Fig. 1: IgG and IgA response in serum samples of vaccinated, infected, and negative individuals.
From: Immune response to SARS-CoV-2 variants of concern in vaccinated individuals

IgG (a, c) and IgA (b, d) response in sera from vaccinated (pre second vaccination (light blue, n = 25), post second vaccination (dark blue, n = 20)), infected (red) (n = 35), and negative (gray) (n = 20) individuals were measured with MULTICOV-AB. IgG (a) and IgA (b) response is shown as normalized RBD wild-type (wt) versus normalized nucleocapsid MFI values allowing for visualization of separation between the different groups. Increasing antibody titers in vaccinated individuals for IgG (c) and IgA (d) is shown with increasing days post vaccination, with samples colored based on whether they are before (light blue) or after (dark blue) the second dose. Lines indicate paired samples from the same donor. Source data are provided as a Source Data file.
