I will be planning to vaccinate every three or so years after the first years booster. Hopefully with an increase availability of titre testing the necessity for vaccination will be kept to an absolute minimum and state of health as high as is possible. The law (Victorian at least) is that dog that attend boarding kennels and training establishments (even if a 1on1 at the dog owners home - how silly!!!) have their full C5 each year. I recently enquired with the department of primary industries in Victoria as to whether there could be a change to this law considering the available evidence and that the major vet hospitals in America are now adopting a 3yr booster scheme. I got a reply asking what my motives/reasons for this were. I responded with some of the evidence and directing them to some useful websites and they eventually responded that they would look further into the matter by contacting the AVA and also the producers of the vaccinations as well. I will be following this up (several times I'm sure) to hopefully get a result. I urge anyone who feels the same to contact (email, letter, call etc) their state department for natural resouces and environment and query the law and ask for the change. The more people asking the more likely it will happen.
Cheers
