Abstract

To the Editor: In the Food and Drug Administration (FDA)-mandated safety trial by Ytterberg et al., patients who were treated with tofacitinib had a higher incidence of cancer than those treated with a tumor necrosis factor (TNF)

  • Omicron does not induce relevant cross-protective neutralizing antibody titres in SARS-CoV-2 naïve populations.

    “Unfortunately, while Omicron appears to cause less severe disease than other variants4, it does not induce relevant cross-protective neutralizing antibody (nAb) titres in SARS-CoV-2 naïve populations, meaning they may be less protected against future infection compared with those previously exposed to other variants or vaccinated5.”
  • These two population groups primed by different antigens will likely have different antibody responses as the sera of individuals primed by pre-Omicron variants or vaccines poorly neutralize the Omicron BA.1/2 variant and vice versa.

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.
