A preprint abstract from biorxiv.org discusses the potential use of complement therapeutic Factor H-IgG proteins as pre-exposure prophylaxes against Lyme borreliae infections. Lyme disease is a common vector-borne disease caused by Borrelia burgdorferi bacteria, and currently, there is no effective prevention available.
