This is a topic that has people strictly divided, and there is no way you will get a definitive answer. I suggest you do a 'search' (top right corner of the screen), typing in 'boosters', 'vaccinations' or 'nosodes', and study the posts.
Bear in mind that if you ever want to board your dog in commercial kennels it will (legally) need an up-to-date vaccination record.
