مستخلص: The newly identified XBB.1.16-containing sublineages, including XBB.1.5, have become the prevailing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant in circulation. Unlike previous Omicron XBB variants (e.g., XBB.1.5 and XBB.1.9) harboring the F486P substitution, XBB.1.16 also carries a T478R substitution in the receptor-binding domain (RBD). Numerous researchers have delved into the high transmissibility and immune evasion of XBB.1.16 subvariant. Therefore, developing a new vaccine targeting XBB.1.16, including variants of concern (VOCs), is paramount. In our study, we engineered a recombinant protein by directly linking the S-RBD sequence of the XBB.1.16 strain of SARS-CoV-2 to the sequences of two heptad repeat sequences (HR1 and HR2) from the SARS-CoV-2 S2 subunit. Named the recombinant RBD XBB.1.16 -HR/trimeric protein, this fusion protein autonomously assembles into a trimer. Combined with an MF59-like adjuvant, the RBD XBB.1.16 -HR vaccine induces a robust humoral immune response characterized by high titers of neutralizing antibodies against variant pseudovirus and authentic VOCs and cellular immune responses. Additionally, a fourth heterologous RBD XBB.1.16 -HR vaccine enhances both humoral and cellular immune response elicited by three-dose mRNA vaccines. These findings demonstrate that the recombinant RBD XBB.1.16 -HR protein, featuring the new T478R mutation, effectively induces solid neutralizing antibodies to combat newly emerged XBB variants.
