General information

RBD-12GS-I53-50 is a candidate vaccine. It uses the SARS-CoV-2 spike protein RBD residues 328–531 as an immunogen multivalently displayed on "I53-50" protein nanoparticle (Walls et al., 2020).

Elicited significantly stronger antibody (anti-spike and neutralizing) responses in mice and pigtail macaques, especially after second immunization, compared to RBD or spike trimer vaccination only. The antibody response was targeting non-overlaping RBD sites. The vaccine candidate provided protection from mouse-adapted SARS-CoV-2 in murine lungs and nasal turbinates.
