The incubation period for rabies is usually 1-3 months, and without rabies vaccination, if you have not had a rabies attack for more than three months, it is unlikely that you will have a rabies attack. However, in some cases, the incubation period may be close to one year, so it is safe to be more than one year before you can basically not worry about rabies attacks. For people who get rabies vaccine, the time is best to wait until all the rabies vaccine has been given before you can be sure that it is safe. Generally, when the third or fourth rabies injection is given, the rabies neutralizing antibodies in the body will have reached an effective concentration and safety can be determined at this time. If you are not sure and have the appropriate test available, you can have the neutralizing antibody concentration tested and be safe if it exceeds 0.5 IU/mL. If the rabies vaccine has not yet been administered at this time, it is still important to complete the rabies vaccine. It is likely that the rabies neutralizing antibodies will not last too long because they will only last for a longer period of time after the injection has been completed.
