You can ask your vet to do titer tests to see if your pet has immunities for the diseases he is supposed to be annually vaccinated for. If your pet has the antibodies, don't get your pet revaccinated. If he doesn't have antibodies, get the vaccine to build antibodies.
A lot of people think vaccinations are like some sort of a magic protector. They are just small doses of the illness that are supposed to get the dog's immune system familiar with the illness, build antibodies, so your dog's body can fight the "real" disease later.
If you disagree with your vet's view of vaccinations, find a vet you are comfortable with. It may be difficult to find a vet that is willing to listen to your concerns without dismissing them and explain things you may not know about, but they exist. We recently switched vets, and our new vet is more up to date with "contemporary" vaccination protocol and I cannot explain how happy I am. I know my vet is not vaccinating my dogs just for giggles because he explains why he chooses to vaccinate my pet for certain things and when these vaccinations are needed. When I do research, I discuss it with him, and trust me, no matter how well you research things, there are a couple of important details you miss. I trust our vet completely. I think it's very important to be able to trust one's vet, for the sake of the animal and for one's own mental well-being as well.
