Pa state law requires Rabies vaccine to be made current every 3 years. recently the distemper, parafluenza, parvo vaccine can be given every 3 years after puppy shots have been given at proper intervals of 6,9,12,and 16 weeks, then given at 1 yr of age. Where I work we give 1 or 2 vaccines at one time, then do other vaccines such as lyme or bordatella (kennel cough) 1-2 weeks later. Vets are really taking a close look at how much in the way of vaccines is too much. We have titred dogs who have received several doses of lyme vaccine over several years and some are still immune while others no longer are just a year from last vaccine. It seems to be an individual thing as to how often some vaccines need to be given.
