Any biotherapeutic needs to maintain a high standard of purity. Viral contaminants can potentially alter the biological activity of the product, leading to reduced efficacy or adverse effects, and pose risks to patients health.
Viral contamination can occur at various stages of the manufacturing process, from raw materials to final product packaging. Furthermore, detecting viral contamination is more complex than identifying other types of microbial contaminants, making effective viral clearance studies particularly challenging and intricate.
