First things first. You did the right thing by getting TT administered and also asked for the Anti rabies vaccine
. Was the vaccine given in your buttocks or thigh ? It is not advisable to administer rabies vaccine in buttocks except deltoid for adults and anterolateral aspect of thigh for children. If you administer it in the buttocks , it does not result in adequate antibody titre response. So definitely , as per CDC guidelines you need to take it again in deltoid if you wish to be on the safer side. Is your pet vaccinated ? Or is is a stray dog you brought out of interest from the street ? In the latter case, observe the dog for at least 10 days from now. If it continues to remain healthy, you need not take any further dose of rabies vaccine.
