Hi Toni,
I'd tell them you understand it's the law, and you still know it's foolish law, not based on immunology at all. If you're confident that immunity is long lasting (read Vaccinations: Efficacy if you doubt it), you can tell them you've fulfilled the intent of the law but will not follow the letter of the law, risking your animal's health.
They are not law enforcement. That's important to understand. Tell them you'll deal with the law if it comes to you, but you'd like written on each one's records: NO FURTHER VACCINATIONS.
p.s. To really understand this, drop the word "vaccination" into the search box and sit back and read for a while. This is your most important decision on behalf of your animals, bar none.
