Key Points

The study aims to identify critical factors influencing the breadth of antibodies against SARS-CoV-2 following infection and vaccination.
Analyzed antigen-specific B cell profiles from subjects infected with SARS-CoV-2 and vaccinated individuals.
Used deep profiling techniques to assess antibody breadth.
Examined correlations between B cell characteristics and antibody responses.
Identified significant determinants of antibody breadth linked to specific B cell signatures.
Demonstrated that a broader antibody response correlates with diverse B cell activation post vaccination.
Found variations in antibody breadth related to individual immune profiles.

Uncovers key determinants of SARS-CoV-2 antibody breadth after infection and vaccination, suggesting implications for immune response.

Antigen-specific B cell profiling uncovers key determinants of SARS-CoV-2 antibody breadth after infection and vaccination.
