Abstract: The present invention relates to a method of drying biological and other labile samples so that they can be preserved as a highly viscous liquid. The method involves the steps of preparing a preservation sample by dissolving/suspending an active agent in a solution of a stabilizing agent, subjecting the preservation sample to such temperature and pressure conditions that the preservation sample loses solvent by evaporation without freezing or bubbling to form a foam and removing solvent until the preservation sample dries to form a highly viscous liquid.

Abstract: The present invention relates to immunogenic compositions comprising a dried solid or highly viscous liquid formulation of inactivated polio virus (IPV) and a stabilizing agent wherein the IPV retains its antigenicity and/or immunogenicity. Methods of producing a dried formulation of IPV which retains its antigenicity/immunogenicity are described.

The stabilizing solution comprises a glass forming polyol and a second component which decreases the flow rate of the highly viscous liquid formed by the method.
