Anti-Receptor binding domain (RBD) IgG avidity in plasma from elderly nursing home residents. Total antibodies. A Anti-RBD IgG avidity indexes (%) before and after one (pre-3D and post-3D, respectively) or two (pre-4D and post-4D, respectively) COVID-19 vaccine booster doses. B Anti-RBD IgG avidity indexes (%) in vaccinated/SARS-CoV-2-experienced (Vac-ex) and vaccinated/SARS-CoV-2 naïve (Vac-n) at the different sampling times. The number of plasma samples available for analyses at the different sampling times is shown. Bars indicate medians and IQRs. P values for differences are shown.
