Fig. 1From: Higher plasma levels of thymosin-α1 are associated with a lower waning of humoral response after COVID-19 vaccination: an eight months follow-up study in a nursing homeAge-related differences in the humoral response to the BNT162b2 vaccine. A Comparison of anti-S antibody titers between study groups at T1. Differences in anti-S IgG antibodies were maintained even when the two outliers from the young group (**) were excluded (p = 0.048). B Correlation between age and the log10 of anti-S antibody titers at T1. p values < 0.05 were considered statistically significantBack to article page
