Abstract

Virus neutralization remains the gold standard for determining antibody efficacy. Therefore, a high-throughput assay to measure SARS-CoV-2 neutralizing antibodies is urgently needed for COVID-19 serodiagnosis, convalescent plasma therapy, and vaccine development. Here, we report on a fluorescence-based SARS-CoV-2 neutralization assay that detects SARS-CoV-2 neutralizing antibodies in COVID-19 patient specimens and yields comparable results to plaque reduction neutralizing assay, the gold standard of serological testing. The fluorescence-based neutralization assay is specific to measure COVID-19 neutralizing antibodies without cross reacting with patient specimens with other viral, bacterial, or parasitic infections. Collectively, our approach offers a rapid platform that can be scaled to screen people for antibody protection from COVID-19, a key parameter necessary to safely reopen local communities.

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

  • Together with reports of preserved neutralization of SARS-CoV-2 with key B.1.1.7 and B.1.351 spike mutations and of pseudovirus with the full B.1.1.7 spike mutation set, our data indicate broad BNT162b2-elicited immune recognition.

    “Together with recent reports of the preserved neutralization of SARS-CoV-2 with key S mutations found in the B.1.1.7 and the B.1.351lineage 39,40 , and neutralization of pseudovirus bearing the full set of mutations of B.1.1.7 S 41 , our data indicate broad BNT162b2-elicited immune recognition 2,13,14 .”

    The Results describe neutralization testing with COVID-19 patient sera, and the Discussion describes the assay’s use in vaccine trials. Our copy does not report BNT162b2-elicited immune recognition; searches for BNT162b2 and the B.1.1.7 and B.1.351 mutations found no supporting passage. The variant-neutralization reports in the citing sentence are attached to other citations. (LLM, conf=0.76)

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.
