There is information and research available from breeders in North America that says puppies are protected via their mother for the first few weeks of life, but do keep them away from unknown dogs (aka..un-vaccinated) during this time. Then when their own immune system begins to kick in, give their first vaccinations at 20 weeks. Followed by one-time boosters, these dogs then have blood titre testing for the rest of their lives, which prove they are still protected! No more dangerous vaccination protocols year after year. In North America however, in many jurisdictions, a 2 or 3-yr rabies vac may be required by municipal law.
Our own "old school" veterinarian has agreed that one of our dogs will no longer have immunizations except rabies for, likely, the rest of her life (she is 4), as she reacts every time from immunizations with diarhhea, long term itching, and general malaise. Her skin turns pink for weeks! This same vet actually said that "we have been over-immunizing our pets for years, and if given their first series, followed by boosters, they should be fine for years." I almost fell over when I heard him admit to this. I'm sorry, I forget the names of the kennels that were included in the research mentioned in my first sentence, but digging around with the right key words on the web will bring up fascinating stuff. Go with the info from responsible sources. They will be long time professional kennels, and research from universities. Good luck, and stick to your guns!!
