THREE KEY ELEMENTS
Structure-based design leads to stable prefusion antigen conformation, generating broad and potent neutralizing antibody response as well as robust T-cell response.
A multilayered protein nanoparticle displays 20 stabilized trimers or 60 monomers on the surface (45-70 nm), similar to the HPV vaccine (~60 nm), the most efficacious VLP vaccine.
Our unique bio-manufacturing process makes complex nanoparticles in a one-step expression and three-step purification process, resulting in high-quality vaccines.
