(16)It is possible that rabies vaccines administered to pet animals of the species listed in Part A of Annex I before the age of three months do not induce protective immunity due to competition with maternal antibodies. Consequently, vaccine manufacturers recommend not to vaccinate young pet animals before that age. Therefore, in order to authorise the non-commercial movement of young pet animals of the species listed in Part A of Annex I that have not been vaccinated, or that have been vaccinated, but have not yet acquired protective immunity against rabies, this Regulation should establish certain precautionary measures to be taken and give the Member States the possibility to authorise such movement into their territory when young pet animals comply with those measures.
