That is SO odd! :scratch: The holistic vet in the area recommends people use the PureVax only every three years (before the research was out - it's NOT a required vaccine by law in our county (!) ), and the best traditional vet in the area doesn't even carry the adjuvanted vaccine, only the PureVax, even though they still stick with the "vaccinate every year" routine (but have no problem if people don't want to vaccinate after that initial and one-year booster).
