Distribution of SARS-CoV-2 spike protein RBD total antibody AI values using a home-brew ELISA in pre- and post-COVID-19 vaccination serum and saliva samples. Serum and saliva were obtained from 40 individuals prior to and after COVID-19 vaccination. Antibody indices were measured using a laboratory-developed SARS-CoV-2 total antibody ELISA. The positive antibody index cut-off for serum samples was 4.0 and 2.8 for saliva samples. (a) Changes in AI pre- and post-vaccination in serum and saliva in the context of the positive cut-off value for each sample type. (b) Pre- vs. post-vaccination AI ratios in serum and saliva.
