There are hundreds of protocols to choose from. Some are very close to each other. Dogs do not need annual boosters, but some vets don't stop them for whatever reason (revenue, concerns over the research done, etc.). It's really something that you and the vet have to come to an agreement on because they can refuse to hospitalize your Yorkie if you don't follow their protocol. If they won't alter the schedule, then there are plenty of other vets who will. Most are stiill going to be uncomfortable with no vaccines after the one year booster though. They will sooner go for the AAHA protocol (one year booster and then every three years).
