my son was administered full five injection course of anti rabbiesthis year only now again he is bit by our own dog who is fully vaccinated could you please tell me(a) how long the effect of full dose of anti rabies vaccine lasts is it life time or one year or even less(b) if the dog in question is vaccinated then in that case do we need a vaccination.
Thanks for contacting ChatDoctorI am sorry to hear that your son was bitten by his dog. Since your dog has also been vaccinated from rabies there is no reason to revaccinate your son. If thought in the future your son is bitten by a dog or animal that may have rabies he will need to have an additional 2 injections to insure proper antibody levels. At this time there has never been a documented case of rabies after being immunized with the rabies vaccine. Hope this answers your question.
