Results of cellular proliferation assays performed with gradient‐isolated peripheral blood mononuclear cells (PBMC) stimulated with the indicated antigen‐specific and polyclonal stimuli in classical plate assays for 7 days. Shown is the summary of stimulation indices (SI, y‐axis) of PBMC which were incubated with the indicated stimuli (x‐axis). The bars represent the median, whiskers the Hodges‐Lehmann 95% confidence intervals, dark blue circles show proliferation of PBMC of COVID‐19 convalescent patients, red circles those of non‐exposed healthy controls and light blue squares those of vaccinees. M‐mix, SARS‐CoV‐2 matrix protein peptide mix; N‐mix, SARS‐CoV‐2 nucleocapsid protein peptide mix; PHA, phytohemagglutinin; S‐mix, SARS‐CoV‐2 spike protein peptide mix; SEB, Staphylococcal enterotoxin B; TBE, tick borne encephalitis antigen; TT, tetanus toxoid. Data show the summary of 35 COVID‐19 convalescent patients, except 31 for SEB, 36 healthy controls, except 32 for SEB, and 40 vaccinees. p values were calculated by Tuckey's test. Only significant differences are shown. ***p < .001
