Some rabies vaccines can be given as few as four doses, but this must be the 2-1-1 method of four doses. In the case of the five-dose rabies vaccine, only four doses can produce rabies antibodies, but this is not the way to do it according to the protocol. After the four shots, antibodies can be produced, but the amount of antibodies may not be as high as the five shots and may not last as long as the five shot method. Therefore, it is possible to prevent rabies with four injections, but it is not safe to do so. The rabies vaccine must be administered according to the appropriate protocol. If only four shots are given, the amount and duration of antibodies are generally not as good as the five shot method. In addition to rabies vaccination, you should also choose whether to inject rabies serum and immunoglobulin according to the level of exposure, and disinfect the bite or scratch wounds properly.
