The BNT162b2 mRNA SARS-CoV-2 vaccine induces transient afucosylatedIgG1 in naive but not antigen-experienced vaccinees

J. Van Coillie, T. Pongracz, J. Rahmoeller, H.-J. Chen, C. E. Geyer, L. A. van Vught, J. S. Buhre, T. Sustic, T. L. J. van Osch, M. Steenhuis, W. Hoepel, W. Wang, A. Lixenfeld, J. Nouta, S. Keijzer, , Fatebenefratelli-Sacco Infectious Diseases Physic

The paper examines afucosylated IgG1 responses after BNT162b2 vaccination, finding transient responses in naive individuals that correlate with second-dose antibody levels.

Afucosylated immunoglobulin G responses are a hallmark of enveloped virus infections and show an exacerbated phenotype in COVID-19

M. D. Larsen, E. L. de Graaf, M. E. Sonneveld, H. R. Plomp, F. Linty, R. Visser, M. Brinkhaus, T. Sustic, S. W. deTaeye, A. E. H. Bentlage, J. Nouta, S. Natunen, C. A. M. Koeleman, S. Sainio, N. A. Kootstra, , G. Vidarsson

The paper shows that afucosylated IgG responses are common in enveloped virus infections and are more severe in COVID-19, with implications for immune response and pathology.
