摘要

Ionizing radiation, β-propiolactone, and acetylethyleneimine were compared for their ability as virus-inactivating agents for the preparation of rabies vaccine. Each agent reduced viral infectivity exponentially; ionizing radiation also destroyed viral hemagglutinin. The vaccine prepared by ionizing radiation was equal or superior to that prepared by β-propiolactone in its ability to protect mice from rabies infection. The acetylethyleneimine-treated vaccine was a less potent immunogen.
