Abstract

Multiple severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants that have mutations associated with increased transmission and antibody escape have arisen over the course of the current pandemic. Although the current vaccines have largely been effective against past variants, the number of mutations found on the Omicron (B.1.1.529) spike protein appear to diminish the protection conferred by preexisting immunity. Using vesicular stomatitis virus (VSV) pseudoparticles expressing the spike protein of several SARS-CoV-2 variants, we evaluated the magnitude and breadth of the neutralizing antibody response over time in individuals after infection and in mRNA-vaccinated individuals. We observed that boosting increases the magnitude of the antibody response to wild-type (D614), Beta, Delta, and Omicron variants; however, the Omicron variant was the most resistant to neutralization. We further observed that vaccinated healthy adults had robust and broad antibody responses, whereas responses may have been reduced in vaccinated pregnant women, underscoring the importance of learning how to maximize mRNA vaccine responses in pregnant populations. Findings from this study show substantial heterogeneity in the magnitude and breadth of responses after infection and mRNA vaccination and may support the addition of more conserved viral antigens to existing SARS-CoV-2 vaccines.

  • Due to greater vaccine escape of Omicron variants, the cross-neutralizing titre against the Omicron variant is several folds lower than against WT, therefore the decline rate is much faster.

    “In addition, due to a greater vaccine escape of Omicron variants, the cross-neutralizing titre against the Omicron variant is several folds lower than against WT, therefore the decline rate is much faster 15 .”

    From Safety and immunogenicity of a prefusion non-stabilized spike protein mRNA COVID-19 vaccine: a phase I trial (2022) · cites this paper as [15]

    The Results section reports reduced Omicron neutralizing titers relative to D614 and describes fold reductions after vaccination (Fig. 2C). It also reports that titers against all variants waned by day 210 after two vaccine doses, but does not establish that Omicron titers declined faster than WT titers or that a lower starting titer caused a faster decline. (LLM, conf=0.87)

  • Due to escape of the Omicron variant from current approved vaccines, the efficacy of all current vaccines is reduced and a new variant-specific analysis is required.

    “However, due to escape of the Omicron variant from current approved vaccines, the efficacy of all current vaccines is reduced and a new variant-specific analysis is therefore required [13][14][15] .”

    From Safety and immunogenicity of a prefusion non-stabilized spike protein mRNA COVID-19 vaccine: a phase I trial (2022) · cites this paper as [15]

    The Results report reduced neutralizing antibody responses against Omicron after mRNA vaccination, and the Discussion says mRNA vaccines will likely have somewhat reduced effectiveness against variants as antigenically drifted as Omicron. The paper does not establish reduced clinical efficacy for all current vaccines; it studies neutralization after mRNA vaccination. Its Introduction motivates variant-specific assessment, but does not say that a new analysis is required. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Neutralizing antibody against WT and Omicron induced by 2 doses of approved COVID-19 vaccines wane over time.

    “One of the limitations of currently approved mRNA COVID-19 vaccines is that recent data have shown that the neutralizing antibody (NAb) against WT and Omicron induced by 2 doses of approved COVID-19 vaccines wane over time.”

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.
