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.

  • 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.”
  • 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).”
  • In two nonhuman primate studies, animals previously infected with SARS-CoV-2 were protected against high-dose re-challenge one month later, and protection was associated with neutralizing antibodies.

    “Animals infected with SARS-CoV-2 were protected from a high dose re-challenge with SARS-CoV-2 1 month later, and protection was associated with neutralizing antibodies”

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.
