Extended Data Fig. 3. Mucosal and peripheral IgG spike-specific binding antibody responses by ELISA.
IgG spike-specific binding antibody responses were assessed before and after boosting by ELISA in (a) bronchoalveolar lavage (BAL), (b) nasal swabs (NS), and (c) serum. Responses were measured against SARS-CoV-2 WA1/2020 (blue), BA.1 (green), BA.5 (purple), and BQ.1.1 (black) spike proteins. Missing symbols indicate absence of data. Dotted lines represent limits of quantitation. Medians (red bars) are shown. n = 40 biologically independent animals.
