Fig. 4: Influence of viral symptoms on the levels of antibodies reactive to common human coronaviruses (HCoVs) in human milk.

From: Previous viral symptoms and individual mothers influenced the leveled duration of human milk antibodies cross-reactive to S1 and S2 subunits from SARS-CoV-2, HCoV-229E, and HCoV-OC43

A HCoV-229E S1 + S2-reactive SIgA/IgA, B HCoV-OC43 S1 + S2-reactive SIgA/IgA, C HCoV-229E S1 + S2-reactive SIgM/IgM, D HCoV-OC43 S1 + S2-reactive SIgM/IgM, E HCoV-229E S1 + S2-reactive IgG, and F HCoV-OC43 S1 + S2-reactive IgG. Letters a–c show statistically significant differences between groups (p < 0.05) using two-way ANOVA followed by Tukey’s multiple-comparison test. Values are means ± SD, where n = 5 for mothers in the viral symptom group and n = 4 for mothers in the no-symptom group. Human milk samples were collected at four different time points across postpartum time for each mother.
