CSL Behring and the Plasma-Derived Therapy Landscape
CSL Behring is the core driver of CSL’s plasma-based therapies portfolio. This business unit specialises in treating rare and serious diseases including immune deficiencies, bleeding disorders, and neurological conditions. Plasma collection centres serve as a backbone for the division, enabling the sourcing of raw plasma through a global network.

The therapies are developed using advanced fractionation techniques, and the unit operates major production sites in the United States, Germany, and Switzerland. These facilities enable mass production and supply to meet therapeutic demand in regulated markets. CSL Behring’s contribution extends to treating patients across multiple continents and is supported by innovation in recombinant and monoclonal antibody technologies.

Vaccine Division and Global Public Health Initiatives
CSL Seqirus plays a key role in influenza vaccine development and distribution. The division ranks among the global suppliers of seasonal influenza vaccines and pandemic preparedness solutions. CSL Seqirus operates production sites in Melbourne, Liverpool, and North Carolina, supporting public immunisation programs in collaboration with global health authorities.

The division also manages proprietary adjuvant platforms, which enhance vaccine immune response and duration. These capabilities support both pre-pandemic and pandemic response efforts. Through the development of cell-based and egg-based vaccines, the company addresses the evolving strains of influenza in regions with diverse epidemiological trends.
