It is recommended that only one type of rabies vaccine be given, and it is perfectly fine if the type of rabies vaccine does not change when you change locations. However, it is still important to time the rabies vaccination as well as possible. If this time is advanced or delayed by a few days, it may slightly affect the effectiveness of the rabies vaccination. Rabies vaccine is basically considered to be okay if the type of vaccine is changed, but if all the vaccines are given using the five-dose method or the four-dose method. Although no clinical tests have been done to show whether the change in vaccine type has an effect on the production of rabies neutralizing antibodies, it is mostly believed that the effect would not be particularly large and would still allow the rabies vaccine to have the appropriate effect. If you are particularly concerned, you can go to an institution that has the ability to test for rabies neutralizing antibodies to test for the amount of rabies neutralizing antibodies.
