See my post on over vaccinating:

IMO, your puppy should at least get all his puppy shots and 1st set of boosters. He needs to build up his immunity somehow.... After that, I would do a titer test. If the test shows he has the antibodies for a particular virus he shouldn't need to be revaccinated. Over vaccinating can do more harm than good (it's been linked to seizures, tumors and liver/kidney disease and arthritis among other things). Google
Vaccinosis for a bit of reasearch.
I would talk it over with your vet and decide what the best course of action is for your pup. No two dogs are alike, and while my decision to perform titer tests instead of automatically re-vaccinating works for us, it might not for you....
