The only way to tell would be to do titers. It is usually thought that at least one or two modified live virus vaccines have to be given after the immune system is fully mature (maybe about 6 months) for life time immunity. Some vets would not agree though. They would say we have to revaccinate and revaccine.
I am not saying that people should only give one vaccine and hope it works for the life of the pet but it is likely that it would be sufficient. The same isn't true for killed vaccines (like rabies).
