Fig 1. Heat map identifying amino acid motifs preferentially recognized by IgG from vaccinated subjects.

Fig 1

Amino acid motifs were identified among the peptides immunoprecipitated by IgG from vaccine recipients using IMUNE algorithm and the level of enrichment (fold increase) in serum of individual subjects relative to pre-pandemic control subjects is depicted in the heat map. Samples 1–20 are pre-vaccine and samples 21–40 are the same subjects after Pfizer-BioNTech COVID-19 mRNA vaccination. Subjects 41–48 are from subjects that received Moderna vaccine. Samples 49–53 are vaccinated subjects that previously had COVID-19.
