    METHOD DETAILS: SARS-CoV-2 antibody ELISA: Antibodies to SARS-CoV-2 spike protein were detected using an established two step ELISA previously described (Ojeda et al., 2021).
    SARS-CoV-2 spike protein
    suggested: None
    Comparison of antibody concentration, neutralizing titer and neutralizing potency index were done using the Wilcoxon matched paired test in Figures 1C, 1D. 1E, 2A, 2B, 3A, 3B and S1.
    S1
    suggested: None
    Experimental Models: Cell Lines
    SentencesResources
    Cell lines: Vero E6, Vero-CCL81, Vero E6-TMPRSS2, or Vero-hACE2-TMPRSS2 cells (ATCC) and 293T ACE2/TMPRSS2 cells, kindly provided by Dr. Benhur Lee, were cultured at 37ºC in 5% CO2 in Dulbecco’s Modified Eagle’s high glucose medium (Thermo Fisher Scientific) supplemented with 10% fetal bovine serum (FBS)(GIBCO).
    Vero E6
    suggested: RRID:CVCL_XD71)
    Vero-hACE2-TMPRSS2
    suggested: None
    Recombinant VSV: Briefly, recombinant VSVs were rescued by infecting BSRT7/5 cells with vaccinia virus vTF7-3 and subsequently transfecting them with T7-driven support plasmids encoding VSV N, P, L, G, and VSV genomic cDNAs.
    BSRT7/5
    suggested: CCLV Cat# CCLV-RIE 0583, RRID:CVCL_RW96)
    Working stocks were generated on Vero-CCL81 or Vero E6-TMPRSS2 cells at 34°C.
    Vero E6-TMPRSS2
    suggested: None
    Viral stocks (VSV-eGFP-SARS-CoV-2), generated in Sean Whelan laboratory, were amplified in our laboratory using 293T ACE2/TMPRSS2 cells at an MOI of 0.01 in Dulbecco’s Modified Eagle’s medium containing 2% FBS at 37ºC.
    ACE2/TMPRSS2
    suggested: None
    Vero cells were used for these assays.
    Vero
    suggested: CLS Cat# 605372/p622_VERO, RRID:CVCL_0059)
    Software and Algorithms
    SentencesResources
    Viruses: SARS-CoV-2
    SARS-CoV-2
    suggested: (BioLegend Cat# 946101, RRID:AB_2892515)
    Absolute inhibitory concentrations (absIC) values were calculated for all patient sera samples by modeling a 4-parameter logistic (4PL) regression with GraphPad Prism 8.
    GraphPad Prism
    suggested: (GraphPad Prism, RRID:SCR_002798)

    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.
