Abstract The evolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to challenge the efficacy of vaccination efforts against coronavirus disease 2019 (COVID-19). The Omicron XBB lineage of SARS-CoV-2 has presented dramatic evasion of neutralizing antibodies stimulated by mRNA vaccination and COVID-19 convalescence. XBB.1.16, characterized by two mutations relative to the dominating variant XBB.1.5, i.e., E180V and K478R, has been on the rise globally. In this study, we compare the immune escape of XBB.1.16 with XBB.1.5, alongside ancestral variants D614G, BA.2, and BA.4/5. We demonstrate that XBB.1.16 is strongly immune evasive, with extent comparable to XBB.1.5 in bivalent-vaccinated healthcare worker sera, 3-dose-vaccinated healthcare worker sera, and BA.4/5-wave convalescent sera. Interestingly, the XBB.1.16 spike is less fusogenic than that of XBB.1.5, and this phenotype requires both E180V and K478R mutations to manifest. Overall, our findings emphasize the importance of the continued surveillance of variants and the need for updated mRNA vaccine formulations.

Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
  • Immune: The article focuses on the study of mutations and immune.
  • Target Gene: Host genes that viral mutations may affect.
Clinical and Epidemiological Correlations
