Thanks so much for your post. Great to see you here again!
Yes, the one year and three year vaccines are identical. The idea of requiring a booster in 1 year is to ensure an adequate immune response. If there was “proof” that he was vaccinated previously, then the vaccine he recently received probably could be re-certified to last for 3 years.
No, the very recent (published in the 1/15/15 JAVMA) scientific evidence shows that the overdue immune response is just as good as any other dog receiving the booster.
Unfortunately, most vets will require a direct vaccine problem or more serious issue to apply for a waiver.
No. Thuja is not a post-vaccine panacea (unless your dog entered a Thuja state after vaccination). Despite what some believe and even promote. Sorry.
