This is primarily a descriptive study that will quantify with 95% confidence intervals the mean IgG antibodies remaining in vaccinated healthy participants three to nine months after their COVID booster. At specified intervals during this period, a titer will be performed on blood drawn from participants to quantify the IgG antibodies to the SARS-CoV-2 spike protein.~This evaluation will not be performed in a lab with CLIA certification and this study will not be used to seek an EUA from the FDA. The FDA and CLIA regulate diagnostic laboratory testing but do not regulate surveillance testing.
