Fig. 3: Mucosal and peripheral IgA spike-specific binding antibody responses.
From: Mucosal boosting enhances vaccine protection against SARS-CoV-2 in macaques
a–c, IgA spike-specific binding antibody responses were assessed before and after boosting using ELISA in BAL (a), nasal swabs (b) and serum (c). Responses were measured against SARS-CoV-2 WA1/2020 (blue), BA.1 (green), BA.5 (purple) and BQ.1.1 (black) spike proteins. The missing symbols indicate the absence of data. The dotted lines represent the limits of quantification. Median (red bars) values are shown. n = 40 biologically independent macaques.
