Abstract

Although most mutations in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genome are expected to be either deleterious and swiftly purged or relatively neutral, a small proportion will affect functional properties and may alter infectivity, disease severity or interactions with host immunity. The emergence of SARS-CoV-2 in late 2019 was followed by a period of relative evolutionary stasis lasting about 11 months. Since late 2020, however, SARS-CoV-2 evolution has been characterized by the emergence of sets of mutations, in the context of 'variants of concern', that impact virus characteristics, including transmissibility and antigenicity, probably in response to the changing immune profile of the human population. There is emerging evidence of reduced neutralization of some SARS-CoV-2 variants by postvaccination serum; however, a greater understanding of correlates of protection is required to evaluate how this may impact vaccine effectiveness. Nonetheless, manufacturers are preparing platforms for a possible update of vaccine sequences, and it is crucial that surveillance of genetic and antigenic changes in the global virus population is done alongside experiments to elucidate the phenotypic impacts of mutations. In this Review, we summarize the literature on mutations of the SARS-CoV-2 spike protein, the primary antigen, focusing on their impacts on antigenicity and contextualizing them in the protein structure, and discuss them in the context of observed mutation frequencies in global sequence datasets.

  • D614G is associated with increased transmissibility, infectivity, and viral load, making Lambda more lethal.

    “D614G is again associated with the increase in transmissibility, infectivity, and viral load, making the Lambda variant even more lethal [55].”

    From Waves and variants of SARS-CoV-2: understanding the causes and effect of the COVID-19 catastrophe (2022) · cites this paper as [55]

    The Introduction and Structural context of spike mutations sections (page numbers unavailable) report a moderate infectivity advantage and increased transmissibility associated with D614G. They do not establish increased viral load or that D614G makes the Lambda variant more lethal. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • Mutations in the spike protein and RBD have been shown to affect antibody neutralisation and thus reduce vaccine-induced immunity.

    “Mutations in the spike protein and RBD have been shown to affect antibody neutralisation and thus reduce vaccine-induced immunity [22].”
  • The paper says Lambda is more resistant to neutralization by convalescent sera and the Alpha variant than the parent D614G spike protein.

    “The Lambda variant spike protein is found to be 3.3 times more resistant to neutralization by the convalescent sera than the parent D614G spike protein and 4.9 times to that of the Alpha variant ones.”

    From Waves and variants of SARS-CoV-2: understanding the causes and effect of the COVID-19 catastrophe (2022) · cites this paper as [55]

    The Variants of interest or concern section discusses modest reductions in neutralization of Alpha (B.1.1.7) by convalescent sera, but does not compare it with Lambda. Searches for Lambda and the claimed 3.3-fold and 4.9-fold comparisons found no passage addressing those results in our copy. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Reduced sensitivity of SARS-CoV-2 variants to antibody and serum neutralization has been widely observed.

    “However, reduced sensitivity of SARS-CoV-2 variants to antibody and serum neutralization has been widely observed (18–21).”
  • The receptor binding domain and N-terminal domain are immunodominant targets of neutralizing antibodies elicited by COVID-19 vaccines or SARS-CoV-2 infection.

    “both being immunodominant targets of neutralizing antibodies elicited by COVID-19 vaccines or by SARS-CoV-2 infection (5, 6).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
