Heat Biologics Inc. unveiled its new RapidVax? cellular vaccine platform at the 2021 World Antiviral Congress. RapidVax is designed as a rapid programmable vaccine to target a comprehensive range of emerging biological threats. Heat is showcasing a poster presentation highlighting RapidVax at the World Vaccine & Immunotherapy Congress West Coast and World Antiviral Congress, November 30 to December 2, 2021. RapidVax is designed to enable an accelerated response to a wide variety of infectious agents by providing a flexible ?plug and play? vaccine platform that can be stockpiled in advance, and then rapidly customized, manufactured, and deployed to address imminent and future biological threats. This platform has the potential to shorten the timelines needed to develop and test novel vaccines against emerging infectious agents. RapidVax leverages the immune-activating properties of heat shock protein gp96, a danger-signal associated protein. This protein normally chaperones activation peptides to antigen-presenting cells under cellular stress. These peptide-gp96 complexes then stimulate antigen cross-presentation, leading to a broad array of innate and adaptive immune responses to confer cellular and humoral immunity against a wide range of pathogens. RapidVax also co-expresses a potent T-cell costimulatory molecule, OX40L, which contributes to the generation of long-lasting T-cell memory and B-cell neutralizing antibody production via the development of T follicular helper cells upon enhanced stimulation of professional antigen-presenting cells.
