    Whole blood staining and flow cytometry: Fresh whole blood (200μl per stain) was used to measure CD4+CXCR5+ICOS+PD1+ follicular T cells (Tfh) and CD3-CD19+CD27hiCD38hi antibody-secreting B cell (ASC; plasmablast) populations as described3 as well as activated HLA-DR+CD38+CD8+ and HLA-DR+CD38+CD4+ T cells, inflammatory CD14+CD16+ and conventional CD14+ monocytes, activated HLA-DR+CD3-CD56+ NK cells, as per the specific antibody panels (Supplementary Table 1; gating strategy is presented in Supplementary Fig.1).
    CD3-CD19+CD27hiCD38hi antibody-secreting B
    suggested: None
    antibody-secreting
    suggested: (Félix A. Rey; Pasteur Institute Cat# C10, RRID:AB_2725800)
    Detection of IgG and IgM antibodies in SARS-CoV-2 -infected vero cells: Immunofluorescence antibody tests for the detection of IgG and IgM were performed using SARS-CoV-2-infected vero cells that had been washed with PBS and methanol/acetone fixed onto glass slides.
    IgM
    suggested: None
    Prior to detection of IgM antibodies, samples were pre-treated with RF-SorboTech (Alere, Rűsselsheim, Germany) to remove IgG antibodies and rheumatoid factors, which may cause false-negative and false-positive IgM results, respectively.
    remove IgG
    suggested: None
    Software and Algorithms
    SentencesResources
    Flow cytometry data were analyzed using FlowJo v10 software.

    suggested: (FlowJo, RRID:SCR_008520)

    Results from OddPub: We did not detect open data. We also did not detect open code. Researchers are encouraged to share open data when possible (see Nature blog).


    Results from LimitationRecognizer: An explicit section about the limitations of the techniques employed in this study was not found. We encourage authors to address study limitations.

    Results from TrialIdentifier: No clinical trial numbers were referenced.


    Results from Barzooka: We did not find any issues relating to the usage of bar graphs.


    Results from JetFighter: Please consider improving the rainbow (“jet”) colormap(s) used on page 10. At least one figure is not accessible to readers with colorblindness and/or is not true to the data, i.e. not perceptually uniform.

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
