Over-vaccination of pets - an unethical practice

Many dog owners are still not being advised that there is no scientific evidence to support annual OR triennial revaccination with core modified live virus (MLV) vaccines for parvovirus, distemper virus and adenovirus.

The World Small Animal Veterinary Association’s (WSAVA) Guidelines for the Vaccination of Dogs and Cats note that duration of immunity after core MLV vaccination is “many years and may be up to the lifetime of the pet”.[1]   It is misleading for veterinarians to demand that already immune pets have bogus ‘booster’ shots every year or every three years.  (Core MLV vaccines for dogs can be compared to the live Measles/Mumps/Rubella (MMR) jab for children – adults are not revaccinated with the MMR jab every year or every three years as these vaccines are likely to provide lifetime immunity.)  

Many pet owners remain unaware of the option to have titre-testing to verify their pet has responded to core MLV vaccination.  Non-core vaccines of questionable benefit and safety for diseases such as Bordetella bronchiseptica (often referred to as ‘kennel cough’) continue to be prescribed indiscriminately.

In Australia, pet owners Bea Mies and Elizabeth Hart have been campaigning for ethical and evidence-based vaccination of companion animals.  As a result of their persistence, change is slowly happening in companion animal vaccination practice.

It is a disgrace that members of the public have to be the leaders for change due to the failure of self-interested experts/professionals in the veterinary vaccine industry.

Elizabeth Hart’s essay “Over-vaccination of pets – an unethical practice” provides some background on this subject.  The Australian Veterinary Association (AVA) announced a new reduced vaccination policy[2] soon after Elizabeth’s essay was widely circulated in June 2009.  (After demands from dissenting AVA members, the AVA’s vaccination policy was subsequently downgraded to a position statement in July 2011).[3]

In January 2010, the government regulator of veterinary vaccines, the Australian Pesticides and Veterinary Medicines Authority (APVMA), issued a position statement on Vaccination Protocols for Dogs and Cats, acknowledging matters of concern in regard to re-vaccination intervals.  State veterinary boards in Australia subsequently blatantly disregarded the APVMA’s request for the APVMA’s Position Statement to be circulated to veterinarians in Australia.

In August 2010, CHOICE, Australia’s consumer watchdog, published its report on over-vaccination of pets i.e.

“Pet vaccination: Over-vaccinating your pet could be harmful to their health as well as your own hip pocket”.  The ABC also reported on this story i.e. Questions raised over pet vaccination, broadcast in October 2010.

In May 2011, specialist dog breeder magazine, National Dog, published Elizabeth’s article  “Vaccination failure!” which warns there is a potential for maternally derived antibodies (MDA) to interfere with a puppy’s response to core vaccination, and calls upon the World Small Animal Veterinary Association’s (WSAVA) Vaccination Guidelines Group to provide clear and objective advice on optimal puppy vaccination, and an optional titre test confirmation protocol.

In February 2012, Bea Mies addressed the industry sponsored WSAVA Guidelines for the Owners and Breeders of Dogs and Cats, arguing that advice to pet owners contradicts scientific findings published elsewhere.

Bea’s latest email to Professor Michael Day, Chairperson of the WSAVA Vaccination Guidelines Group, and Sarah Mitchell of Pfizer Animal Health, provides critical analysis of their Canvac vaccine study paper, recently published in the December 2012 edition of the Australian Veterinary Journal[4].  Bea argues their paper is the latest instalment of willfully misleading and ethically dubious veterinary education on canine vaccination.

Elizabeth supported Bea’s recent email to Michael Day and Pfizer Animal Health (January 2013)  with a call to the industry-funded WSAVA Vaccination Guidelines Group to publicly provide an objective, simple and effective message on vaccination to pet owners.
