• Data evaluating the impact of cell-based quadrivalent influenza vaccines suggests an additional 31%–39% of influenza cases may have been prevented among persons 0–64 years of age during the 2017-2020 U.S. flu seasons.1
• Vaccination of children 6 months to 17 years of age with cell-based quadrivalent influenza vaccines would be cost-effective in >95% of simulations, compared to traditional egg-based vaccines based on modeling data from 2011/12 and 2017/18 U.S. flu seasons.2
• Influenza vaccination with an adjuvanted quadrivalent influenza vaccine or standard-dose egg-based quadrivalent vaccine significantly reduced cardiovascular, respiratory, and other complications of influenza among U.S. adults 65 years of age and older over the 2018/19 and 2019/20 influenza seasons.3

• Results from a retrospective cohort study from 2015 to 2020 demonstrated a notable rise with increasing age in pneumonia-related medical encounters following an influenza encounter.1
• Results from a retrospective cohort study during the 2019/20 season demonstrated the benefit of an adjuvanted influenza vaccine in prevention of influenza-related medical encounters among adults 65 years and older.2
• Results from a study across three consecutive influenza seasons showed that vaccination with cell-based influenza vaccines resulted in lower rates of test-confirmed influenza compared with traditional egg-based vaccines.3

• CSL Seqirus will deliver further H5N8 A/Astrakhan antigen to support the U.S. government's pandemic preparedness activities
• This is the third influenza pandemic preparedness award to CSL Seqirus in the last two years, building on a longstanding partnership with BARDA

• CSL Seqirus is the only influenza vaccine manufacturer that offers differentiated vaccine options for individuals six months of age and older.
• Since the COVID-19 pandemic, there has been a significant drop in influenza immunization rates and high levels of influenza-related illness, underscoring that flu is an ongoing threat.1,2
• The Centers for Disease Control and Prevention (CDC) recommends annual influenza vaccination for all eligible people aged six months and older, as a critical tool to help prevent flu and lessen the severity of influenza-related illness and potentially life-threatening associated complications.3

CSL to access late-stage next-generation mRNA platform technology, enabling development of vaccines for COVID-19, influenza, multi-pathogen pandemic preparedness and other respiratory pathogens

• CSL Seqirus will manufacture and clinically assess a cell-based, adjuvanted pre-pandemic influenza vaccine candidate to support the U.S. government’s pandemic preparedness activities
• Third influenza pandemic preparedness award to CSL Seqirus under a multi-year agreement with Biomedical Advanced Research and Development Authority (BARDA)

Data published in Molecular Therapy – Methods and Clinical Development confirm the potential preclinical benefit of the sa-mRNA technology platform, the next generation of mRNA vaccine technology

• This year marks the first full season that Seqirus’ portfolio of innovative influenza vaccines provides a differentiated vaccine option for people of all ages who are eligible in the U.S. to receive a flu shot
• Seqirus will offer FLUCELVAX® QUADRIVALENT (Influenza Vaccine), the first and only cell-based quadrivalent influenza vaccine, which is now available for eligible persons six months of age and older
• Seqirus will offer FLUAD® QUADRIVALENT (Influenza Vaccine, Adjuvanted), which is now preferentially recommended by the CDC’s Advisory Committee for Immunization Practices as one of the preferred vaccine options for adults 65 years and older, over standard-dose influenza vaccines

• Seqirus is officially recognized by the U.S. government as having successfully established domestic manufacturing capability for innovative cell-based seasonal and pandemic influenza vaccines.
• Holly Springs, N.C., facility is ready to deliver 150 million doses of pandemic influenza vaccine to the U.S. government in the event of an influenza pandemic.

• Renewal reaffirms longstanding, public-private partnership between Seqirus and the Biomedical Advanced Research and Development Authority (BARDA) to strengthen preparedness and rapid response capabilities for influenza pandemics
• Agreement includes provision for Seqirus to provide BARDA with supply of AUDENZ, the first-ever FDA-approved adjuvanted, cell-based pandemic influenza vaccine, which was developed in partnership with BARDA

New facility in Waltham, Massachusetts, will support CSL’s growing R&D portfolio, including the self-amplifying mRNA technology platform, the next generation of mRNA vaccine technology, for seasonal and pandemic influenza vaccines.
