Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Epidemiological studies suggest that herd immunity through natural infection may not have been achieved even in high-infection communities, and that waning immunity plus antigenic variation may allow continued circulation.

    “epidemiological studies suggest that, even in communities with high infection rates, herd immunity through natural infection may not have been achieved, and these studies raise the possibility that a combination of waning immunity and viral antigenic variation may allow for continued circulation of the virus11,12.”
  • A seroepidemiological study in Manaus suggested the potential for reinfection beyond 6-8 months after infection.

    “A recent seroepidemiological study in the Brazilian city of Manaus has also suggested the potential for reinfection beyond 6–8 months after infection11,12,57.”
  • In a heavily exposed population in Manaus, seroepidemiological data point to possible reinfection susceptibility by 6-8 months.

    “This contrasts with the seroepidemiological evidence for ongoing spread of infection in a highly exposed population in Manaus, which suggests that there may be susceptibility to reinfection after 6–8 months11,12.”

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.
