## Abstract

We are amending the regulations pertaining to the standard requirements for rabies vaccine, killed virus, so that they incorporate the latest edition of a guide to laboratory techniques. The regulations currently refer to the previous edition of that guide, which was published in 1973. This action will ensure that the latest edition of the guide is incorporated by reference and used in conducting potency tests during the production of inactivated (killed) veterinary rabies vaccines.
