The growing challenge of antimicrobial resistance (AMR) requires innovative strategies to combat multidrug-resistant infections. Vaccination is an effective approach, often considered a potential solution, however, its application against some of the most challenging multidrug-resistant bacteria, has been unsuccessful so far. In contrast, passive immunotherapy using high-titer specific antibodies can offer immediate solutions for infections where conventional antibiotics fail. This study describes the adaptation of the Cohn 6th cold ethanol fractionation method for small plasma pools, enabling the production of high-quality intravenous immunoglobulin (IVIG) products in resource-limited settings. Using small-scale plasma batches (12 L), the modified protocol achieved a yield of 4.5 ± 0.2 g/L IgG with > 98 % purity, meeting European Pharmacopoeia requirements. Additional purification, viral safety, and filtration steps ensured sterility, low endotoxin levels, and robust viral inactivation. Safety evaluations confirmed sterility, absence of pyrogens, and stability over 24 months. This scalable methodology provides a practical platform for developing hyperimmunoglobulin products targeting AMR pathogens, particularly in resource-limited countries where large-scale fractionation infrastructure is unavailable and also not suitable. Our future efforts will focus on integrating this platform into combination therapies to enhance clinical outcomes in AMR infection management.
