Over-vaccination of dogs with unnecessary ‘boosters’

pet vaxFor those people interested in the ongoing over-vaccination of pets scandal, I recently forwarded a letter to Professor Ronald Schultz, a member of the World Small Animal Veterinary Association’s Vaccination Guidelines Group, and the American Animal Hospital Association’s Canine Vaccination Task Force, complaining about the confusing and misleading use of the term ‘booster’ in vaccination guidelines.

The email below summarises my complaint.  My detailed letter can be accessed via this hyperlink:  Letter to Professor Ronald Schultz re confusing and misleading use of the term ‘booster’

Professor Schultz

Please see attached a detailed letter addressed to you criticising the use of the confusing and misleading term ‘booster’ in vaccination guidelines issued by the WSAVA Vaccination Guidelines Group.  This criticism is also relevant to the 2011 AAHA Canine Vaccination Guidelines.

As noted in my letter, I suggest use of the term ‘booster’ in relation to canine core modified live virus (MLV) vaccines for parvovirus, distemper virus and adenovirus is resulting in extensive unnecessary over-vaccination of already immune dogs.

I suspect that many pet owners are still not being informed that there is no evidence to support revaccination of already immune animals with so-called ‘booster’ shots, nor that there is the option of titre testing to verify a response to core MLV vaccination.

This is especially concerning in light of the WSAVA 2010 guidelines warning “that we should aim to reduce the ‘vaccine load’ on individual animals in order to minimize the potential for adverse reactions to vaccine products”, and the WSAVA 2013 guidelines advice that “it is important to give as few vaccines as possible…” and “…any reaction to a vaccine that is not needed is unacceptable”.

There are serious flaws in the WSAVA guidelines 2010 and 2013 which must be rectified.  In addition, the 2011 AAHA Canine Vaccination Guidelines should also be subjected to review.

I request your urgent response on this matter.
