When I was getting the rabies vaccine, I had to be monitored more carefully and had an adjusted time for each following injection (3 total). I also saw a immunization specialist at the transplant hospital regarding this since local center had no idea if I could be vaccinated. This was a school requirement, so investigating whether I could have it or not led me back to the transplant hospital. You may or may not want to do this due to cost, but it is a saftey issue.
