Active treatment and passive immunization with mAbs targeting key antigens represents a promising approach to preventing and mitigating infectious pathogen-caused illness, particularly in Low and Middle-Income Countries (LMICs). While the development of mAbs against infectious disease has lagged behind that of immune disorders and oncology targets, recent efforts against infectious diseases have seen increasing focus with the development of mAbs against RSV, Ebola strains, and SARS-CoV-2, among others.

The price for mAb treatment remains out of reach for most patients in middle income countries and nearly all patients in low-income countries. It is therefore clear that a new approach to manufacturing mAbs is needed. Here, high-productivity, high-yield mAb fed-batch production is demonstrated using clonal variants of ZAC-3, a mAb directed against the conserved core/lipid A region of V. cholerae lipopolysaccharide (LPS).
