METHOD OF INACTIVATING MICROORGANISMS

摘要

This invention provides methods of inactivating a microorganism and preparing a vaccine including the step of applying to said microorganism a cross-linking agent simultaneously with a separate inactivant. This invention further relates to vaccines prepared by such methods and a kit including such inactivated microorganism. The cross-linking agent is typically formaldehyde (FA) and the inactivant typically binary ethyleneimine (BEI).
