Recent advances in the preparation of antirabies vaccines containing inactivated virus.

This paper describes experiments undertaken to determine the usefulness of 15 nitrogen-mustard and mustard-like drugs in inactivating fixed rabies virus for the preparation of experimental antirabies vaccines. One or more of the five agents eventually selected gives promise of practical value in rendering rabbit-brain fixed rabies virus and duck-embryo fixed rabies virus noninfective for mice, at the same time allowing of successful antirabies immunization.
