Abstract
Immunologically intact protein or peptide immunogens are recovered from vaccines consisting of immunogen-aluminum hydroxide (alum) complexes. Recovery consists of dissolution of the complexes with an alkali metal salt of a carboxylic acid at a basic pH, reduction of the pH to physiological levels, removal of excess dissolvent and isolation of the protein or peptide immunogen.
