ABSTRACT:
This invention relates to a process for preparing vaccines, which consists in bringing into contact a toxic product with glutaraldehyde at a concentration and for a duration just sufficient to detoxify or inactivate said toxic product, and in stopping the glutaraldehyde-antigen reaction as soon as said inactivation stage is reached by physical and/or chemical means. The thus obtained inactivate product remaining antigenic and retaining its immunizing power, is usable as a vaccine for the preventive treatment of human and animals against infection caused for example by microbial or venomous toxins.
