Abstract
A method is described for preparing an antigenic product which incorporates exposing an aerosol of a microbial suspension to temperatures at which substantially only the heat stable components of the microbial suspension which retain their immunogenic properties remain. More specifically, the aerosol is exposed to an elevated temperature which denatures all labile components and removes the liquid portion of the aerosol by evaporation.
