They claim to be the world's first "second generation broadly protective" recombination protein subunitvaccine, i.e. by combining three heterogeneous antigens into one single trimer RBD protein (突变集成三聚化RBD, mutI-tri-RBD).[4] It's based on the original, and the Beta (K417N/E484K/N501Y) and Kappa (L452R/E484K) variants.[5]
