Abstract
Methods are provided for the manufacture of plasma-derived immunoglobulin G compositions highly enriched for anti-parvo B19 immunoglobulin G. The methods provided do not affect the manufacturing processes or capabilities for producing plasma-derived IgG therapeutics. Plasma-derived IgG compositions that are highly enriched for anti-parvo B19 immunoglobulin G are also provided. Methods for treating parvo B19 infections by administration of plasma-derived IgG compositions highly enriched for anti-parvo B19 immunoglobulin G are also provided.
