Compositions, methods and uses for thermally stable multi-targeted antigens
Embodiments of the present invention provide for novel compositions and methods for making and using a thermally stable human papilloma virus (HPV) formulation or other stabilized multimeric virus formulation. Certain embodiments concern lyophilizing HPV formulations in the presence or absence of adjuvants. Other embodiments concern lyophilizing HPV capsomere vaccines in order to increase stability of an immunogenic composition against HPV infection for storage, delivery and use. In yet other embodiments, a single immunogenic composition can include a thermally stable formulation of multiple virus serotypes. Yet other embodiments disclosed herein concern multi-targeted antigen complexes lyophilized in formulations of use to prolong stability and/or enhance immunogenicity. Other embodiments concern exposing lyophilized multi-targeted antigen complexes to elevated temperatures to enhance immunogenicity of the antigens of the complex to multiple pathogens.
