<p>Processes for the production of a stabilised vaccine composition of labile immunogens, wherein a fluid comprising one or more immunogens is sprayed into a reactor containing fluidised particles of a pharmaceutically acceptable water soluble material at a temperature of about 25° C. to about 50° C., such that the immunogen coats and is dried onto the particles under the fluidising conditions, and thereafter collecting from said reactor dried immunogen containing particles having a moisture content between about 0.1% w/w to about 10% w/w are described. Also described are stabilised vaccine compositions of labile immunogens.</p> |
