This is indeed good news, Raven!
And there's another tip in your comment, useful to others: if there's a weak link in the chain that helps you achieve no further vaccines, USE IT to your advantage. So, not all places that take therapy dogs check on county requirements. Great. You're in.
We have to be creative and a bit subversive sometimes in the name of what we know is right, and to protect our animals! If you know your animals to be previously vaccinated, (and therefore immune, bonus if you have a titer to prove it), you don't need to bring up county requirements as you enter into therapy work, right? Same with raw feeding. Salmonella appears in kibble as well, you know.
More often, less said is better! Assume a dominant, but friendly role and get things done without risking your animals' Vital Animal status. Here's an earlier post on attitude to help you do this.
Carry on! March forth with exemplary shiny magnets of health and change the world, one conversation at a time!
