I think the way the vaccination process can be done (excluding rabies) is basic puppyshots (though less of the combos that may not be needed, or giving things seperately rather than combined such as a 5 way rather than 7 way, doing lepto seperately), then a booster at one year.
I would not ever reccommend doing a puppy just 1 time. Often, maternal antibodies are still functioning in a younger pup, these actually fight the vaccination, Then as they fade out, the pup has no protection. I was told that pups should be weaned for at least 2 weeks prior to their first shot, but wouldn't have really developed antibodies until after their second shot.
Michelle, for TDI, my vet gave the standard vaccines, but wrote that he was following the 3 year protocol. They didn't complain about that, but this is her first year w/TDI, and she was vaccinated this year.
