Abstract

Prototype DNA vaccines for SARS-CoV-2: The development of a vaccine to protect against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an urgent biomedical need. Yu et al. designed a series of prototype DNA vaccines against the SARS-CoV-2 spike protein, which is used by the virus to bind and invade human cells. Analysis of the vaccine candidates in rhesus macaques showed that animals developed protective humoral and cellular immune responses when challenged with the virus. Neutralizing antibody titers were also observed at levels similar to those seen in humans who have recovered from SARS-CoV-2 infection. Science , this issue p. 806

  • In rhesus macaques immunized with DNA vaccine candidates, titers between 1:60 and 1:200 correlated with complete protection from disease.

    “titers between 1:60 and 1:200 correlated with complete protection from disease.”

    From An <i>Alphavirus</i> -derived replicon RNA vaccine induces SARS-CoV-2 neutralizing antibody and T cell responses in mice and nonhuman primates (2020) · cites this paper as [53]

    The Immune correlates of vaccine-induced protection section reports higher neutralizing-antibody titers in completely protected than partially protected vaccinated macaques; it defines complete protection as no detectable sgmRNA after challenge. The paper does not identify titers of 1:60 to 1:200 as a range associated with complete protection. The titers of 74 and 170 reported in Construction and immunogenicity are group medians, not protection thresholds (pages not specified in our copy). (LLM, conf=0.88)

  • LION/repRNA-CoV2S elicited modest but detectable T cell responses in macaques, consistent with previous studies of SARS-CoV-2 S-targeted DNA and live viral vector vaccines tested in nonhuman primates.

    “Our findings demonstrate that LION/repRNA-CoV2S elicited modest but detectable T cell responses in macaques (Fig. 5), an outcome that is consistent with previous studies of SARS-CoV-2 S-targeted DNA and live viral vector vaccines tested in nonhuman primates (53, 58).”
  • Binding and neutralizing antibody titres are important correlates of protection for these SARS-CoV-2 vaccines in non-human primates.

    “Consistent with prior observations from our laboratory and others15,16,22, these findings suggest that binding and neutralizing antibody titres are important correlates of protection for these SARS-CoV-2 vaccines in non-human primates.”
  • In rhesus macaques given DNA vaccine candidates expressing different forms of the SARS-CoV-2 spike protein, post-vaccination neutralizing antibody titers were correlated with protection against SARS-CoV-2 challenge.

    “In rhesus macaques given DNA vaccine candidates expressing different forms of the SARS-CoV-2 spike protein, post-vaccination neutralizing antibody titers were correlated with protection against SARS-CoV-2 challenge.17”

    From An mRNA Vaccine against SARS-CoV-2 — Preliminary Report (2020) · cites this paper as [17]

  • In early rhesus macaque vaccine studies, spike-directed neutralizing antibody levels were the strongest correlate of protection.

    “In early studies of SARS-CoV-2 vaccine candidates in a rhesus macaque model, the amount of NAbs directed at the S protein, which mediates cellular binding, emerged as the strongest correlate of protection10,30.”

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.
