Hello! From your question, it doesn't appear that we live and work in the same country and furthermore I treat animals and not people; please note that any technical information about your health needs to come from your Doctor and not from a vet.
Rabies may have a very slow onset - I believe that it has to work its way along the nervous system - which means that clinical signs can occur a long time after a bite. Even in humans, an absence of clinical signs a few weeks after a bite may not mean that there will be no consequences in the future. However, as I said, I am not your Doctor and have no up to date understanding of how the Rabies vaccination works in the human. It is your Doctor's job to know the risks and how to avoid them and would strongly advocate taking their advice.
I only know that in animals, if a vaccine course is not completed, it cannot be guaranteed to work and this would, for example, completely invalidate the pets' health insurance should there be problems further down the line.
