disease, bone marrow failure, and organ dysfunction. 1-11 Potent adjuvanted killed vaccines like those for rabies virus also can trigger immediate and delayed (vaccinosis) adverse vaccine reactions.7-10 Genetic predisposition to these disorders in humans has been linked to the leucocyte antigen D-related gene locus of the major histocompatibility complex, and is likely to have parallel associations in domestic animals. 5, 7
