Abstract

Immunity from reinfection: One of the many open questions about severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is whether an individual who has cleared the virus can be infected a second time and get sick. Chandrashekar et al. and Deng et al. generated rhesus macaque models of SARS-CoV-2 infection and tested whether natural SARS-CoV-2 infection could result in immunity to viral rechallenge. They found that animals indeed developed immune responses that protected against a second infection. Although there are differences between SARS-CoV-2 infection in macaques and in humans, these findings have key implications for public health and economic initiatives if validated in human studies.

  • Neutralizing antibody titres elicited by CV2CoV to viral variants exceeded the values previously reported as threshold titres for protection (50-100).

    “Although our challenge virus in this study was SARS-CoV-2 WA1/2020, the neutralizing antibody titres elicited by CV2CoV to viral variants exceeded the values we previously reported as threshold titres for protection (50–100)17,19,22.”

    From Optimization of non-coding regions for a non-modified mRNA COVID-19 vaccine (2022) · cites this paper as [17]

    The Virology and immunology section reports neutralizing antibody titres of about 100 in infected rhesus macaques, which were subsequently protected against rechallenge. But the Discussion explicitly says the study could not determine immune correlates of protection; it does not establish 50–100 as a protective threshold. The cited paper also does not report CV2CoV titres against variants, which are results of the citing study rather than a finding attributed to this source. (LLM, conf=0.88)

  • Humoral and cell-mediated immune responses have been associated with vaccine-induced protection against challenge or subsequent rechallenge after SARS-CoV-2 infection in a rhesus macaque model.

    From An mRNA Vaccine against SARS-CoV-2 — Preliminary Report (2020) · cites this paper as [19]

  • In macaques, primary SARS-CoV-2 infection protects against subsequent viral challenge for at least 28-35 days, with re-exposure boosting binding and neutralizing antibodies and IFNγ secretion by T cells.

    “Initial studies in macaques showed that a primary infection with SARS-CoV-2 protects against subsequent viral challenge for at least 28–35 days, with re-exposure driving memory immune responses that included boosting of binding and neutralizing antibody levels as well as of IFNγ secretion by T cells46,47.”
  • 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.”
  • Preexisting immunity to SARS-CoV-2 is associated with protection against reinfection in humans and in nonhuman primates.

    “Preexisting immunity to SARS-CoV-2 is associated with protection against reinfection in humans (9–11) and in nonhuman primates (12, 13).”

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.
