Given the high risk involved with pet vaccinations you'd be far better off doing a test for the antibodies rather than assuming another vaccine is required.

Depends on the vaccine, for example vaccine-induced Mumps antibodies disappear within 2 years, whereas vaccine-induced Measles antibodies can last up to 10. Women only stay fertile for a set amount of time, those HCG antibodies will stop them giving birth at least in their most fertile years.
