  • Patent number: 10772947
    Abstract: The invention provides human papillomavirus (HPV) antigen formulations which show increased antigen stability. More specifically, the invention provides stable HPV formulations comprising HPV virus-like particles (VLPs) bound to an aluminum salt adjuvant and further comprise a combination of sucrose and mannitol. The vaccine formulations of the invention are stable following freeze-thaw and freeze-drying. Also provided are lyophilized and frozen HPV vaccine formulations comprising HPV VLPs of at least one HPV type adsorbed onto an aluminum salt adjuvant, sucrose, and mannitol. Methods of making the stable vaccine formulations of the invention are also provided.

  • Patent number: 10449243
    Abstract: The present invention relates to dengue virus vaccine compositions comprising a first and a second dengue vaccine, wherein the first dengue vaccine comprises at least one live, 5 attenuated dengue virus or live, attenuated chimeric dengue virus and the second dengue vaccine is a recombinant dengue subunit vaccine, a DNA vaccine, a conjugate vaccine, or an inactivated dengue vaccine; wherein the genome of the live attenuated dengue virus or the live attenuated chimeric dengue virus comprises a 30 nucleotide deletion of the TL2 stem-loop structure of the 3? untranslated region. The dengue virus vaccine compositions of the invention may further 10 comprise one or more adjuvants. In preferred embodiments of the invention, the first and the second dengue vaccine are tetravalent.
