Yes it has to be given in either arm or thigh...It's ok for the first dose now..From second dose on wards get it in thigh.

Yes Rabies vaccine should not be administered in the gluteal region because it may not produce enough antibodies given from that area. For children any injection or vaccination it's better to administer in the anterolateral thigh region because the risk of foot drop is more with gluteal region administration. You can repeat the Rabies vaccine once and take it as 0 dose.
