Primary Outcome Measures

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

Secondary Outcome Measures

Name	Time	Method
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	Evaluation of the persistence of memory B cell in approximately one-third of participants.
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	Evaluation of sustained cell mediated immunity against Covid-spike proteins. IFN-ϒ ELISpot, which detects both CD4 and CD8 T cell effectors, will be used to detect T-cell immunity to the Covid-spike protein or peptides.
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	The NIH ELISA assay will be used to evaluate change in S and RBD (IgG and IgM) antibody titers.
