FIGURE 1.

Serum concentration of antibodies to the SARS-CoV-2 spike protein receptor binding domain and INF-γ SFU measured in OLT recipients and LUT recipients 60 days after the 2nd dose of the BNT162b2 vaccine and 60 days after the 3rd dose. (A): anti-SARS-coV-2 antibodies in OLT recipients. (B): anti-SARS-coV-2 antibodies in LUT recipients. (C): INF-γ SFU in OLT recipients. (D): INF-γ SFU in LUT recipients. The lines within the boxes indicate the median, the edges of the boxes are the lower and the upper quartiles (the interquartile range), the lines extending from the box (whiskers) indicate the adjacent values (the most extreme values that are still within a distance of 1.5 times the interquartile range from the nearest quartile) and the black dots beyond the whiskers are outliers. The white dots indicate individual values and the lines join the measurement on the same subject after the 2nd and the 3rd dose. INF, Interferon; LUT, Lung transplant; OLT, Orthotopic liver transplant OLT; PBMC, Peripheral blood mononuclear cells; SFU, Spot forming units.
