What are your feelings on vaccines?

I was wondering what the general consensus is on here concerning vaccines? Up until about two years ago I'd never given them much thought really...I always just went with what my vet recommended and assumed they knew what was best. I eventually started doing some research into vaccines and can't say that I really liked what I found...

My dogs are a small breed and indoors the majority of the time, I never board them, and I groom them myself. I am now of the feeling that once that have had all of their puppy shots and the first year adult boosters that I only have them vaccinated once every three years (as it's required by law here) for their rabies vaccination and have titer testing done yearly for the rest of their vaccinations. So far, their titer testing has not shown any of their other vaccination levels being low enough that requires "re-vaccination"

I've never had any horribly reverse reactions with any of my dogs concerning vaccines, I just, personally, don't feel good about giving them booster vaccines every year after the research I've done and I'm wondering if I'm in the minority here?

I'm not saying those of you who do vaccinate your dogs yearly are wrong by any means, I think it's a personal decision that you have to make for your own pet...I'm just wondering if there are any other people out there who feel pets are largely being over-vaccinated and have chosen not to vaccinate their pets yearly but to have titer testing done instead?
