[The phenomenon of "early and stimulated death" in mice infected and then vaccinated against rabies]. / Le phénomène de "mort précoce et stimulée" chez la souris infectée puis vaccinée contre la rage.

Live (diluted) and inactivated rabies vaccines of low antigen content induce early and enhanced death in mice, inoculated before vaccination with a wild type of rabies virus. Such vaccines, which neither induce interferon nor protect, produce a low level of antibodies which appear later than with vaccines of higher antigenicity. It is recommended to examine rabies vaccines not only by the usual (pre-exposure) potency test-NIH test or modified NIH test (one vaccination), but also by a post-exposure potency test.
