Abstract

Influenza viruses cause respiratory illness that affects 8% of the U.S. population annually. However, current influenza vaccines have a limited efficacy of only 40-60%. This highlights the need for a universal vaccine design that can generate broadly neutralizing antibodies against influenza surface protein hemagglutinin (HA). Previous work by our group identified HA-specific monoclonal antibodies (mAbs) from serum samples through high-throughput antibody profiling. In this study, three of the identified mAbs were generated using mammalian cell expression and their binding affinity against three HA antigens was characterized via Enzyme-Linked Immuno-Sorbent Assay (ELISA). The ELISA results demonstrated specific binding affinity towards B/Yamagata/18/1998 HA but not towards B/Washington/02/2019 HA and B/Brisbane/60/2008 HA. These findings provide insights into human antibody response after vaccination and suggest further biophysical and competition studies to identify target epitopes on HA antigens.
