Outcome Measures

Primary Outcomes (1)

  • Evaluation of the immunogenicity of the COVID-19 vaccines by measuring geometric mean titers (GMT) of SARS-CoV-2 antibody concentrations, and quantitative assays to evaluate RBD-binding IgG levels

    Evaluation of the immunogenicity of the COVID-19 vaccines prior to patients receiving a COVID-19 booster during the Fall 2023 through Spring 2024 and at approximately six months after the Fall2023/Spring 2024 COVID-19 booster. Quantitative assays will be used to evaluate RBD-binding IgG levels.

    6 and 12 months after third dose of the COVID-19 vaccine, with primary outcome being sustained antibody concentrations at 12 months

Secondary Outcomes (3)

  • Sustained cell-mediated immunity against Covid-spike proteins will be evaluated using IFN-ϒ ELISpot, which detects both CD4 and CD8 T cell effectors.

    during the Fall 2023 through Spring 2024 and at approximately six months after the Fall2023/Spring 2024 COVID-19 booster

  • Evaluate the persistence of memory B cell using memory B cell analysis.

    during the Fall 2023 through Spring 2024 and at approximately six months after the Fall2023/Spring 2024 COVID-19 booster

  • Sustained antibody concentration evaluating spike protein and receptor binding

    during the Fall 2023 through Spring 2024 and at approximately six months after the Fall2023/Spring 2024 COVID-19 booster
