This study compares antibody responses in infants after influenza infection or vaccination, finding greater post-exposure responses following infection compared to vaccination.

This study evaluates antibody responses after a KP.2 spike mRNA vaccine dose, showing durable and broadly cross-reactive immunity against multiple SARS-CoV-2 variants, but reduced neutralizing activity against some emerging subvariants.

This study identifies an IgG3 subclass antibody that expands neutralization breadth against dengue and zika viruses by engaging a quaternary epitope through structural and functional analyses.

This study identifies FcγRI as the critical Fc receptor mediating antibody-enhanced ZIKV infection of placental macrophages through genetic and functional analyses.

This study investigates the immunogenicity and structure of a clade C HIV-1 Env trimer from a pediatric elite-neutralizer, showing it elicits strong autologous neutralizing antibodies and reveals key neutralizing epitopes.

This study stabilizes an HIV-1 clade C trimer using multiple platforms and shows improved antigenic and immunogenic properties.

The paper evaluates the effectiveness of an XBB.1.5 monovalent booster vaccine, showing improved antibody binding and neutralization against SARS-CoV-2 Omicron variants.
