CD79A and infection: In the current study, we have assessed both quantitative and qualitative aspects of RSV-specific serum antibodies (e.g. IgG/IgA binding titers, ADCD, ADCP, ADNKA) cross-sectionally in different age groups (11-, 24-, and 46-months, adults, and older adults; n = 31–35 per group) and longitudinally following natural RSV infection in (older) adults (2–36 months post-infection; n = 10).
