High titers of NAbs and a strong TH1 skewing and cellular immune response were observed in vaccinated animals, and a phase 2/3 clinical trial is ongoing (NCT04683224).[148] EpiVacCorona contains three chemically synthesized peptide antigens of the SARS‐CoV‐2 S protein, and epitopes that may cause antibody‐dependent enhancement (ADE) of infection are deliberately avoided. This evidence concerns the gene PROS1 and infection.
