I expect a doctor could better answer your questions but, I understand that the Rabbies vac gives you extra time to find a doctor to beging the course of injections. I had to take a Japanese tourist to a clinic last year after he was bitten by a dog in northern greece. They began rabies shots immediately but they jabbed him in the arse not the stomach..I expect in Europe at least the Vacs are a little more sophisticated than a few years ago.
IMHO take your malaria pills, not fun.
