Abstract

Based on its genetic profile and preliminary in vitro and epidemiological data, the recently emerged SARS-CoV-2 Omicron variant is predicted to evade immune responses to some extent. We report a cluster of Omicron variant infections in individuals who had received full primary vaccination series and booster doses with mRNA vaccines. All patients experienced symptomatic COVID-19 but clinical manifestations were mild to moderate. Their SARS-CoV-2 viral RNA loads and anti-spike antibody levels were determined. This series proves that even three doses of mRNA vaccines may not be sufficient to prevent infection and symptomatic disease with the Omicron variant.

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.
