Influenza vaccine(Seqirus GmbH)

CSL Seqirus will supply millions of doses of adjuvanted cell-based vaccine to support Canadians, in the event the World Health Organization (WHO) declares an influenza pandemic. The continued detection of influenza viruses of pandemic potential, including highly pathogenic avian influenza infecting wild birds, poultry and mammals, underscores the pandemic threat posed by influenza and the potential public health risk . 1 MONTREAL , March 6, 2026 /CNW/ - CSL Seqirus has been awarded a new contract agreement to support the influenza pandemic preparedness plans of the Canadian government's Public Health Agency of Canada (PHAC). Under the terms of the agreement, CSL Seqirus has committed to rapidly manufacture and deliver millions of doses of cell-based adjuvanted influenza vaccines to help protect Canadians if an influenza pandemic is declared by the World Health Organization (WHO). Under a previous agreement with PHAC, CSL Seqirus was contracted to provide an egg-based influenza vaccine in the event of a pandemic. This shift towards cell-based vaccines builds on the successful introduction of cell-based Flucelvax ® , Influenza Vaccine (surface antigen, inactivated, prepared in cell cultures), into Canada's seasonal influenza program over the past six years. "This new contract with CSL Seqirus strengthens Canada's ability to respond quickly to a potential future flu pandemic. By securing access to millions of doses of flu vaccine if a pandemic is declared by the WHO, we are reinforcing our commitment to protecting health and being prepared and ready to act in the face of emerging public health threats," says the Honourable Marjorie Michel, Minister of Health. Cell-based manufacturing provides a proven technology platform for pandemic influenza vaccines. These benefits include scalability, reduced reliance on large volumes of critical materials, and the ability to rapidly produce vaccines using state-of-the-art technology. The introduction of this technology into Canada's pandemic preparedness plans will further bolster the country's already-robust provision which ensures whole-population flu pandemic vaccine coverage if needed. 2 "The health and safety of Canadians always comes first", says the Honourable Joel Lightbound, Minister of Government Transformation, Public Works and Procurement. "This new contract ensures Canada has guaranteed access to millions of vaccine doses and the capacity to respond quickly if a pandemic is declared. We're strengthening Canada's preparedness, reducing vulnerabilities in global supply chains, and making sure Canadians are protected when it matters most." As cases of avian influenza viruses of pandemic potential continue to be detected worldwide, there is critical importance in maintaining robust pandemic preparedness capabilities and strategic partnerships between governments and industry leaders in vaccine development. Gillian Stafford , Canadian Country Head Commercial Operations at CSL Seqirus, says: "A flu pandemic is an ever-present threat. If one strikes, our robust, rapid response capabilities will ensure all our Canadian counterparts have access to vaccines to help protect their populations. We're honoured to continue contracting with Canada, a leading country in pandemic preparedness, toward our shared goal of protecting public health." About Pandemic Influenza Influenza is a contagious airborne respiratory disease. 3,4 The risk of influenza-associated morbidity and mortality is greater with pandemic influenza than with seasonal influenza because there is likely to be little or no pre-existing immunity to the novel virus in the human population. 5 The timing and severity of pandemic influenza is unpredictable. Four influenza pandemics have occurred since 1918, with the 1918 pandemic being the most severe in recent history, with an estimated mortality of up to 50 million people worldwide. 6 About Avian Influenza Avian influenza spreads predominantly among birds. 7 Avian influenza viruses do not normally infect humans however humans have been infected with avian influenza viruses in rare cases. 8 Illness in humans from avian influenza has varied in levels of severity from no symptoms or mild illness to severe disease and death. 7 The spread of avian influenza from one human to another is very rare and typically has only spread to a few people. 7 For information on the persistent levels of highly pathogenic avian influenza seen in recent years, CSL Seqirus recommends referring to the WHO website, and CDC, ECDC or national guidance for opinion and guidance on risk. 9,10,11,12 About CSL Seqirus CSL Seqirus  is part of CSL (ASX: CSL).
