HanaVax is a drug discovery venture that develops next-generation nasal vaccines.In addition to systemic immunity, nasal vaccines that can induce mucosal immunity to the respiratory mucosa, which is the entry point for pathogens, are considered the most effective vaccines for respiratory infections. Nanogel is a cholesterol pullulan that has
already been confirmed to be safe in humans, and can induce mucosal immunity more effectively by cationization. Induction of both systemic and mucosal immunity by effectively delivering vaccine and adjuvant to immunocompetent cells by encapsulating the vaccine antigen alone or in a nanogel with an adjuvant and introducing it into the mucosa via nasal administration It is a system that can do it. Vaccine adjuvant encapsulated in cationized nanogels is easily taken up by epithelial cells. The cationized nanogel acts as an artificial molecular chaperone to maintain the structure of the vaccine, efficiently delivering vaccine antigens to dendritic cells below the basement membrane of epithelial cells, effectively presenting the antigens to the immune system, and generating a strong immune response. Induces both mucosal and systemic systems. In other words, the cationized nanogel nasal delivery system elicits the two-stage protective immunity of humans and prevents the development of infectious diseases.
